Additionally, there is a stator, loosely mounted around the shaft and positioned between the opposing permanent magnets, and having at least a first and second pole extending toward the first and second rotors respectively. Furthermore, there is a first and second wire coil wrapped around the first and second pole respectively to allow the formation of a first and second electromagnet respectively by passing electrical current through the first and second wire coil.

摘要： A hybrid type stepping motor includes coils located on the outer or inner periphery of stator yokes provided on a fixed shaft. This structure allows the coils to be disposed more easily and thus at a lower cost. Furthermore, it is possible to achieve a great increase in the density of winding. Auxiliary magnetic plates and auxiliary magnets are disposed at both ends of a stator yoke assembly so that a magnetic circuit is formed at both ends. According to the invention, a motor having any desired number of phases may be achieved. A magnet is disposed in each space between adjacent teeth of either a rotor or a stator or otherwise of both rotor and stator. The magnetomotive force of the magnet suppresses leakage magnetic flux and concentrates the magnetic flux within the region between the rotor and stator. As a result, in operation, an abrupt change in the magnetic flux can be obtained, which leads to an increase in the torque.

摘要： A device for field weakening in a doubly-salient variable reluctance motor having permanent magnets in the stator. The field weakening increases the constant power range of the motor and is accomplished by controlled movement of steel insets toward and away from the sides of the stator proximate the permanent magnets to provide a controllable by-pass flux path thereabout. Alternatively, the field weakening may be accomplished by a flux by-pass collar which may be angularly positioned around the stator to bridge the permanent magnets of the motor with discrete magnetic sections, thereby providing an alternate by-pass flux path around the permanent magnets in addition to the main air gap flux path. A third alternative means for maintaining a constant power range is accomplished by controlled axial sliding of the permanent magnets themselves into and out from the stator.
