Abstract

The invention relates to the technical field of mechanical transmission, and particularly relates to a magnetic resistance type soft starter. The starter comprises a salient pole rotor, a permanent magnet rotor arranged inside or outside the salient pole rotor along an axial direction, a plurality of groove bodies and a plurality of first conductive pieces, wherein an air gap is reserved between the permanent magnet rotor and the salient pole rotor; the plurality of groove bodies are arranged on a peripheral wall of the salient pole rotor at preset intervals and are distributed along the peripheral wall of the salient pole rotor, and a salient pole is formed between every two adjacent groove bodies; and the plurality of first conductive pieces are arranged in the groove bodies and are connected with second conductive pieces arranged at two ends of the salient pole rotor. The invention provides a high-efficiency magnetic resistance type soft starter capable of realizing automatic switching to synchronous operation after asynchronous soft start.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a reluctance type soft starter. Background technique [0002] At present, the soft starters used in the machinery industry are mainly three categories: hydraulic couplings, permanent magnet eddy current soft starters and electronic soft starters. Hydraulic coupling is a type of soft starter widely used in steel, coal, and cement industries, but it also has certain limitations, such as high installation accuracy, low transmission efficiency, and cannot be applied to low-speed transmission, large volume, and heavy weight. , There is a risk of explosion when the equipment reverses the "speeding car". The permanent magnet eddy current soft starter adopts non-contact magnetic coupling transmission, which allows a large installation error and has good vibration isolation and vibration reduction characteristics. However, there is always the problem of eddy current heati...
