Permanent Magnet for Low Eddy-Current Loss of Permanent Magnet Motor and Permanent Magnet Motor

Abstract

Some embodiments of the present disclosure provide a permanent magnet for low eddy-current loss of a permanent magnet motor and a permanent magnet motor. The permanent magnet includes a first magnetic pole surface, a second magnetic pole surface, four side surfaces, and a plurality of embedded electrical insulation layers. The first magnetic pole surface is basically orthogonal to a magnetization direction of the permanent magnet. The second magnetic pole surface is parallel to the first magnetic pole surface. The plurality of embedded electrical insulation layers are parallel to the magnetization direction of the permanent magnet; and at least one edge of each embedded electrical insulation layer is neither parallel nor perpendicular to the magnetization direction of the permanent magnet.
