The present invention discloses a method and device used for providing motor stator current values, wherein the method comprises the steps of based on an equation formed on the condition that the stator current values, the motor electromagnetic torques and the motor parameters satisfy the motor performance requirements, calculating the stator current values respectively corresponding to the rotating speed points in a motor constant torque area and a motor constant power area under different torques, providing the calculated stator current values to a motor control module, so that the motor control module utilizes the queried stator current values to control a motor. The motor control module can obtain the accurate stator current values respectively corresponding to the rotating speed points in a motor full-rotating speed section under the different torques, so that the motor can be controlled more accurately.
