Abstract

The invention provides a magnetic isolation method for a permanent magnet motor, which belongs to the technical field of motors, and includes opening a plurality of mounting hole groups on the outer surface of the rotor bracket; Magnetic isolation patch; the magnetic isolation patch is arranged around the outer periphery of the rotor bracket; and the magnetic isolation patch and the rotor bracket are fixedly connected through the cooperation of the fastener and the mounting hole; the magnetic isolation patch is distributed on the outer periphery of the rotor bracket to form a Magnetic isolation area. In the magnetic isolation method of the permanent magnet motor provided by the present invention, installing the magnetic isolation patch on the rotor bracket can be adjusted according to the distance between the magnetic pole mounting bolts, and has strong versatility; at the same time, installing the magnetic isolation patch in this way can ensure the magnetic isolation The magnetic isolation effect of the patch can also ensure the smooth progress of subsequent functions.

Description

technical field [0001] The invention belongs to the technical field of motors, and more specifically relates to a magnetic isolation method for permanent magnet motors. Background technique [0002] An isolation structure needs to be provided on the outside of the rotor to prevent magnetic flux leakage. At present, aluminum or other non-magnetic materials are integrally cast on the surface of the rotor bracket. This method has problems such as casting process, complicated tooling, difficult processing, long construction period, and high cost. Another way is to install the magnetic isolation strip axially. The magnetic isolation strip needs to be changed according to the length of the iron core and the position of the magnetic pole hole. , It is easy to have the problem of two magnetic pole cores, one high and one low, and the installation of the magnetic steel is difficult. At the same time, the magnetic steel is not uniformly stressed in the groove, and the reliability is ...
