- 21 - Abstract An adaptor assembly for a motor permits mounting to a pump to form a sump pump unit. A motor main frame has its end by end bearing frames. The adaptor assembly includes top and bottom plate adaptors formed of cast plastic or aluminum, and are separately inventoried for connection to a line of motors built for other applications as well as sump pumps. The bottom adaptor plate is secured to the end frame, with the motor shaft projecting concentrically of a hub extending from the plate. The hub telescopes over a tubular pedestal of the pump and has a collapsing collar for mounting the motor to the pump with the pump shaft and motor shaft coupled by a mating slot and projection. The plate is secured to the motor by suitable edge securement clips or by self tapping screws passing through a plate opening and threaded into a hole in the end frame. A top adaptor unit has a plate similarly secured to the top end of said motor. A tubular skirt extends from the top plate over the motor frame with a flared skirt aligned with cooling openings in the main frame. A relay housing is integrally formed to the exterior side of said top adaptor plate and connects to a releasably covered terminal board opening. A current sensitive relay in the housing is connected in circuit to respond to current in the motor winding in response to a "run" current flow and open contacts in circuit to a start winding of the motor winding. - 21 -
