MICRO-STEPPING RELUCTANCE MOTOR

摘要

The present invention relates to control of electrical motors and in particular, to the design and control of reluctance motors capable of micro-stepping position control. According to the invention there is provided a single stack variable reluctance machine with salient stator teeth and salient rotor teeth, the stator further comprising field magnet sections created by either permanent magnets or field windings or a combination of permanent magnets and field windings, and further comprising armature windings connected to form at least two armature phase windings, the armature phase windings connected to a power source or power electronic inverter for the supply of positive and negative current to at least two armature phase windings such that the rotor rotates in small incremental steps in response to small changes in the current in one or more of the phase windings.
