Abstract
A permanent magnet rotary dynamo electric machine wherein each permanent magnet pole is equipped with a flux shunt which provides a direct flux path between the airgap at the strong tip region of the pole and the iron circuit upon which the pole is supported, the direct flux path shunting magnetic flux to the iron circuit when the current in the associated winding is low, but being saturated by flux flowing in the opposite direction at high values of winding current.
