The invention discloses an elevator speed limiter and a control method of the elevator speed limiter. The elevator speed limiter is characterized in that a rotating shaft is supported on two side plates of a rack through bearings; a limiter wheel dish is fixedly arranged on the rotating shaft, a steel wire rope is wound around an upper half wheel groove in the limiter wheel dish, and an elevator lift car moves to drive the limiter wheel dish to rotate together with the rotating shaft through the steel wire rope by the utilization of friction force; the rotating shaft is sleeved with a ratchet wheel through a bearing, the ratchet wheel can rotate around the rotating shaft, and a photoelectric encoder is used for detecting the rotation speed of the limiter wheel dish; a pawl is arranged in cooperation with the ratchet wheel, and a stepping motor is fixedly arranged on a spoke of the limiter wheel dish and controls the pawl to rotate; a brake mechanism driven by a connecting rod is arranged, and the brake mechanism and the limiter wheel dish together clamp the steel wire rope to implement braking. The elevator speed limiter is simple in speed limiting structure and reliable in operation.
