【Abstract】 An integrating device of variable frequency and speed-down is an important driving and control unit which combines a variable frequency module, a variable frequency motor and a retarder. Its technical core is the variable frequency control module developed in this paper. The paper realized a variable frequency and adjusting speed system controled by vector based DSP and IPM. The operating priciple, hardware and software of the system are analyzed and studied. The testing results proved that it had good dynamic and static performance.更多还原
