DC Electrical Motors for Cars

Electric cars are rechargeable vehicles powered by electric motors. Electric motors for cars convert electrical energy into mechanical energy. Controllers regulate and control power received from rechargeable batteries to run the motors. The motors could be AC or DC motors. DC motors for electric cars could be further classified as permanent magnet, brushless, and shunt, series and separately excited. The DC uses electricity and a magnetic field to produce torque, which rotates the motor. The simplest DC electrical motor comprises of two magnets of opposite polarity and an electric coil forming an electromagnet. The properties of attraction and repulsion are used by the DC electrical motor to convert electricity into motion — opposing electromagnetic forces of magnets generate torque causing the DC motor to turn. Characteristics desirable of electric motors for cars include peak power, ruggedness, high torque-to-inertia, high peak torque, high speed, low noise, minimal maintenance and ease of use. Current generation electric motors are combined with inverters and controllers for a wide range of torque.

 

The abundance of series DC motor has allowed it to be tested on a variety of vehicles. The Series DC are robust and long-lasting, and the power density provides the best value for money. The torque curve suits a variety of traction applications. However, it is not as efficient as the AC Induction motor. The commutator brushes wear out and maintenance activities are required periodically. It is also not suitable for regenerative braking, that allow vehicles capture kinetic energy to recharge batteries.

 

DC motors are simpler and cost less, and have been widely used in demonstration electric vehicles. Brushless DC has no commutators, and is more powerful and efficient than commutator motors. Such DC motors, however, require more sophisticated controllers. Brushless DC in electric cars can give efficiencies up to 90%, and no servicing is required for up to hundred thousand kilometers. Experts at Floyd Associates (2012) argue that electric cars with DC Brushless motors can achieve the highest speed but slowest acceleration; AC Induction can achieve the fastest acceleration with average top speed; Permanent Magnet motors can achieve top speed and average acceleration; and Switched Reluctance motors provide the most cost-effective solution.

A DC Gear Motor Enhances Your Actuator’s Performance

When you purchase a linear actuator, you take no chances with its quality. The same should ideally apply to the DC gear motor that is used in conjunction with linear actuators. As is the case with actuators, there is also ample choice when it comes to DC gearmotors. Before you choose the final product, it is important to discuss your requirements with your chosen manufacturer. Ultimately, this will ensure that there are no hindrances in your desired applications.

 

The defining characters of a motor gearbox are its versatility and customization. There are several combinations in this such as DC voltage, sensor options and gear ratio.

 

Then again, there are gearbox options that are typically used to power most fifth wheel landing gear systems. You could choose to procure them with or without a switch and wire harness. For RV slide-out applications, there are specially designed gearboxes and they are a heavy-duty right angle drive gearbox. They are also referred to as center-drive systems. For medium duty applications, manufacturers offer worm drive and spur gear driven gearbox. To eliminate back-drive potential of actuators, you could employ gearboxes with electric brakes.

 

Alternatively, you could also opt for a DC gear motor that can be produced with a variety of output shaft combinations and manual crank capabilities. If you need exceedingly high levels of strength and reliability, you could also make use of an advanced gearbox that features a heavy-duty combination worm drive and spur gear drive. In addition to all these varieties, there are several manufacturers that will also offer you customized designs to meet your exacting specifications. Customization is chosen by several OEMs and contract manufacturers. By sending drawings and other specifications to the manufacturer, you can easily get a prototype and then finalize the actual product.

 

When you decide to use a DC gearmotor in conjunction with your linear actuator, it is important to see if the housing, components and lubrication is up to the mark. This helps maximize the performance potential of the gearbox. The housing is often made with materials such as cast aluminum and bronze. The other important point to check is the energy efficiency and maintenance issues. A gearbox that is energy-efficient but requires repetitive maintenance is certainly not a good choice.

 

Finally, a lot depends on the experience and manufacturing capabilities of the firm you are placing an order with. It is prudent to check their background and track record over the internet before you make a final purchase decision for your DC Gear Motor.

Hsiang Neng’s DC gear motor is widely used by several of applications, such as magnetic bike, vending machine, game player, instrument and appliance, massage tools, stage spinning light, auto shutter, auto mah-jongg table, medical equipment. The DC gear motor is designed and manufactured in high precision and superior quality. All DC gearmotors are inspected by precise instrument and tools before dispatch. The production processes are conducted in accordance to ISO 9001:2008 standard to minimize defective rate and ensure the highest performance the DC gear motors used in your applications.

DC Micro Motors for Surgical Optical Magnification

Medical application solutions have been incorporating miniaturization in order to provide more tools for surgical and medical use that can perform high precision operations with an extremely small margin of error. Miniaturized tools and DC micro motors have been developed for another surgical aspect – that of a surgeon’s vision.

 

It is a common sight to see a surgeon wearing a pair of magnifying glasses when performing a procedure. However, these spectacles are really inadequate in an era where medical procedures are becoming increasingly precise and quickly shrinking in scale. Fixed magnifying glasses limit the field of vision and a very small range where the lens are in focus.

 

This problem has set the framework for a medical application solution that incorporates auto-focus features with a full range of motion.

 

Head Mounted Vision System

 

A solution for enhanced vision for a surgeon has a hefty lift of specifications. The vision system must be hands free and light weight in order to be comfortably worn over long periods of time. In order to perform better than fixed lens, a wide range of magnification factors and an automatic focus are needed in order to compensate as a surgeon moves his head and operates in a different location. For extended functionality, the vision system needs to incorporate integrated lighting to handle shadows and an optional output to video camera provides a precise record everything a surgeon sees.

 

Clearly, these specifications are rather vigorous when coupled with the need to have all of this equipment fit comfortably in a doctor’s field of vision.

