AI Technical Summary

Technical Problem

The existing motor winding binding wire is located at the rear of the motor, which causes the coil to occupy the space of the housing. The housing needs to be lengthened to accommodate the coil, resulting in a longer overall motor length and increased material costs.

Method used

By adopting a stator winding binding method, the coil is placed in the accommodating cavity of the front cover, and the lead wire is guided to the rear end through the guide groove. By utilizing the remaining space of the front cover and combining the design of the annular groove segment and slot hole, a compact motor structure is achieved.

Benefits of technology

It effectively shortens the overall length of the motor, reduces material consumption and lowers costs, while ensuring smooth lead-out of the lead wires and avoiding installation difficulties.

Abstract

This invention provides an electric motor, belonging to the field of electric motor technology. It includes a housing with a front cover mounting end and a rear cover mounting end. A front cover is mounted on the front cover mounting end, and a rear cover is mounted on the rear cover mounting end. The front cover, housing, and rear cover form a receiving chamber. A wire outlet hole is provided on the side of the housing near the rear cover. A stator winding and a rotor passing through the stator winding are installed in the receiving chamber. The stator winding and rotor divide the receiving chamber into a first chamber and a second chamber. The first chamber is formed on the side near the front cover and is configured to house the coil. The second chamber is formed on the side near the rear cover and is configured as a brake. The coil has a lead wire. A guide groove is also provided on the housing, configured to guide the lead wire from the coil in the first chamber to the second chamber and out through the wire outlet hole on the housing. This invention effectively shortens the overall length of the electric motor, reduces material consumption, and lowers costs.
