a rotating electromagnet

Abstract

The invention relates to a rotating electromagnet. The rotating electromagnet comprises a housing and a rotating shaft which is rotatably mounted on the housing, an armature is fixedly arranged on therotating shaft, and a coil assembly is further mounted on the housing. The armature is sleeved with baffling iron, the baffling iron is fixed relative to the housing, and the outer circumference of the armature and the inner circumference of the baffling iron are correspondingly provided with an inner toothed structure and an outer toothed structure which are radially spaced apart and circumferentially staggered from each other at a motion starting position of the armature. The rotating electromagnet further comprises a limiting structure, the limiting structure is inserted into a tooth groove between two adjacent teeth of the inner toothed structure, and baffling limiting cooperation between the limiting structure and the teeth of the inner toothed structure is achieved at a left rotating extreme position and a right rotating extreme position of the armature through the two sides of the limiting structure respectively. The rotating electromagnet further includes an elastic componentwhich provides a restoring force for the armature in a powered off state. The attraction force of the baffling iron to the armature no longer has an axial component force, and therefore the problem inthe prior art that armatures and baffling iron are attracted together and correspondingly the normal operation of rotating electromagnets is affected can be avoided.

Description

technical field [0001] The invention relates to a rotating electromagnet. Background technique [0002] In many industrial production processes, it is often necessary to use a motor with limited rotation angle or an electromagnet with limited rotation angle (such as in the process of industrial automatic sorting). At present, there are two main types of common rotating electromagnets in China: one is a rotating electromagnet similar to a motor arrangement, and permanent magnets are arranged in the housing, and the stator armature windings are arranged at intervals along the circumferential direction on the teeth of the stator. For example, the rotating electromagnet disclosed in the utility model patent with the authorized announcement number CN203910404U relies on the superposition of the radial magnetic field generated by the coil wound on the stator and the axial magnetic field generated by the permanent magnet located in the moving iron core to generate electromagnetic r...
