Summary: | The invention provides an efficiency estimation method and device for a traction motor on a locomotive, equipment and a medium. The method comprises the following steps: acquiring torques, rotating speeds and rated voltages of a traction motor at different locomotive speeds; determining the stator current of the traction motor at different locomotive speeds based on the vector control model of the traction motor; determining power factors of the traction motor at different locomotive speeds based on the equivalent circuit model of the traction motor; determining the output power of the traction motor at different locomotive speeds according to the rotating speed and the torque of the traction motor at different locomotive speeds; determining the input power of the traction motor at different locomotive speeds according to the rated voltage, the stator current and the power factor of the traction motor at different locomotive speeds; and determining the efficiency of the traction motor at different locomotive |
