Brushless dc motor as crazy Wolf rushed into various industries, become worthy of the motor industry rising star. Brushless dc motor without brush and commutator, so its name. Is composed of main body of the motor and drive, is a kind of typical mechatronics product. What is the difference between it and the carbon brush? Below small make up detailed introduction for you. , the service 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: usually have brush motor continuous working life in more than a few hundred to thousand hours, to use the limit will need to replace carbon brush, otherwise easy to cause bearing wear. , scope of application: brushless motor, is often used in the control request is higher, higher speed of the device, such as model aircraft, precision instruments and meters for motor speed control strictly, spins at very high device. 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. , 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. , use effect: brushless motor, are usually digital frequency conversion control, controllability is strong, 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: the old general carbon brush motor starts working speed constant, speed is not very easy, can also be achieved series motor RPM, but life is short. And noise has nothing to do with whether a brush motor, main is to look at the bearing and motor with the internal components. And maintenance 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 motors, long service life, usually have a motor of The Times, but need to replace the motor is broken, but basic don't need daily maintenance. And the parameters of the model brushless motor, in addition to the overall dimensions,Diameter, length, diameter of axle, etc. ), weight, voltage range, no-load current, maximum current and other parameters, also an important index KV value, this value is unique to the brushless motor of a performance parameter, is brushless motor performance characteristics of an important data.
