Abstract: A system for controlling pitch angle of a blade of a wind turbine is provided. The system may comprise a switched reluctance motor and an inverter. The motor may be configured to be positioned at a hub of the wind turbine and coupled to the blade. The motor may have a stator and a rotor. The stator may have: (i) multiple stator poles and (ii) coil windings around each of the multiple stator poles. The rotor may be rotatably mounted with respect to the stator. The rotor may have multiple rotor poles and a rotor shaft configured to be coupled to the blade to control the pitch angle of the blade. The inverter may be configured to supply electrical power to the coil windings to control motion of the rotor shaft in response to receiving a pitch angle control signal from a pitch angle control system of the wind turbine.

Abstract: A three-phase switched reluctance machine has a rotor, a first stator and a second stator. The rotor, first stator and second stator are coaxially and concentrically disposed. The rotor and both the first stator and second stator have corresponding poles. Only one of the stators has coils wound about its poles, while the other stator does not have any coils. A defined relationship between the number of rotor poles, the number of stator poles on the first stator and the number of stator poles on the second stator may improve the torque quality of the switched reluctance machine.

Abstract: A switched reluctance machine has a stator core salient with stator poles disposed concentrically with a rotor that is salient with rotor poles. A plurality of coil windings are wound about the stator core so that a pair of windings are adjacent each of the stator poles. The pair of coil windings induces magnetic flux in the adjacent stator poles and the rotor rotates to align the rotor poles with the stator poles having the induced magnetic flux. The rotor is rotatable at high speeds of up to 50,000 RPM and the coil windings can be directly cooled.

Abstract: Electric generators are described herein. The electric generators include an interior machine formed of an interior rotor and an interior portion of a stator, and an exterior machine substantially concentric to the interior machine. The exterior machine includes: an exterior rotor substantially concentric to the interior rotor, and an exterior portion of the stator. Each of the interior machine and the external machine are driven by an engine to produce a respective current. The described electric generators can be used in diesel electric locomotives.
