How does the brushless motor controller work?

  • August 31,2020.

Nowadays, the development of science and technology is faster and faster. In the era of advanced automation, many devices need electric motors. There are many types of motors, brush motors, brushless motors and so on. Brushless motors are widely used in model airplanes, medical devices, electrical appliances, electric vehicles and other fields.

Brushless motor has high reliability and many advantages. Brushless electricity without brush, friction greatly reduced, smooth operation, high speed. Brushless motor can work continuously for about 20,000 hours, with a service life of 7-10 years. The brushless motor's power consumption is still only 1/3 of that of the brushless motor. In addition, brushless motor also has no commutating spark, low mechanical noise and other advantages.

For brushless motors, commutation is left to the control circuit in the controller. It works as follows: brushless motor although there is no brush, but you need a motor governor to control the speed of the motor. Brushless motor adopts electronic commutation. The current in the coil is changed periodically by external electric modulation, thus forming a magnetic force in the right direction to drive the motor.

So, how does the brushless motor controller work? The brushless motor controller can achieve some functions that the brushless motor cannot achieve, such as adjusting the power switch Angle, braking the motor, reversing the motor, locking the motor, using the brake signal, stopping the power supply to the motor. The electronic alarm lock on the battery car now takes full advantage of these functions.
