Abstract
Abstract An electric motor is adapted to be coupled directly to apparatus for performing work, such as a pump, for example, which has a casing and a shaft projecting therefrom. The rotor of the motor, which is adapted to be positioned adjacent to the shaft in axial alignment therewith, is journaled at its end removed from an end wall of the casing. A flexible disk is fixed to the opposite end of the rotor which is not journaled. Instead, a hollow hub which is carried by the disk at its axis of rotation and receives the shaft provides an arrangement for directly coupling the motor to the shaft.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
130 words
For use with apparatus for performing work having a casing and a shaft projecting from an end wall thereof, a. an electric motor including a rotor adapted to be positioned adjacent to the shaft in axial alignment therewith, b. means for journaling the end of said rotor removed from the end wall of the casing, the opposite end of said rotor nearer to the end wall of said casing being characterized by the absence of journaling means, c. means for coupling said motor directly to the shaft, d. said coupling means comprising a flexible disk fixed to the end of said rotor nearer to the end wall of the casing, and e. a hollow hub which is carried by said disk at its axis of rotation and receives the shaft.
Claim 2
Dependent Claim
130 words
For use with apparatus for performing work having a casing and a shaft projecting from an end wall thereof, a. an electric motor including a rotor adapted to be positioned adjacent to the shaft in axial alignment therewith, b. means for journaling the end of said rotor removed from the end wall of the casing, the opposite end of said rotor nearer to the end wall of said casing being characterized by the absence of journaling means, c. means for coupling said motor directly to the shaft, d. said coupling means comprising a flexible disk fixed to the end of said rotor nearer to the end wall of the casing, and e. a hollow hub which is carried by said disk at its axis of rotation and receives the shaft.
Claim 3
Dependent Claim
45 words
An electric motor as set forth in claim 1 in which said rotor comprises a winding short-circuited at its opposite ends by short-circuiting rings, said flexible disk at its peripheral edge portion being fixed to said ring nearer to the end wall of the casing.
Claim 4
Dependent Claim
42 words
An electric motor as set forth in claim 1 in which said hollow hub at the opening therein has an axially extending groove, and means for detachably locking said hub to the shaft comprising key means disposed in the axially extending groove.
Claim 5
Dependent Claim
47 words
For use with apparatus as set forth in claim 1 in which the shaft thereof is provided with resilient key means, said hollow hub at the opening therein having an axially extending groove to receive said resilient key means for detachably locking said hub to the shaft.
