Abstract: Mine motor has been widely used in transportation of underground ore-rock, equipment and personnel. In order to realize the integration of the hybrid charging and driving, a new circuit of hybrid charging and drive system is proposed by the reconstructing winding in permanent magnet synchronous motor. The battery is replaced by the battery-ultracapacitor as the energy storage device of the motor vehicle, the bi-directional DC/DC converter is used as voltage conversion device and the traditional DC motor is replaced by the isomeric permanent magnet synchronous motor to realize the integration of the hybrid charging and drive system and improve the driving performance and capacity of the mining motor vehicle. The integrated circuit of the hybrid charging and drive system with the new mine electric locomotive is simulated in MATLAB. The simulation results show that the integrated circuit of hybrid charging and drive system with the new mine electric locomotive can effectively improve the driving performance and capacity of the mine motor vehicle.
