A motor 200, particularly for a handwheel actuator of a dual motor steer-by-wire system, comprises a stator 202 and a rotor 201, the stator carrying a plurality of phase windings and the rotor carrying a plurality of magnet poles. Stator 202 comprises a stack of laminations, each comprising a ferromagnetic plate and at least one hole, preferably three holes, within the plate aligned with a corresponding hole in adjacent plates in the stack. Motor 200 also comprises at least one electrically conductive pin 204 extending axially along a length of stator 202 passing through the aligned holes to provide a path for currents axially along the stator. Pins 204 may have an interference fit and may be deformed at one or both ends to act as a rivet. The effective loss in the stator, excluding copper windings, may be at least 30 W/kg. A mechanical assembly and a construction method are also provided.
