ABSTRACT:
Disclosed herein is a modular motor comprising a discoidal stator unit and a discoidal rotor unit rotatable about an axis of rotation under a torque established therein, the stator unit being supported by a frame arrangement and having a winding assembly within in a matrix of polymer material, the winding assembly including a number of winding elements, each of the winding elements having a pair of radially disposed portions, wherein at least one of the radially disposed portions of each winding element is spaced from a radially disposed portion of another winding element to form a cooling region therein, the cooling region being arranged for the location therein of thermally conductive materials having a thermal conductance of at least 1.5 w.multidot.cm/(cm.sup.2 .multidot..degree. C.), thereby to transfer heat from the stator unit and toward the frame arrangement during operation of the motor.
