介绍了VVVF调速系统在交流电牵引采煤机中的应用．通过实施低速转矩补偿、鼠笼式异步电动机的特殊设计、动态制动和抗干扰等措施后，VVVF调速系统具有良好的转矩转速特性，完全适合采煤机的牵引要求． The application of VVVF governor system in AC traction shearer is introduced. Through the implementation of low-speed torque compensation, squirrel-cage asynchronous motor special design, dynamic braking and anti-interference measures, VVVF speed control system has a good torque speed characteristics, fully suitable for shearer traction requirements.
