the motor controller about brushless motor controller the three advantages of brushless motor controller is compared to the first big advantage is that the efficiency of the brushless motor controller, have only in a rotating brush motor controller provides maximum torque at some point. Despite the motor controller can provide the same torque as the brushless motor controller, but have greater magnetic motor controller the need. Brushless motor controller can be rotated to in its biggest force (Torque)Under continuous rotation. This means that the smaller the size of the brushless motor controller can provide considerable power. Brushless motor controller, the second largest advantage is controllable feedback system can be used to control the brushless motor controller, to provide the required torque and rotational speed. If by battery power brushless motor controller, the precise control can reduce the energy consumption and heat loss, helps to extend battery life. Brushless motor controller is the third big advantage is high durability and low noise without brush brushless motor controller can provide high durability and low electrical noise. For a brush motor controller, the brush and commutator, due to the movement of the continuous contact wear and may produce a spark in the contact. In particular, the spark gap in the brush through commutator usually produce, strong spark can cause electrical noise. A special working condition if the transmission equipment, electrical noise factors in the motor controller design, the brushless motor controller is preferable.
