A switched reluctance motor (SRM) drive system with a single power of 630 kW is developed. The dual-machine synchronous drive technology is successfully applied to the 8 000 t electric screw press in China. The electromagnetic parameters of the motor are designed and optimized, and the mechanical strength of the motor structure and connecting parts is calculated. The controller adopts the CAN isolation module to realize the real-time synchronization of the torque of multiple motors. Using composite copper bars and other technological measures to reduce the stray inductance and loop area of the main circuit, and suppress the IGBT peak voltage. The optical fiber drive mode is adopted to avoid strong magnetic field interference and ensure the signal transmission quality and system reliability. The test results show that all performance indicators of the SRM drive system meet the requirements of the 8 000 t electric screw press.
