Abstract
A variable reluctance stepping motor is intended to allow a simplified control arrangement using digital techniques. The basic form consists of an 'E' type core one outer leg of which consists of a permanent magnet (14). the center leg of the 'E' carries the control winding (2) fed from an amplifier and has on its outer face a blind hole (11) serving to hold a soft iron rotor shaft (17). The rotor proper (16) again of soft iron is approximately circular fitting within the outer loop of the 'E' core. The shaft is supported by an overall nonmagnetic cover plate (12). Variations of the basic form allowing its use in different applications such as variable speed motors include breaking the classic 'E' form and including the permanent magnet in another section of the magnetic circuit.
