Patent ID: 8198778

Claim:
A method for manufacturing a rotary actuator comprising: providing an outer enclosure; positioning a stator assembly within the outer enclosure, the stator assembly comprising a plurality of stator laminations each having a lamination face oriented orthogonally to a centerline axis of the rotary actuator, with each of the stator laminations consisting of two oppositely positioned pole faces; and positioning a rotor assembly adjacent to the stator assembly such that the two poles faces are separated from the rotor assembly by a working air gap to allow for the rotor assembly to rotate about the centerline axis of the rotary actuator, the rotor assembly including a rotor core and a plurality of rotor laminations press-fit onto the rotor core; wherein each of the outer enclosure, the stator assembly, and the rotor assembly are arranged to carry a magnetic flux therethrough, with each of the plurality of stator laminations being configured to carry the magnetic flux therethrough in a direction parallel to the lamination face of the stator lamination; and wherein each of the plurality of rotor laminations consists of a pair of faces aligned with the pole faces of each of the plurality of stator laminations, such that the rotor assembly is caused to rotate relative to the stator assembly within a pre-determined range of rotation that is less than 360 degrees.
