Abstract: A bobbin wound coil for an electromagnetic coupling includes a bobbin having a cylindrical body disposed about a central axis, end flanges disposed at each axial end of the body and a terminal connector on an exterior side of one of the end flanges. The terminal connector includes a body defining a central cavity and a post extending from an exterior surface of the body of the terminal connector. A coil includes a beginning portion extending through the body of the terminal connector and the end flange on which the terminal connector is located, an end portion extending through the body of the terminal connector and the end flange, and a center portion extending between the beginning portion and the end portion and wound about the cylindrical body of the bobbin. One of the beginning portion and the end portion of the coil is wound about the post.

Abstract: A bobbin wound coil for an electromagnetic coupling includes a bobbin having a cylindrical body, end flanges disposed at opposite ends of the body and a terminal connector on an exterior side of one of the end flanges. A coil has a beginning portion extending through first openings in the terminal connector and an end flange and an end portion extending through second openings in the terminal connector an end flange. The second openings in the terminal connector and end flange are forward and rearward, respectively, of the corresponding first openings in a circumferential direction. A section of the beginning portion extends between the first openings in the terminal connector and end flange and a section of the end portion extends between the second openings in the terminal connector and end flange such that section of the end portion crosses over the section of the beginning portion.

Abstract: A bobbin wound coil for an electromagnetic coupling includes a bobbin having a cylindrical body, end flanges disposed at opposite ends of the body and a terminal connector defining a central cavity bordered, in part, by inner and outer walls and a side wall extending between the inner and outer walls. A coil has a beginning portion extending through first openings in the inner and outer walls, an end portion extending through second openings in the inner and outer walls, and a center portion wound about the bobbin body. The first and second openings in the inner wall divide the inner wall into first and second circumferential end sections and a center section. A portion of one of the circumferential end sections and the center section is spaced from the side wall to define a recess configured to receive one of the beginning and end portions of the coil.

Abstract: According to an embodiment of the invention, a drive coupling for connecting to a drive is provided. The drive coupling is adapted to removably couple a load to a power source. The drive coupling includes a body and a plurality of components. The components are operably interconnected with each other. The components have a first arrangement in which the components transmit torque from the power source to the load and a second arrangement in which the components transmit no significant torque from the power source to the load. A first of the plurality of components is adapted to translate along its center of rotation relative to a second of the plurality of components from a first position in which the components define the first arrangement to a second position in which the components define the second arrangement.

Abstract: An electric device is provided. The device includes an electric machine having a rotatable first shaft extending from an end of the machine. The device also includes a gearbox operably connected to the electric machine. The gearbox includes a first gear rotatably supported in the gearbox and a first gear connectable to the first shaft. The first gear is adapted to mesh with the second gear. The electric machine and the gearbox are adapted to drive a pump.
