Production process of permanent magnet stepping motor

Abstract

The invention discloses a production technology of a permanent-magnet stepper motor. The method comprises the steps of (a) preparing a rotor and a stator; (b) carrying out laminated positioning on the axial outer end surfaces of an upper middle pole plate and a lower middle pole plate in cooperation with a laminated positioning structure through the laminated positioning structure; (c) assembling corresponding coil assemblies on middle pole plate pole claw groups of the corresponding middle pole plates and connecting outlet boxes and the coil assemblies; (d) assembling an upper case on the upper middle pole plate, ensuring that the upper middle pole plate is matched in a rabbet part of the upper case and a protruding part of the upper middle pole plate is clamped in a gap of the upper case; (e) making a short-axis extension end part of the rotor pass through an upper pole claw support part, supporting the short-axis extension end part on the upper case and then assembling a lower case; and (f) welding a contact part between the axial outer end surface of an open end of the lower case and the axial outer end surface of the open end of the upper case. By the production technology, the assembly accuracy can be improved; the performance of the motor is improved; the production efficiency can be improved; and massive production is facilitated.

Description

technical field [0001] The invention relates to a production process of a permanent magnet stepping motor. Background technique [0002] At present, in the production process of the original BY series stepping motor, every time a part or component is processed, it needs to be transferred to a fixed location for warehousing inspection. In mass production, this kind of processing and operation will consume a lot of time, which will seriously affect the production efficiency. If this production mode is adopted in the enterprise, even if it does not affect the delivery time, it is often easy to produce a lot of bad products. Therefore, effectively improving production efficiency in the production process is what people have been pursuing. SUMMARY OF THE INVENTION [0003] The invention aims to solve the defects of cumbersome process and low production efficiency in the production process, and provides a production process of a permanent magnet stepping motor, which can not on...
