Document Type and Number:
WIPO Patent Application WO/2018/180379
Kind Code:
A1
Abstract:
The present invention comprises: a surface magnet-type rotor (14) having a plurality of permanent magnets (15) fixed to the inner peripheral surface thereof; wedge-shaped projections (42) for fixing the permanent magnets (15) to the rotor (14); and a stator (30) that is disposed on the inside of the rotor (14) and that has teeth (35) and grooves (36) formed alternately on the outer periphery thereof. The number of the permanent magnets (15) is 32, and the number of the grooves (36) is 24. In the cross-section shape of the permanent magnets (15) in a direction orthogonal to the rotation axis of the rotor (14), a chamfer (43) is formed on both sides so as to avoid the concentration of magnetic flux, and the stator (30) side has a convex shape.
