Abstract
An electrical machine can include a rotor core rotatably coupled to a shaft, and having a set of rotor windings including a termination end extending axially out the core and electrically connected to a terminal. A lead restraint assembly is arranged to rotatably restrain the termination end in a channel.
Claims20
An electrical machine comprising:
- a drive shaft rotatable about an axis of rotation;
- a rotor assembly rotatably coupled to and circumscribing the drive shaft, the rotor assembly including a rotor core defining a set of axially-extending slots, and a set of rotor windings disposed in the axially-extending slots, the set of rotor windings including a portion extending axially out of a slot defining a termination end, and electrically connected to a terminal;
- a first lead restraint, rotatably coupled to the drive shaft, and disposed radially inward from the termination end, the first lead restraint defining a radially-extending channel therein, wherein a portion of the termination end is disposed in the radially-extending channel;
- and
- a second lead restraint, rotatably coupled to the drive shaft, and disposed at an axial end of the first lead restraint, the second lead restraint arranged to cover at least a portion of the radially-extending channel.
2 more elements
A method of assembling a lead retention assembly onto a rotor assembly having a drive shaft and a rotor core coupled with the drive shaft, the method comprising:
- arranging a first lead restraint against the rotor core of the rotor assembly such that a termination end of a winding is received within a radially-extending channel defined by the first lead restraint;
- and
- arranging a second lead restraint relative to the first lead restraint such that the second lead restraint covers at least a portion of the termination end and the first lead restraint, and receives the termination end within a first recess defined by the second lead restraint.
