Have brushless motor and the brushless motor performance comparison
1, the scope of the
: brushless motor is often used in the control request is higher, higher speed of devices, such as model aircraft, precision instruments and meters, etc on the motor speed control strictly, spins at very high device.
carbon brush motor: usually brush motor power equipment are used, such as hair dryer, auto air conditioning fan brushless motor, the motor of the 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, the service life of the
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 it is easy to cause the bearing wear. Running current, motor magnets demagnetization, reduce the service life of the motor.
3, use effect
brushless motor, are usually digital frequency conversion control, controllability is strong, from a few revolutions per minute, yuntai brushless motor, 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, the series motor can reach 20000 RPM, but life is short.
4, energy-saving aspects contrast, 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 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, noises
noises have nothing to do with whether a brush motor, main is to look at the bearing and click on the matching of the internal components.
