Title: Synchronous motor of facing type
Inventor: SUZUKI YASUO
IPC: H02K7/08
Filed: 1977-10-31
Abstract: PURPOSE: To ensure suitable friction between thrust washer and bearing and permit reliable start and steady rotation by having a central portion of the surface of the thrust washer in contact with the bearing depressed compared to the edge.  
     CONSTITUTION: A rotor 1 provided on one side with an annularly and alternately magnetized disc-like magnet 2 has its center shaft 3 supported by a bearing 4, and a stator pole plate 7 magnetized by an exciting coil 6 faces the rotor 1. A thrust waster 8 is mounted on the central shaft 3. Although its side in contact with the rotor 1 is flat, its side facing the bearing 4 has a concave conical surface with a central portion depressed with respect to the edge by, for instance, 10 to 30μ. With this construction, with the rotation of the rotor 1 accompanying the excitation of the stator pole plate 7 the thrust washer 8 is gradually worn from the edge of the surface facing the bearing 4. Thus, it is possible to prevent wide reduction of wear of the thrust washer in the short period of time due to generation of a gap in the edge.
