Research on variable frequency speed control system of External rotor permanent magnet elevator |

| Abstract: | The traditional mine hoist adopts the transmission structure composed of AC asynchronous motor and reducer and the TKD electronic control system to adjust the speed.This paper puts forward the permanent magnet rotor winding machine, its external rotor permanent magnet synchronous motor with integrated structure of the hoist drum with advanced frequency control system, has the transmission of simple structure, high efficiency and energy saving, start frequency is low, low speed running smoothly, and maintain the advantages of small volume, low noise, solves the problems existing in the traditional elevator long-term.In this paper, the principle analysis and simulation research are carried out on the variable frequency speed control system of the permanent magnet external rotor hoist (which is divided into vector control system and direct torque control system). The research results show that the variable frequency speed control system can realize the speed (or torque) closed-loop control of the permanent magnet external rotor hoist, achieving the effect of smooth operation.The torque and speed responses of vector control system are smooth.The torque and speed of DTC are faster, but the torque ripple is larger, so the optimization method is needed to eliminate the torque ripple. |
