Title:
VARIABLE GAP MOTOR
Document Type and Number:
Japanese Patent JP2022166721
Kind Code:
A
Abstract:
To provide a highly energy efficient variable gap motor.SOLUTION: A variable gap motor 10 includes an annular field stator 14 having a plurality of salient stator poles 22 arranged at predetermined intervals in the circumferential direction and wound with field coils 24 for energizing each phase of a multiphase current, and an annular mover 16 made of a ferromagnetic material, which is arranged radially inward of the field stator so as to be non-rotatable and relatively rockable with respect to the field stator. A radial gap between the tip surface of the salient stator pole and the tip surface of the salient mover pole facing each other in the direction of the radial electromagnetic force acting to approach the salient stator pole 22 and the salient mover pole 26 by energizing the field coil is 1 mm or less.SELECTED DRAWING: Figure 1
