Abstract
Electric motors having variable poles are disclosed herein. In one aspect, an electric motor includes a stator including a plurality of magnetic conductive wires. The magnetic conductive wires are configured to form a plurality of poles. The electric motor further includes a rotor configured to rotate in response to a magnetic field generated by the poles of the stator and an electronic control module electrically coupled to the magnetic conductive wires. The electronic control module is configured to adjust a configuration of the poles of the stator.
