The embodiment of the invention provides a star sealing device for an elevator and a motor winding parameter calculation method of the star sealing device, and relates to the technical field of elevator control. The device comprises a current and frequency detection unit which is used for acquiring signal parameters of a motor winding during star sealing; the micro-control unit is used for obtaining the car speed and the actual current value during star sealing based on the signal parameters and sending the car speed and the actual current value to an elevator main control board; the elevator main control board is in communication connection with the micro-control unit and used for receiving the car speed and the actual current value during star sealing so as to monitor the star sealing state of the motor winding, the micro-control unit and the elevator main control board can communicate, real-time transmission of motor winding current and elevator sliding speed information is achieved, an elevator is more controllable and safer, and the safety of the elevator is improved. The problem that when the star sealing function is executed in an existing method, an elevator main control system cannot obtain the current of a motor winding and motor sliding speed information, and consequently potential safety hazards are caused is solved.
