Abstract

The invention discloses an elevator driving system. The elevator driving system comprises a fixedly arranged main body part and a rotating part which is rotationally installed on the main body part, and a magnetic-induction encoder is further arranged in the elevator driving system; the magnetic-induction encoder comprises induced parts arranged on the rotating part and a magnetic-induction sensing device which is matched with the induced parts and fixed to the main body part; and the induced parts are multiple convex teeth which are arranged around a rotating axis, and all the convex teeth and the rotating part where the convex teeth are located are of an integral structure. According to the elevator driving system, the induced parts in the magnetic-induction encoder and original parts in the elevator driving system are integrated into an integral structure, the structure of the elevator driving system is simplified, and meanwhile operating performance stability of the elevator driving system is guaranteed.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator drive system. Background technique [0002] The elevator drive system is the power equipment of the elevator, which is used to convey and transmit power to make the elevator run. In order to ensure the normal operation of the elevator, it is necessary to monitor the operating status of the elevator drive system. [0003] In the prior art, photoelectric encoders are usually used to detect the output speed and rotational position of the elevator drive system. Photoelectric encoders have high requirements for installation accuracy, and there are shortcomings such as signal loss and repeated counting during use. As far as the equipment is concerned, it cannot fully meet the security requirements. [0004] With the development of position and speed detection sensor technology, magnetic induction encoders have appeared. Magnetic induction encoders have the advantages of...
