Description

Technical Field

[0001] The utility model relates to the technical field of linear motors, in particular to a movable stator housing of a linear motor which is convenient to disassemble. Background Technique

[0002] At present, the structures of the existing linear motor stators in the market are generally divided into two types: one is to use solidified epoxy resin as the housing protection for the coil part of the linear motor stator; the other is to use an aluminum or other non-magnetic material housing for the coil part of the linear motor stator as the protective cover for the motor stator coil part.

[0003] In the prior art, the linear motor stator is composed of multiple groups of parts. The protective shell cannot install and protect multiple groups of parts. The disassembly steps of the existing stator protective shell are complex, and the difficulty of maintenance and replacement is also relatively large. Therefore, we propose a movable stator housing of a linear motor which is convenient to disassemble. Content of the Utility Model
