Iron core group of magnetic offset type linear motor

Abstract

The invention provides an iron core group of a magnetic offset type linear motor. The iron core group includes a base which is provided with a first end surface and a second end surface which backs onto the first end surface, a first iron core component which is fixedly arranged on the first end surface, and a second iron core component which is fixedly arranged on the second end surface; the base is provided with a base body; the first end surface is formed at one side base surface; a first ring-shaped positioning wall, protruding out from the first end surface, is arranged on the first end surface, and surrounds the peripheral side of the first iron core component; the first iron core component is provided with a first bottom portion which is attached to the first end surface at one side end surface, so that the peripheral side of the first iron core component can abut against the first positioning wall; and the first iron core component is also provided with a plurality of teeth which are distributed in a gridded manner and are arranged on the other side end surface of the first bottom portion and protrude out from the other side end surface of the first bottom portion. With the iron core group of the invention adopted, the efficiency of assembly and processing can be improved. The overall mechanical strength of the iron core group can be increased.

Description

technical field [0001] The invention relates to electric motors, in particular to an iron core group of a magnetic phase braking linear motor. Background technique [0002] According to the linear motor, the stator is extended linearly, and the mover is reciprocated along the linear direction of the stator. The principle is the same as that of the traditional rotary motor. Therefore, in the description, they are all expanded. Rotary motors are compared to linear motors, but the two are still different in specific technical content. For example, linear motors are divided into iron-core linear motors and iron-less linear motors because of whether they have iron cores in their composition. , there are different kinetic energy output modes between the two, which can meet different application requirements. [0003] As far as the iron-core linear motor is concerned, the iron core it has can be further divided into different tooth configurations for single-sided winding and doubl...

AI Technical Summary

Problems solved by technology

[0004] However, these technical contents for constituting the double-sided coil windings must sequentially assemble each plate-shaped tooth 1 on the base plate 5, and there are too many joint parts, so that the structural strength is not ideal, and it must be assembled one by one. Each plate-shaped tooth 1 is fixed on the base plate 5 separately. In addition to the cumbersome assembly process, special tools are required for assembly and processing, which only increases the burden on manufacturing, fails to improve manufacturing efficiency, and increases quality control. relative difficulty
