A method of operating an electric or hybrid system comprising a synchronous reluctance electric motor coupled to an electric or hybrid powertrain is described herein. The method comprises determining (i) a torque demand required of the electric motor and (ii) a speed of rotation of the rotor of the electric motor, and storing kinetic energy in a rotor of the electric motor from the powertrain in response to at least one of (i) the determined torque demand falling below a selected torque demand threshold and (ii) the speed of the rotor being below a selected rotor speed threshold. The method further comprises operating the electric motor by powering the electric motor with electricity to deliver energy to the powertrain in response to at least one of: (i) the determined torque demand rising above a selected torque demand threshold and (ii) the speed of the rotor falling below a selected rotor speed threshold.
A system for delivering energy to, and storing energy from, an electric or hybrid powertrain, the system comprising:
A method of operating an electric or hybrid system comprising a synchronous reluctance electric motor coupled to an electric or hybrid powertrain, the method comprising:
A rotor for a synchronous reluctance electric motor comprising no permanent magnets and a plurality of magnetic flux guides supported by a flux guide support, wherein the plurality of magnetic flux guides are configured to preferentially guide the flow of magnetic flux therethrough.
