摘要： A method for installing a rotor of an electrical machine is disclosed. The method comprises using axially directed guide bars (107-109) for keeping the rotor (102) centered with respect to a bore of a stator (101) during the installation of the rotor. The rotor has sliding surfaces so that it can be slid in the axial direction to its final position along the guide bars. The mechanical support structure (104) that supports bearings (105, 106) of the rotor are provided with supporting surfaces for being able to give mechanical support to the guide bars. The mechanical support structure (104) may comprise for example threaded holes to which threaded ends of the guide bars can be tightened. After the rotor has been moved to its final position and it is supported by the bearings, the guide bars are removed.

摘要： An electric linear displacement motor for use in a testing apparatus includes a stator assembly having a stator housing and a plurality of coils within the stator housing. An armature is positioned within the stator housing and includes a plurality of magnets along a length of the armature. A bearing assembly is attached to the first end of the stator housing and includes a bearing housing containing a bearing. A first end portion of the armature engages and is carried by the bearing. A brake assembly is coupled to the first end of the armature and the bearing housing. The brake assembly includes a moving portion coupled to the armature and a non-moving portion coupled to the bearing housing wherein the moving portion has less mass than the non-moving portion and therefore reduces the moving mass of the armature.

摘要： A pressurized gas cooled high speed motor includes a wound stator and rotor assembly disposed within a pressure vessel such that the stator and rotor assembly can be removed without disconnecting the high pressure lines to the pressure vessel. The stator has a spring loaded axial retention mechanism that cooperates with a concentric groove in the pressure vessel for maintaining the stator and rotor assembly fixedly in place in the pressure vessel during transport and operation of the motor. A shoulder formed in the pressure vessel is used to axially position the stator assembly within the pressure vessel. A key if provided for angularly and fixedly positioning the stator within the pressure vessel.

摘要： A driving unit includes a stator, a housing including a tubular section to accommodate the stator, a cover coupled to the housing to block an upper opening of the tubular section, and a bent wire rod defined by a wire to press the stator against the tubular section, the bent wire rod being arranged between a top surface of the stator and a rear surface of the cover while being compressingly deformed along an axis of the stator. The bent wire rod has an annular or substantially annular shape with an opened portion when seen along the axis, and includes projections projecting upward along the axis and depressions projecting downward along the axis being arranged alternately and successively. An elastic force from the bent wire rod causes the stator to receive a downward force along the axis. The stator is pressed against the tubular section to hold the stator in the housing.
