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.
