The invention discloses a motor operation parameter determination method and device, and relates to the technical field of motors. In the operation process of the motor, the current temperature rise of the motor rotor is determined according to the heating amount of the motor and the heat dissipation amount of the cooling machine oil to the motor rotor, the current temperature of the motor rotor is determined according to the last determined temperature of the motor rotor and the current temperature rise of the motor rotor, and the temperature of the motor rotor can be accurately estimated. And the influence of the motor rotor temperature on the motor torque can be accurately mastered, so that the motor torque control precision is improved.
