Title:
Rotation electrical machinery
Document Type and Number:
Japanese Patent JP6210161
Kind Code:
B2
Abstract:
Provided is a rotating electrical machine that has superior rotor strength and can be manufactured at low cost, wherein torque generated by a rotor can be increased. Two holes are formed in a circumferential direction in each pole in a rotor. The two holes communicate with an outer periphery of the rotor, and an outer peripheral edge portion on an outer side in a radial direction of the rotor of the two holes is connected via a center bridge between the two holes to a core portion on an inner side in the radial direction of the rotor in each pole. The center bridge is demagnetized, or the permeability thereof is reduced. Consequently, leakage flux passing through the center bridge can be reduced, even when the width of the center bridge is increased.
