Study on the influence of three-phase voltage unbalance on electromagnetic performance and vibration of high-voltage line-start permanent magnet synchronous motor
Since the operation of the high-voltage line-start permanent magnet synchronous motor (HVLSPMSM) does not need the control circuit and is directly powered by the grid, its operating stability is easily affected by the three-phase voltage unbalance. Thus, a 10 kV, 630 kW motor is taken as an example…
