An electric motor includes a rotor and a stator formed by a plurality of stator phases. The stator phases include coils that extend fully about the motor axis of the motor. The stator phases further include teeth arrayed around the motor axis. Each tooth has a tooth face oriented towards the rotor. Multiple of the lamina forming each tooth are exposed at the tooth face and are configured to extend axially and radially to the tooth face. The stator phases magnetically interact with the rotor to drive rotation of the rotor on the motor axis.

An electromagnetic machine includes a housing, an axle coupled to the housing in a rotatable fashion, a stator assembly disposed generally within the housing, the stator assembly including a stator plate and a stator bearing coupled to the axle such that the stator assembly is rotatable about the axle, a rotor assembly fixed to the axle and disposed generally within the housing and including a rotor housing that defines a circumferentially extending channel that is sized to receive a portion of the stator assembly therein; and a locking mechanism configured to selectively prevent and permit rotation of the stator assembly about the axle via the stator bearing. The housing can include an access window defined therein such that the stator assembly is accessible through the access window.

A synchronous electrical motor, which may operate poly-phase electrical power, is configured to operate at a rated flux configuration and a high flux configuration. To enable the high flux configuration, some coils wound about the stator of the electric motor can be designated bypass coils and can be selectively disconnected from the power source supplying the motor with electrical power. The remaining permanent coils continue to receive full line power and generate a rotating magnetic field with an increased magnetic flux. At startup from standstill conditions, the bypass coils are selectively disconnected so that a flux boost occurs and a corresponding increase in output torque of the electric motor.
