Low-speed energy feedback braking method for motor system of rod pumping equipment

This paper focuses on the principle of electromagnetic braking and energy feedback when the motor speed is lower than a certain speed of no-load motor, and puts forward a simple control method of low-speed energy feedback braking. Through computer simulation and prototype experiment, it can be seen that the control method proposed in this paper can easily achieve the low-speed energy feedback braking effect of the electric vehicle water magnetic brushless direct charging motor system, and ensure the safety of vehicle driving.
