| 20110285332 | CONTROLLER FOR ELECTRICAL MACHINES - The present invention relates to control of electrical machines and in particular, though not exclusively, to control of synchronous machines such as hybrid stepping motors, flux switching machines and brushless permanent magnet motors and generators. A sensorless control system for an electrical machine is provided comprising a rotor, a stator having one or more phase windings for generating a rotating stator magnetic field, the system comprising detection means for monitoring the currents in the phase windings providing a real component I | 11-24-2011 |
| 20110181135 | MICRO-STEPPING RELUCTANCE MOTOR - 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. | 07-28-2011 |
