This inverter-integrated electric compressor is configured such that a P-N terminal for inputting high-voltage DC power is provided on a main circuit board, a power source-side cable can be connected to said P-N terminal by inserting a connector provided on one end, a high-voltage electric component configuring the inverter device is arranged in the facing position on the side of the main circuit board opposite that of the P-N terminal, and the electric component is housed in a case and fixed by a resin member; and is further configured such that multiple protruding and receding portions are formed on the edge of the top opening of the case, and stress on the main circuit board when the connector is plugged in is received by the protruding portions abutting against the bottom surface of the main circuit board. | 2015-12-03 |
20150349614 | EXPANDING GAP SUPPORT FOR ELECTRIC MOTOR ASSEMBLY - A number of variations may include a product comprising a gap support tool comprising an inflatable body portion, wherein the inflatable body portion comprises a plurality of fluid chambers, and wherein the plurality of fluid chambers are constructed and arranged to center a rotor inside a stator and create a concentric air gap between the stator and the rotor during assembly. | 2015-12-03 |
20150349615 | Method of Constructing a Rotor for a Line Start Interior Permanent Magnet Motor - A method includes: (1) providing a rotor for a line start interior permanent magnet motor wherein the rotor has rotor bars slots extending axially along a length of the rotor configured to receive rotor bar material, and magnet slots extending axially along a length of the rotor configured to receive magnetic material; (2) disposing rotor bar material in the rotor bar slots; (3) arranging a first end member on an axial end of the rotor; (4) disposing magnetic material in the magnet slots; (5) magnetizing the magnetic material; and (6) arranging a second end member on the rotor opposite the first end member. The step of arranging the second end member on the rotor occurs after magnetizing the magnetic material. | 2015-12-03 |
