Abstract: A variable reluctance electric motor is disclosed. The motor has a generally circularly shaped stator core having at least one pole and a winding disposed thereon. Furthermore, the motor has a rotor core with at least one rotor lobe and configured to be insertable into the stator core. A gap is defined between the stator core and rotor core. The radius of the rotor core is configured to vary the length of the gap between the rotor lobe(s) and the stator pole(s) when rotating within the stator core in order to create a variable reluctance machine.

Abstract: An electromagnetic motor with increased torque. The motor has a rotor coil configured to generate a magnetic field. At least two stator coils are connected in series with the rotor coil. Each of the stator coils is configured to generate a respective magnetic field. The motor further includes a plurality of switches configured to generate the magnetic field in each of the respective rotor and stator coils. The switches are configured to generate the magnetic field in the stator coils such that the rotor coil rotates in response thereto. By having the rotor and stator coils connected in series, the torque of the motor is increased.
