A vector control method of induction motor based on stator winding temperature sensing and fuzzy strategy is proposed to improve the short-term overload capacity of induction motor in safety.Compared with traditional vector control method based on winding temperature sensing,the proposed method controls the winding temperature by using fuzzy PI strategy and corrects the torque current component of the motor in real time through the temperature control results.A motor platform is designed to validate effectiveness of the proposed method.The experimental results show that the proposed method can further improve the short-term overload capacity and thermal safety of the induction motor,which can effectively promote the development of the drive control technology of the induction motor.
