A rotor assembly for an electric motor includes a rotor core that is fabricated from a plurality of stacked laminations. The rotor core has a plurality of arcuately arranged, axially extending magnet receiving slots. The rotor core includes a plurality of magnets received in respective ones of the magnet receiving slots. The laminations include radially extending deflectable magnet retaining tabs that extend into the magnet receiving slots. The magnet retaining tabs engage and are deflected by a corresponding one of the magnets to exert a reactive force against the magnets.

A set of interchangeably pairable end caps is provided for electrically insulating a variety of stator cores having differing axial stack heights. Each pair of end caps cooperatively defines a generally radially projecting, generally axially extending wire barrier including axially opposed ends. Each of the ends forms a respective rounded winding ramp configured to smoothly guide wiring into a wire trough in part defined by the wire barrier.

Overlapped end caps for stator core

A motor includes a shaft rotatable about an axis, an engaged component engaged by the shaft, a sleeve fixed to the shaft to rotate therewith, and a seal at least partly circumscribing the shaft. The shaft includes an engagement region presenting a substantially variable outer shaft surface that at least in part engages the engaged component. The sleeve includes a first section that at least partly circumscribes and engages the engagement region of the shaft. The first section of the sleeve presents an outer seal-engaging surface and an outer bearing-engaging surface. The seal and the bearing each at least partly circumscribe the engagement region of the shaft and the first section of the sleeve to engage the seal-engaging surface and the bearing-engaging surfaces, respectively, of the sleeve.

Sealing sleeve for geared shaft of gearmotor assembly

A motor includes a housing, a shaft, a bearing, a bearing plate, and a seal. The housing includes first and second housing components directly engaging one another along a housing interface. The housing at least in part defines a sealed chamber. The shaft is at least in part received in the chamber. The bearing rotatably supports the shaft. The bearing plate is enclosed within the housing. The bearing plate supports the bearing within the housing. The seal is disposed along the housing interface. The bearing plate is spaced inwardly from the housing interface and the seal.

Internal bearing plate for gearmotor assembly

Electric motors are disclosed. The motors are preferably for use in an automated vehicle, although any one or more of a variety of motor uses are suitable. The motors include lift, turntable, and locomotion motors.

Staked rotor core for retaining magnets

A motor includes a housing, a shaft, a bearing, a bearing plate, and a seal. The housing includes first and second housing components directly engaging one another along a housing interface. The housing at least in part defines a sealed chamber. The shaft is at least in part received in the chamber. The bearing rotatably supports the shaft. The bearing plate defines a bearing housing at least substantially receiving the bearing. The housing circumscribes the bearing plate such that the bearing plate is enclosed within the housing. The bearing plate is fixed to a supporting one of the housing components and directly engages the supporting one of the housing components along a bearing plate interface. The seal is disposed along at least one of the interfaces.

A dual-chambered beverage container in the form of a shot glass. The interior of the glass is bisected via a hinged divider flap, creating two separate chambers within the glass. The upper chamber holds a first beverage, preferably a shot of hard liquor, while the bottom chamber holds a volume of a second beverage, such as soda or juice. When the shot glass is in a resting position, the divider flap is closed, segregating the beverages in their respective chambers. A user begins to drink the first beverage, the hinged diver flap will slowly swing open, allowing the second beverage to flow out of the bottom chamber, through the upper chamber, and into the user's mouth. Thus the user experiences the taste of the shot of hard liquor only briefly before consuming the chaser beverage.

An example end cap of a stator segment is provided for use in locating wires in a segmented stator assembly in desired positions. The end cap generally includes a body and an inboard wall. An identifier is defined by the inboard wall of the end cap for use in determining wire sizes to be used with the end cap. Terminal pockets are provided in the body for receiving the wires and making desired electrical connections, and steps located in the terminal pockets help secure the connectors in the terminal pockets. Plateaus, and troughs defined in the plateaus, are located outside the terminal pockets for use in trimming wires received in the terminal pockets as desired. And, retaining structures are located around the end cap to help with locating the wires in the desired positions.
