Abstract:
An assembling apparatus for a permanent field magnet, rotating electrical machine having a generally cylindrical stator case with permanent field magnets secured to an inside cylindrical surface of the stator case and a rotor that is journalled by paired front and rear end closures attached to the stator case, said assembling apparatus comprising a fixture for assembling and holding one of the end closures with one end of the rotor journalled therein, a rotor holder smaller than the inside cylindrical surface of the stator for holding the other end of the rotor in alignment with the rotational axis of the rotor defined by the held one end closure, and a stator case holder for holding the stator case and supported for movement along the rotor axis while holding the stator case, and a driver for assembling the stator case to said one of the end closures by relatively moving said stator case holder along the rotor axis while holding the other end of the rotor with the rotor holder.
