Electric motor and handwheel actuator assembly incoporating a motor

A mechanical assembly comprising:

• a housing;
• a shaft rotatably mounted with respect to the housing;
• one or more motors each having a stator and a rotor, the stator carrying a plurality of phase windings and the rotor carrying a plurality of magnet poles and being connected to the shaft;
• a control circuit adapted to control the current flowing into or out of the or each motor to cause a net torque to be applied to the shaft during normal operation, and
• in which the stator of at least one of the motors comprises a ferromagnetic material defining a yoke and a plurality of teeth and further comprising at least one band of electrically conductive material that encompasses at least a portion of one of the teeth or encompasses at least a portion of the yoke in a region between adjacent teeth and is in direct contact with the tooth, and in which the band provides an electrical path between the band and the portion of the tooth or yoke and in which the band wraps around upper and lower end regions of the portion of the tooth or yoke and extends axially down the opposing side faces of the tooth or yoke, and in which the band is isolated from the control circuit so that it cannot receive current from or cause a flow of current to any external source of current.
