Abstract:
In the embodiments described in the specification, a permanent magnet machine includes a stator having windings which intercept flux received from peripheral pole pieces in a rotor generated by permanent magnets disposed between the pole pieces. In order to control the flux passing through the stator windings, flux shunts are provided between the pole pieces and a winding on the core of each flux shunt generates flux in the shunt in proportion to current supplied to the winding so as to decrease the flux from the magnets which can be diverted from the pole pieces through the shunt. Current is supplied to the flux shunt windings in accordance with the instantaneous difference between the wave shape of the output from the machine and a desired wave shape stored in a control unit. An encoder supplies a signal to the control unit indicating the instantaneous position of the rotor with respect to the stator.
