Abstract
To solve the starting problem of permanent magnet traction motors in rotating state,this paper proposes a starting tech-nology based on high-frequency injection(HFI)for initial speed recognition in rotating state.The technical principle and mathematical model of high-frequency injection of pulsating sine wave were studied,and the traditional high-frequency injection was improved to make it suitable for starting in rotating state,simulation calculation was carried out.Besides,a starting strategy for permanent magnet synchronous motor in rotating state was proposed based on high-frequency injection for initial speed recognition,and tests were designed to test and verify the pulsating sine wave high-frequency injection technology and the starting strategy in rotating state.Through re-search,it concluded that the pulsating sine wave high-frequency injection technology can track the actual position and speed of the rotor with high accuracy;the starting technology based on high-frequency injection in rotating state can accurately identify the speed of the motor when it starts up and effectively solve the motor starting problems under different working conditions.The test verifies the high-frequency injection technology for initial speed recognition and the starting strategy in rotating state.
