Title:
RELUCTANCE MOTOR
Document Type and Number:
WIPO Patent Application WO/2019/098278
Kind Code:
A1
Abstract:
[Problem] To achieve a reduction in the noise, size, and cost of a reluctance motor. [Solution] Prioritizing one-way rotation and one-way torque in particular, a change is induced in the partial shape of magnetic poles on the rotor of a reluctance motor in the direction of forward movement, or magnetic resistance is increased, the torque generation range of each phase is expanded, and the increase/decrease time of an electric current is ensured to reduce the noise. With the relative increase in copper losses due to this drive method, copper losses are reduced for a full-pitch wound winding, and harmful effects from the problem of over-voltage generated in the full-pitch wound winding are reduced by a drive method in which the over-voltage is canceled out.
