What is the difference between a permanent magnet brushless motor and a brushless motor
Oct 28, 2024|
View:342Excitation method: The excitation method of permanent magnet brushless motor is to use permanent magnets to generate magnetic field, while the excitation method of brushless motor is to generate magnetic field through permanent magnets on the rotor. Therefore, a brushless motor can also be considered as a permanent magnet motor.
Control mode: The control mode of permanent magnet motor is mainly to control the speed and torque by changing the voltage and current of the motor, while the control mode of brushless motor is to control the speed and torque through the electronic governor. This control method can achieve more precise control, so that the brushless motor can maintain a stable speed and torque output at low speed and high load.
Because the brushless motor has better control performance and stable performance, it is more widely used in occasions that require high-precision control and high-speed operation, such as machine tools, printing machines, CNC machine tools and other high-precision equipment. Permanent magnet motors are more suitable for some low-precision, low-power occasions, such as electric bicycles, toys, etc.
