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.

A motor unit particularly adapted for connection to a sump pump casing having an upstanding mounting pedestal comprising a fractional horsepower motor having a cylindrical main frame having an upper open end and a lower open end and closed at the lower open end by a first end member and at the upper open end by a second end member and including a motor shaft extending from said first end member, a pump mount adaptor assembly including a bottom adaptor, said bottom adaptor being a plate-like member adapted to be releasably secured to said motor in overlying and immediately adjacent relationship to said first end member and having an outer edge potion substantially aligned with said main frame, attachment means connected to the bottom adaptor adjacent the outer edge of said first end member and coupled to the end of the main frame abutting said first end member, said plate-like member having a central tubular hub in concentricity with said motor shaft, said tubular hub having an end connection means for releasably interconnection to said pedestal for mounting of the moor in vertical orientation and in vertical spaced relation to said pump, and a top adaptor releasably secured to said second end member of said motor and including a continuous overlying member to form a shield over the uppermost end of said motor, said bottom adaptor and said top adaptor being spaced from each other and exposing a substantial length of said main frame.
