| 20100133945 | SEGMENTED STATOR CORE WINDING APPARATUS AND METHOD OF WINDING A SEGMENTED STATOR CORE - A winding apparatus for a segmented core having a plurality of stator teeth includes a mounting fixture configured to support select ones of the plurality of stator teeth. The mounting fixture is configured to rotate about an axis defined by each of the plurality of stator teeth. The winding apparatus also includes a plurality of stator tooth holding elements operatively connected to the mounting fixture. Each of the plurality of stator tooth holding elements are configured to retain a select one of the plurality of a stator teeth relative to the mounting fixture. The mounting fixture is selectively rotated about the axis of at least one of the plurality of teeth to apply wraps of wire to the one of the plurality of stator teeth while at the same time rotating others of the plurality of stator teeth that have already been wrapped with wire. | 06-03-2010 |
| 20100139896 | LIQUID COOLED STATOR TERMINAL BLOCK FOR AN ELECTRIC MACHINE - An electric machine including a housing having an outer surface and an inner surface that defines an interior portion. The housing includes a connection zone. A fluid circuit passes, at least in part, through the housing. The fluid circuit includes an inlet portion and an outlet portion. A stator assembly is arranged within the interior portion of the housing. The stator assembly includes at least one connector lead, and a terminal block extending through the housing. The terminal block includes a non-electrically conductive member that is sealed against the housing. The non-electrically conductive member includes a fluid cavity. At least one electrically conductive member is covered, at least in part, by the non-electrically conductive member. The fluid cavity guides a fluid along a portion of the at least one electrically conductive member to absorb heat. | 06-10-2010 |
| 20100253164 | STATOR ASSEMBLY INCLUDING A TERMINAL BLOCK FOR AN ELECTRIC MACHINE - An electric machine includes a housing having an outer surface and an inner surface that defines an interior portion. The housing also includes a connection zone having a first end portion that extends from the outer surface to a second end portion that is exposed to the interior portion. The connection zone includes a connection passage. A terminal block extends through the connection passage. The terminal block includes a non-electrically conductive member that is sealed against the connection passage, and an electrically conductive member covered by the non-electrically conductive member. The electrically conductive member includes a first end section that extends to a second end section through an intermediate section. The first end section has a first connection zone and the second end section has a second connection zone. The second connection zone is at an angle relative to the first connection zone. | 10-07-2010 |
| 20110072652 | METHOD OF WINDING A PLURALITY OF STATOR TEETH OF A SEGMENTED STATOR CORE - A winding apparatus includes a mounting fixture configured to support a plurality of stator teeth. The mounting fixture is configured to rotate about an axis defined by each of the plurality of stator teeth. A plurality of stator tooth holding elements are connected to the mounting fixture. The plurality of stator tooth holding elements retain a select one of the plurality of stator teeth relative to the mounting fixture. The mounting fixture is selectively rotated about the central axis of at least one of the plurality of teeth to apply wraps of wire to the one of the plurality of stator teeth while at the same time rotating others of the plurality of stator teeth. A wire guiding member is supported by the mounting fixture. The wire guiding member is configured and disposed to establish a desired length of wire between adjacent ones of the plurality of stator teeth. | 03-31-2011 |
| 20110114399 | TRACTION MOTOR AND PLANETARY GEAR ASSEMBLY - A vehicle includes a chassis, a traction member associated with the chassis, and a drive system associated with the chassis and the traction member comprising an electric traction motor, a planetary gear assembly coupled to the electric traction motor, the planetary gear assembly comprising an output member coupled to the traction member, wherein rotation of the output member provides a drive torque for the traction member. | 05-19-2011 |
| 20110115320 | REVERSIBLE PLANETARY GEAR ASSEMBLY - A planetary gear assembly includes a ring gear configured for connection to a rotor of an electric motor when in a first position and configured for connection to a housing of the electric motor when in a second position, a sun gear configured for connection to the housing when the ring gear is in the first position and configured for connection to the rotor when the ring gear is in the second position, and a plurality of planet gears configured to mesh with the ring gear and the sun gear. | 05-19-2011 |
| 20110115321 | ELECTRIC MOTOR AND PLANETARY GEAR ASSEMBLY - An electric motor assembly includes a stator defining a first interior space, a rotor positioned within the first interior space and configured for rotation relative to the stator, the rotor defining a second interior space, and a planetary gear assembly associated with the rotor and at least partially positioned within the second interior space. | 05-19-2011 |
| 20110148243 | STATOR CORE FOR AN ELECTRIC MACHINE - A stator includes a body portion having an outer portion and an inner portion that defines an interior region, a plurality of stator teeth members extending from the inner portion into the interior region, and at least one continuous conductor wound around select ones of the plurality of stator teeth members to form at least one pole. Each of the plurality of stator teeth members including a number of wraps of the at least one continuous conductor. The at least one continuous conductor including a number of twists that is fewer than the number of wraps. | 06-23-2011 |
