Three-phase variable-frequency permanent magnet synchronous motor for hoisting equipment with a power range of 132 kW to 5500 kW, a rated speed of 0-75 rpm, and an efficiency exceeding 95%. This motor is widely used in hoisting equipment for mines and coal mining applications. The rotor is excited by permanent magnet materials, enabling low-speed and high-torque power transmission. Controlled by a frequency converter, the motor can directly drive mine hoisting equipment. It offers advantages such as simple structure, compact design, gearless direct drive, four-quadrant operation, high efficiency and energy saving, large starting torque, strong overload capacity, soft start and stop, minimal mechanical impact, high control precision, reliability, compact size, easy installation, and a maintenance-free system.
