ABSTRACT:
A method and apparatus for supporting a high torque, low speed electric motor suitable for mass production includes a pair of drawn steel annular frames each having an L-shaped cross section. One frame is coupled to the stator and another is coupled to the rotor. In order to provide torque pulsation isolation, at least one of the frames is coupled to its respective rotor or stator by means of an elastomeric bonding material held in compression such that radial motion is minimized while permitting limited torsional motion. One of the frames, preferably the stator support frame, may be press-fit or coupled to the stator via a hard-setting polymer or a low melting point metal such as zinc. The L-shaped frames each have a flange extending radially and which is adapted for connection to a motor frame or to a driven element.
