Brushless motor is a kind of electromechanical integration products, carbon brush motor is an important part of the brush motor. It can be seen that brushless motor and carbon brush motor is quite different, what specific different respectively? , scope of application: brushless motor is generally used in the control requirements are relatively high, has a high speed of devices, such as model aircraft, precision instruments and meters for motor speed control strictly, spins at very high equipment business; And carbon brush motor brush is an important part of, so the carbon brush motor power equipment commonly used are brush motor, such as hair dryer, and household washing machine is fine. , service life, the service life of the brushless motor is generally greater than the carbon brush motor. The service life of the brushless motor, usually in the tens of thousands of hours in the order of magnitude, but because of the difference of 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. , use effect: brushless motor generally is usually a digital frequency conversion control, strong controllability; The old general carbon brush motor starts working speed constant, speed is not easy. , energy-saving aspects: relatively, brushless motor adopts frequency conversion control technology is much larger than the series motor energy saving, so the brushless motor more energy-saving than carbon brush motor. And maintenance in the future: the need to replace carbon brush carbon brush motor, brushless motor don't need daily maintenance, but bad in motor directly. And noise: has nothing to do with a brush or brushless, basically see the internal structure of mutual cooperation. At present, now is brushless controller, 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 is like electric brain, are important components of the electric vehicle.
