The invention relates to the technical field of bullet train power supply, and provides a bullet train motor system capable of efficiently operating at different speeds, comprising a transformer, a first rectifier, a second rectifier and a traction motor which are electrically connected in sequence, the traction motor comprises a motor controller and a motor main body, and the motor main body comprises a stator and a rotor. The rotor comprises a first winding and a second winding which are wound on the stator, the input end of the motor controller is connected with the output end of the second rectifier, the output end of the motor controller is connected with the first winding and the second winding, and the motor controller controls the first winding and the second winding to be connected in parallel when the speed of the motor train unit is higher than the preset speed. The motor controller controls the first winding and the second winding to be connected in series when the speed of the motor train unit is lower than or equal to a preset speed. The motor controller can automatically adjust the connection mode of the windings according to the actual running speed of the motor train unit, it is ensured that the motor body can keep the optimal working state at different speeds, and the running stability and reliability of the motor train unit can be improved.
