Title:
SINGLE-WINDING POLE-CHANGE MOTOR
Document Type and Number:
Japanese Patent JPH05137301
Kind Code:
A
Abstract:
PURPOSE: To obtain a single-winding pole-change motor, in which a high starting torque is obtained on the side of a low speed and a power factor can be improved on the low speed side and at the time of a low load.
CONSTITUTION: Leands 14-19 are led out from the both ends and middle parts of respective phase stator windings 11-13 of a single-winding pole-change motor and power is switched from one connection to another by a cross board 5 so that it is made possible to properly use a Δ-connection at starting on the side of a low speed and a Y-connection in operation on the low-speed side.
