Document Type and Number:
Japanese Patent JP2018143081
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a motor that make drive sound of the motor silent by bringing a wheel and a center shaft into a non-contact state.SOLUTION: Permanent magnets are arranged so as to repel each other in a wheel part and at respective places of a center shaft, and the wheel and the center shaft built therein are completely floating and do not contact each other. The permanent magnets (F) arranged within the wheel and at the respective places of the center shaft so as to repel each other have an inverted V-shape or a V-shape in order to prevent shaking due to repulsion of the magnets. Two rings (or three rings or more) of electromagnets in which electromagnets individually controlled electronically are arrayed within the structure are arranged on the wheel side or center shaft side. By switching between the S pole and the N pole of electronically-controlled electromagnets, the wheel part or center shaft in which the rings of the permanent magnets are arranged is controlled rotationally.SELECTED DRAWING: Figure 1
