  • Patent number: 9343930
    Abstract: A stator has a plurality of segments connected with connectors to define a core for the stator. Each of the segments comprises a plurality of laminations arranged side by side forming a lamination stack with axially opposite sides. The lamination stack has an end cap abutting an axial side of the lamination stack. The end cap has first and second posts extending axially therefrom. At least one of the posts defines a wire path for wire wound around the stack. Each of the connectors comprises a bridge portion. The bridge portion has openings dimensioned to receive the posts in a manner that the connector is removably attachable to the post of the end cap of a segment and the post of the end cap of an adjacent segment. The connector has an insulator portion projecting from the bridge portion. The insulator portion extends between adjacent segments.

  • Publication number: 20080191564
    Abstract: An integrated motor and drive assembly includes a motor, a fan, and a drive unit. The motor is responsive to at least one drive signal. The fan is axially aligned with the motor and operable to generate a cooling flow. The drive unit is axially aligned with the fan and operable to generate the drive signal. The cooling flow traverses the motor and the drive unit.

  • Patent number: 6223504
    Abstract: A base plate for a package to inhibit an object's inadvertent displacement when the plate and object are positioned within a shipping container. The plate is composed of a rectangular sheet of paperboard or sheet form material folded at least once, and preferably twice, both horizontally and vertically to form multiple sheets in superimposed, overlapping relation thereby creating a support or base plate. A longitudinally extending separation in the upper of the sheet form supports include a plurality of separations extending from opposite edges of the longitudinal separation to form cantilevered tabs extending from opposite sides of the separation. A recess in the lower sheet form support underlying the longitudinally extending separation permits deflection of the tabs into the recess when an object, such as a motor, is placed thereon to thereby partially capture, cradle and cushion the object upon the support plate.

  • Patent number: 5763969
    Abstract: An integrated motor drive system includes a variable speed electric motor, a fan connected to the electric motor to generate an air flow as the motor rotates, and a motor drive connected to the electric motor, the drive including a heat sink disposed between the motor and the drive and having a plurality of asymmetrically spaced apart heat transfer fins transferring heat generated by power components in the drive to the air flow. The fan is connected to a one of either the rotor of the variable speed motor or to an auxiliary fan motor controlled independently of the variable speed motor. A fan shroud on one end of the motor acts as an air duct member adapted for dividing and directing the flow of air from the fan to sets of heat transfer fins on the heat sink. A method of operating the drive integrated type motor system includes generating motor speed command signals in the drive based on inputs from an operator through an operator interaface unit on the drive.

  • Patent number: 5747904
    Abstract: A moisture drain plug for use with a cylindrical motor housing provides a plurality of diverse drainage pathways to promote the egress of moisture from within the housing. The plurality of diverse drainage pathways includes a first set of primary moisture egress pathways and a second set of secondary moisture egress pathways. Should one or more of the primary moisture egress pathways become clogged, the secondary moisture egress pathways provide for more than adequate drainage from the motor housing.
