The electric drive system for brushless DC motor

Because of the brushless DC motor has the same torque characteristic with DC motor.at the same time,but also overcomes the disadvantages of DC motor that carbon brush and slip ring. Combined with the advantages of F2812 in the control algorithm. This paper adopts brushless DC motor as the control object of electric drive system,and F2812 as the control core design scheme. We design a high precision and high efficiency electric drive system.
