The Intelligent Permanent Magnet Variable Frequency Speed Regulation Intergrated Motor system consists of two core parts: Permanent Magnet motor and inverter drive system. The Variable Frequency speed control system adopts self-developed sensor-less Vector Control technology to cope with the working conditions such as heavy load startup, low-speed large torque output, etc. It can perform heavy load startup at 0Hz, thereby realizing the high-efficiency drive for the Permanent Magnet motor. It saves the power cable between the inverter and the motor, solves the harmonic interference problem of the traditional configuration, and ensures the stable operation of the whole fully mechanized mining face equipment.
