Title:
AXIAL GAP MOTOR
Document Type and Number:
WIPO Patent Application WO/2003/065549
Kind Code:
A1
Abstract:
An axial gap motor comprises a base (10), a shaft (14), a stator frame (12), electromagnet units (19), bearings (11A, 11B), a rotor frame (13) disposed at a predetermined distance from the stator frame (12), permanent magnet units (18) opposite to the electromagnet units (19) with a predetermined axial gap, a rotary encoder (17), and a drive unit (22) for supplying an excitation current to the electromagnet units (19) according to the output of this rotary encoder (17) so that the magnetic pole of the electromagnet unit (19) and that of the permanent magnet unit (18) electromagnetically repel each other. The field center line passing through the pole center of the electromagnet unit (19) crosses the field center line passing through the pole center of the permanent magnet unit (18) at a predetermined angle.
