Abstract
A submersible-rated motor with a non-drive end bearing housing that is incorporated directly into the motor housing in a single casting, a terminal plate assembly that includes a terminal box cast directly onto the non-drive end of the motor housing, a drive end seal housing that is configured to enclose an oil reservoir and a shaft seal assembly, and a drive end bearing housing that is mounted completely inside of the seal housing. The seal housing is sealed separately from the motor housing. Both the drive end bearing housing and the seal housing are piloted for concentricity with the drive end of the motor housing.
Claims10
A submersible-rated motor comprising:
- (a) a motor housing that is configured to enclose a stator and a rotor and to partially enclose a drive shaft, the motor housing comprising a drive end and a non-drive end, wherein the motor housing comprises a non-drive end bearing housing that is cast together with the motor housing as a single part so that there is no seal between the motor housing and the non-drive end bearing housing;
- (b) a terminal plate assembly comprising a terminal box and a removable terminal cover, wherein the terminal box is cast together with the non-drive end of the motor housing as a single part so that there is no seal between the terminal box and the non-drive end of the motor housing, wherein the terminal plate assembly is configured to receive one or more stranded power conductors on a first side of a nonconductive terminal plate, wherein each of the power conductors is attached to the terminal plate assembly with a standard compression terminal lug, wherein each terminal lug is bolted to a terminal pin that is both solid and conductive, wherein each terminal pin is fixed and sealed to the terminal plate, wherein each terminal pin comprises a central groove that is configured to receive an O-ring, and wherein the terminal plate assembly is sealed to the motor housing;
- (c) a seal housing that is sealed separately from the motor housing and configured to contain a shaft seal assembly and an oil reservoir, wherein the seal housing is piloted for concentricity with the drive end of the motor housing and sealed directly to the drive end of the motor housing with an O-ring;
- and
- (d) a drive end bearing housing that is mounted completely inside of the seal housing and piloted for concentricity with the motor housing, wherein the drive end bearing housing is configured to enclose a first ball bearing situated around the drive shaft on the drive end of the motor;
- wherein the non-drive end bearing housing is configured to enclose a second ball bearing that is situated around the drive shaft on the non-drive end of the motor.
