Abstract
Abstract In an electric motor with a rotor and shaft fixed for rotation in unison and a U-shaped bracket connected to each side of the stator, the bight portion of each bracket having a deformation and opening therethrough substantially aligned axially with the deformation and opening of the other bracket and the rotor bore of the stator. Bearing arrangement for the shaft on both sides of the rotor each having an end portion of similar shape and engaging one of the deformations and being connected thereto by an epoxy so the bearing arrangement retains the rotor in alignment with the rotor bore.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
144 words
In an electric motor having a through bore, and a rotor axially aligned in said bore and having a through shaft connected to and rotatable with said rotor, the combination comprising: a pair of bracket means each connected to a different side of the stator, each of said bracket means having a seat surface and an opening for said shaft therethrough substantially aligned axially with said bore of said stator and said seat surface and opening therethrough of the other of said bracket means, bearing means for said shaft disposed on each side of said rotor each having an end portion engaging the seat surface of one of said bracket means and being similar in shape to the seat surface said end portion engages, and epoxy connecting said end portions to said bracket means for immovably locking said bearing means to said bracket means.
Claim 2
Dependent Claim
144 words
In an electric motor having a through bore, and a rotor axially aligned in said bore and having a through shaft connected to and rotatable with said rotor, the combination comprising: a pair of bracket means each connected to a different side of the stator, each of said bracket means having a seat surface and an opening for said shaft therethrough substantially aligned axially with said bore of said stator and said seat surface and opening therethrough of the other of said bracket means, bearing means for said shaft disposed on each side of said rotor each having an end portion engaging the seat surface of one of said bracket means and being similar in shape to the seat surface said end portion engages, and epoxy connecting said end portions to said bracket means for immovably locking said bearing means to said bracket means.
Claim 3
Dependent Claim
39 words
The electric motor in accordance with claim 1, and a pair of reservoirs each connected to one of said bracket means and enclosing the end of said bearing means opposite from the end connected to the same bracket means.
Claim 4
Dependent Claim
52 words
The electric motor in accordance with claim 1, wherein each of said bracket means is a U-shaped bracket having a pair of leg portions connected to said stator and a bight portion spaced from said stator by said leg portions, and said bight portion having a spherical deformation providing said seat surface.
Claim 5
Dependent Claim
37 words
The electric motor in accordance with claim 1, and each of said bearing means comprising: a bushing, and flange means at one end of said bushing providing said bearing means end portion connected to said seat surface.
Claim 6
Dependent Claim
22 words
The electric motor in accordance with claim 4, wherein said flange means is a disc connected to the end of said bushing.
Claim 7
Dependent Claim
57 words
The electric motor in accordance with claim 5, wherein said disc is substantially spherical, each of said bracket means is a U-shaped bracket having a pair of leg portions connected to said stator and a bight portion spaced from said stator by said leg portions, and said bight portion having a spherical deformation providing said seat surface.
Claim 8
Dependent Claim
39 words
The electric motor in accordance with claim 6, and a pair or reservoirs each connected to one of said bracket means and enclosing the end of said bearing means opposite from the end connected to the same bracket means.
