Brushless motor with carbon brush motor respectively:
1. Scope of
: brushless motor is often used in the control request is higher, higher speed of devices, such as model aircraft, precision instruments and meters, etc to the motor speed control strictly, spins at very high equipment business.
carbon brush motor: usually brush motor power equipment are used, such as hair dryer, electric motor factory, household smoke lampblack machine, etc. Series motor speed also can achieve very high, but due to the wear of carbon brush, brushless motor is better than life.
2. Life
brushless motor: usually life in tens of thousands of hours in the order of magnitude, but due to the different bearing brushless motor service life are quite different.
carbon brush motor, there are usually brush motor continuous working life in more than a few hundred to 1000 hours, to use the limit will need to replace carbon brush, otherwise easy to cause bearing wear.
3. Use effect
brushless motor, are usually digital frequency conversion control, controllability is strong, the dongguan brushless dc motor, from a few rotations per minute (RPM), to the tens of thousands of revolutions per minute can be very easy to implement.
carbon brush motor, brushless motor general after starting work speed constant, speed is not very easy, can reach 20000 r/s series motor, but life is short.
4. Energy-saving aspects: relatively, brushless motor than series motor is controlled by frequency conversion technology energy saving a lot of, the most typical is the frequency conversion air conditioning and refrigerator.
5. Maintenance aspects in the future, need to replace carbon brush carbon brush motor, if the change is less than when causes the damage of the motor, brushless motor, long service life and is usually has more than 10 times of brush motor, but need to replace the motor is broken, but basic don't need daily maintenance.
6. Noise aspect has nothing to do with whether a brush motor, main is to look at the bearing and click on the matching of the internal components.
7. A motor is refers to the motor is dc input, controls the size of the controller only give it its current can speed; And brushless motor is actually a three-phase ac motor, brushless, yuntai motor controller to convert the dc to three-phase alternating current (ac), and according to the hall element sensor in the motor commutation make motor run properly. Direct, brushless motor brush than to have long life, strong start save electricity, but higher than brush controller cost controller.
at present, the model aircraft brushless motor, brushless controller, now has a brush has been basically eliminated. Electric vehicle controller is used to control the electric motor is starting, running, and, the speed, stop, and other electronic devices at the core of the control device of electric cars, it's like the electric car of the brain, are important components of the electric vehicle.
