There are many kinds of motor, we say the difference and the role of brushless motor and brush motor. Of course, there is a brush motor is less than Holzer. Brushless motor is to rely on Holzer to detect the position of the rotor, and then the controller to deal with the information from the Holzer to control the direction of rotation of the motor, the controller can also produce a wide signal to control the motor speed. From the control principle of the brushless DC motor is closed loop control, as far as the brush motor is the brush and the rotor to maintain the direction of rotation, the brush motor is open loop. Therefore, the utility model is more suitable for the application of electric bicycles and other products, the loss of the brushless motor is lower than that of the brush, and the range of the speed can be adjusted. There are many advantages of brushless than brush so the cost is relatively high, and the controller is more complex. Brushless DC motor is composed of motors and drives, alternating direct current current in different directions by the controller to achieve the motor coil current direction, no brush and commutator between rotor and stator brushless motor. When the brush motor is in operation, the coil and the commutator rotate, the magnetic steel and the carbon brush do not rotate, and the coil current direction is alternated with the commutator and the electric brush which is rotated with the motor. Holzer and electric vehicle brushless motor applications, first of all, the structure of the Holzer is very solid, small size, long life, relatively easy to install. The most important is the power consumption of high frequency and vibration resistance, not afraid of oil, etc. This is the best choice for motor vehicles. Holzer and motor controller in the use of stability, the start torque, no abnormal sound.
