Title:
MOTOR AND CONTROL DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/031698
Kind Code:
A1
Abstract:
[Problem] To reduce the size and cost of a motor and a control device. [Solution] The present invention relates to a motor for appropriately supplying one-way current to each of winding wires, and a circuit for driving the motor. Two full-pitch winding wires Wab and Wca, respectively disposed adjacent to each side of an A-phase stator magnetic pole, and driving transistors are connected to each other in series to supply A-phase current component Ia, an A-phase magnetic flux component φa passing through the A-phase stator magnetic pole is excited to generate torque, and the other phases are configured in the same manner. As a result, each of the stator magnetic poles can be selectively excited, and the voltages at both ends of the series winding wire are reduced to the corresponding magnetic flux, thus simplifying and improving the performance of the motor. In addition, since each of the winding wires and each of the transistors can be commonly used in two phases, the utilization rate can be improved, and size and cost reductions can be achieved.
