摘要：
To discuss the problem that the on-line running time of the vacuum equipment production line is affected by the failure of vacuum dry pump unit and the need of production process, it is very significant to study the strategy of restarting at unknown speed of the canned induction motor for vacuum dry pump. In order to find the optimal moment of restarting and ensure the success of restarting at unknown speed, it is necessary to study the speed of motor and the stator residual voltage characteristics after the power off. Therefore, according to the space vector model of canned induction motor, a speed sensorless speed estimation model based on flux observation of voltage-current hybrid rotor was established, and the speed estimation method during the power off and the analytical formula of stator residual voltage after power off were deduced. By focusing on the amplitude and phase-angle characteristics between the stator residual voltage and the virtual reinput voltage, the first and the secondary restart points of the control system were determined. Taking the canned induction motor unit for 4 kW vacuum dry pump as an example, through model simulation and power-off residual voltage experiment, the good applicability and accuracy of the control method in pump engineering were verified, the speed stability time is less than 0. 5 s, and the impact current decreases by 59. 18% on average. © 2024 Editorial Department of Electric Machines and Control.
