The invention provides a motor stalling test method and device and a vehicle electric drive system, and belongs to the field of automobiles, and the method comprises the steps: collecting the current of a permanent magnet synchronous motor and the rotating speed of the motor; acquiring a first reference current of the permanent magnet synchronous motor; the amplitude of the first reference current is kept unchanged, components of the first reference current on the direct axis and the quadrature axis are reconstructed based on the motor rotating speed, and second reference current is obtained, so that when the current of the permanent magnet synchronous motor is equal to the second reference current, the motor rotating speed of the permanent magnet synchronous motor tends to 0; adjusting the AC voltage of the permanent magnet synchronous motor based on the current of the permanent magnet synchronous motor and the second reference current; and when it is detected that the motor rotating speed of the permanent magnet synchronous motor is not greater than the preset rotating speed, performing a locked-rotor test on the permanent magnet synchronous motor. External force does not need to be applied to the permanent magnet synchronous motor, the permanent magnet synchronous motor is controlled to be locked by the internal logic of the permanent magnet synchronous motor, the locked-rotor test cost is reduced, and the convenience is improved.
