A New Design Principle for Pole-Changing Winding-the Three-Equation Principle

The article substantiates the relevance of the development of pole-changing windings for turbo-engins. There is a review of specialized literature on the development of pole-changing windings. Two-speed motors with a 4/3 pole number ratio have one pole-changing stator winding by the method of PAM. Based on the method of “Discretely specified spatial function” a pole-changing winding is obtained for a 3/4 pole ratio with 72 stator slots. The analysis of the electromagnetic properties of the obtained winding is carried out. The correspondence of the obtained winding for use in turbo-mechanisms is revealed. As a result of the study, there were procured the stator windings at 6 and 8 poles, which enabled to change the spin speed of the motor in the fan drives without breaking the drive power circuit by the scheme ΥΥΥ/ΥΥΥ with additional branches
