Abstract: A motor is provided for use in a machine. The motor includes a segmented stator and a resiliently flexible clip. The stator includes a core having spaced apart arms and a yoke. The arms define an opening therebetween, and the yoke spans the opening. The clip is removably retained on the core so as to apply pressure against each arm toward the yoke such that the arms are retained in contact with the yoke.

Abstract: A stator is formed from two stacks of laminations have different outer perimeters to enable electrical motors with different output ratings to be built with a same hub-to-hub distance. The stator includes a first plurality of laminations having a first outer perimeter with at least two flanges with mounting holes, and a second plurality of laminations having a second outer perimeter that is different than the first outer perimeter. The second outer perimeter of the laminations in the second plurality of laminations are configured to enable a portion of an endplate to pass the second plurality of laminations and contact a face of the first plurality of laminations.

Abstract: An electric motor has been developed that includes a housing to prevent particles from exiting one compartment of the motor, while enabling air flow through another compartment of the motor. The enclosed compartment includes a printed circuit board having a plurality of electronics components to prevent debris produced by a catastrophic failure of an electronic component from escaping the housing. Vents are provided in a separate portion of the housing to enable air to circulate about the primary components of the motor.

Abstract: A motor is provided for use in a machine. The motor includes a frame having a catch and a mounting ring retained on the frame by the catch. The motor is supported in the machine by the mounting ring.

Abstract: An electric motor assembly is configured to be mounted within a machine in a selected one of multiple possible motor dispositions corresponding with different motor axis positions. The motor assembly includes an endshield having a pair of opposite generally radially-extending mounting flanges. Each mounting flange presents an engagement portion that includes a plurality of spaced apart, dissimilarly-shaped recesses that extend in a generally common direction. The pair of flanges cooperatively present corresponding sets of like-shaped recesses, each of which is associated with one of the motor dispositions, but only one of the sets of recesses extends entirely through the engagement portions to define a single set of like-shaped fastener-receiving through holes corresponding to the selected motor disposition. A method of manufacturing components for electric motor assemblies configured to be mounted within respective machines in a selected one of multiple possible dispositions is also disclosed.

Abstract: An electric motor comprises a stator, a rotor, and an interface plate. The interface plate is fixed to the stator and is configured to couple the electric motor to a pump. The interface plate comprises a shaft opening, a cavity, a ventilation passageway, a fluid discharge portion, a drainage passageway, and an upwardly extending surface. The rotor shaft extends horizontally through the shaft opening. The cavity is in communication with the shaft opening. The ventilation passageway extends upward from the cavity and is in communication with the cavity and with the ambient air. The drainage passageway is in communication with and extends downward from the cavity. The drainage passageway is configured to channel liquid downward from the cavity and to the fluid discharge portion. The upwardly extending surface is positioned where the upwardly extending surface will inhibit liquid from migrating from the fluid discharge portion to the stator.

Abstract: A motor includes a rotor having at least one magnet. A stator includes multiple teeth and a sensor adjacent the magnet, or adjacent an air gap that is defined between the rotor and the stator. The majority of the teeth are identical in shape, or at least substantially identical. However, there is at least one distinct tooth (from among the teeth) that has a recess shaped to receive the sensor or a sensor housing. Thus, the distinct tooth has a different shape than the majority of the teeth to accommodate the sensor or sensor assembly.