 

How DC Micro Motors Provide the Technical Solution

 

The system specified above will have a number of moving parts that have to respond quickly and accurately to a surgeon’s vision. Precision movements are achieved with a system of DC micro motors and DC gear-motors. Each lens requires two DC micro motors in order to properly set the order of magnification and focus distance. In order to achieve a high level of precision for a 10 micrometer resolution, the DC micro motors are equipped with a high quality set of magnets and coils supplemented with specialty lubricants to lower initial torque requirements.

 

The lubrication and fine surfaces are responsible for minimizing friction for higher resolution operation without jolts or backlash. Within the casing, the coils and magnets can reach temperatures over 100 degrees Celsius in order to operate continuously for several days without any limitation on service life or effectiveness thanks to the minimal amount of friction.

 

DC micro motors and other miniaturized components continue to lead the way in paving new innovations for medical application solutions. The ultimate goal of any miniaturized system is to obtain a maximum precision in the minimum space. This head mounted vision system is ideal for demanding positioning tasks, ranging from optical filters and focusing units to distribution of medical samples, inner-tube valves, and other micro positioning systems. Surgical tools continue to evolve in step with the medical field to the benefit of patients everywhere.

 

Hsiang Neng DC Micro Motor Manufacturing Corporation was established in 1985, which is a professional manufacturer of precise DC motors and geared motors. So far, we are mainly in the line of geared motors, planetary geared motors, mini motors, large-sized motors as well as motors for treadmills, actuators and so on products.

Why Install A Wall Fan?

The fan is more than just an appliance that you use to circulate air. In fact, this cooling device can improve ventilation and it can also help keep the room warm during winter months and cooler during the summer months. Ceiling fans and wall fans help you maximize the effect if your thermostat. What is a ceiling fan? This is the type of cooling device that is installed on the ceiling. What about the wall fan?

Advantages of a Stand Fan

Stand fans have risen immensely in popularity over the last few years because of the ease and convenience that they provide. Unlike ceiling fans, stand fans aren’t supposed to be rooted to one spot, and you can easily move them around according to your wishes. Most of the people who haven’t used these types of fans don’t quite know the advantages that are offered by these fans; otherwise they would most certainly prioritize the purchase of a stand fan over other things.

These fans are extremely easy to handle, and provide users with a very simple moving mechanism. Most of the fans that have the capability to stand on the ground can easily be moved to and fro, which means that you can keep them wherever you like and turn it by simply plugging the switch in the socket. The simplicity of these appliances prove to be a humongous advantage, because unlike ceiling fans (that are just hung on the ceiling and immovable), these standing models can easily be carried around.

For instance, if you are sitting out in your terrace and would like to have a smooth breeze, you can easily carry your stand fan out in your terrace, plug it in and let it cool you down. Furthermore, these fans are set on a rotational axis, which means they can provide cool air to more than one person. The rotor of the appliance is fixed on a sort of a parabola, so whenever you press the switch located on the back of the fan, it would automatically start moving at a certain degree, usually 180.

Stand fans generally don’t complete 360 degrees, because then the parabola has a chance of breaking and the dangers brought about by ball bearings that are located within the fan have restricted manufacturers from experimenting. The stand fan is also known as a pedestal, generally because of the fact that the long rod of the fan, which is also known as the ‘neck’, is connected to a pedestal at the bottom.

The pedestal allows appliance to stand on its own on the ground, and easily allows people to let it stand without any support of any kind. The rotational movement of the equipment makes it extremely easy to cool the atmosphere, and if you turn on the rotation and keep your pedestal fan in a room, you can be sure that a gentle coolness would quickly begin to settle in the atmosphere.

The most important thing to notice here is the fact that these fans are much cheaper as compared to others, especially ceiling fans, and the ease and comfort that they provide is also unparalleled. Furthermore, if used wisely, these fans can go on to have a very long life and provide you with relentless service for a period of several years. A stand fan can be easily purchased online or you can also purchase it from various different shops in the markets.

Fans are good Equipment for cooling a resting place such as a living room, bedroom, lounge room, garage and so on. Many people prefer buying a stand fan style. It is portable, user-friendly and very reliable.

The Advantages & Applications of Brushless DC Electric Motors

If you are building an item that requires DC Electric Motors (such as an electric wheelchair, a golf trolley or even refrigeration units), one of the most reliable and longest lasting types of motors are Brushless DC Electric Motors. But why are Brushless DC Electric Motors (or BLDC’s) so desirable?

First of all, it has very few moving parts, the only thing that moves is the commutator (which is a magnet), as a result there’s very little that can go wrong. Furthermore there’s very little friction, which also increases it’s lifespan, reliably and performance, but crucially also reduces it’s noise, heat production and sparks (so they’re perfectly safe to use around petrol engines, for example).

The engine works by having three (or more, but usually three) electromagnets around the outside of the commutator, held together by a ring. The electromagnets, when switched on, then pull the opposite pole towards it, whilst repelling the similar pole. This then turns the commutator, creating a spinning motion, which is connected to a gearbox or a driveshaft, resulting in power being driven to whatever the motor is used for.

They’re used for a lot, Brushless DC Motors are used for a variety of applications, as well as the ones mentioned at the top, they’re most common usage nowadays is within the IT industry. If you’re reading this on a desktop computer, there’s probably at least 3 near you! (one in the hard drive, one in the CD/DVD drive, and one in the PC cooling fan). That’s the low end usage, whereas the high end users are items such as hybrid cars. All in all, Brushless DC Motors are here to stay!

If you are in Europe, you can buy Brushless DC Motors from Fracmo, or find out more about DC Motors (Brushless, Brushed and more) from the DC Motor Guide.
