双电机恒转矩节能无级调速技术

Technology of Energy-saving Constant Torque Stepless Speed Control by Bi-motor

针对恒转矩无级调速系统存在启动转矩低、能耗大及谐波影响等问题,本文提出一种采用双电机恒转矩节能无级变速调速技术,并论述了实现降低启动电流,提高启动转矩及恒转矩调速的方法。

The paper introduces the technology of energy-saving constant torque stepless speed control by bimotor, which is designed to deal with the problems of low starting torque constant torque, high energy-consuming, and harmonic influence in the stepless speed control system. The methods for reducing starting current, enhancing starting torque and speed control with constant torque are explained.
