An Axial Air-AP Reluctance Motor for Variable Speed Applications

The disc motor is a brushless, reluctance-principle; rotating machine that has been developed to the prototype stage for traction and variable speed drive application. It is attractive for these and other applications because of a simple magnetic structure which has potential for very low assembly costs, and because it can be controlled over a wide range of speed and torque by thyristor circuits of comparable simplicity to the chopper circuit used with do traction motors. The motor theory is briefly discussed and laboratory measurements of machine performance is presented.
