ABSTRACT:
An electric motor comprising a stator and a rotor rotatably mounted in a stator cavity. The stator is made from at least two stator sections and each section comprises a plurality of axially directed generally semi-cylindrical sheet metal laminations having axial edges which are directed inwardly to form the rotor cavity and having the area between said edges surrounded by a stator coil. Each stator part has at its axial ends a radially directed plate member including a series of axially extending spaced teeth which project and engage between the edges of the sheet metal laminations adjacent the plate member to maintain the laminations in predetermined spaced relation to allow passage of cooling medium through the stator coil.
