A winding assembly for an electric generator includes a stator core having a relatively cylindrical inner shape. Also included is a rotor core coaxially rotatable within the stator core, wherein the rotor core includes an input shaft. Further included is a rotor winding support structure on the rotor core and comprising a surface disposed at an angle relative to the input shaft and extending radially outward from the input shaft toward the stator core. Yet further included is a rotor winding bundle disposed along, and supported by, the surface of the rotor winding support structure.

Winding assembly for an electric generator and motor rotor and method of maintaining position of a winding assembly

An electric motor includes a stator assembly having an annular stator core with an inner diameter and an outer diameter. The inner diameter is formed with a plurality of winding slots extending from a first end of the stator core to a second end of the stator core. A plurality of windings are disposed within the winding slots beginning with a first slots. The windings are coupled into at least one winding group associated with at least a first phase, and each winding has a first winding end and a second winding end extending from the first end and the second end, respectively, of the stator core. At least one thermal fuse is disposed in thermal contact with the first winding end and substantially adjacent to the first winding portion.

Electric motor and a method for making an electric motor

Plastic deformation and nicking of the conductors (30) of the end turns (20) in the stator (10,12,14) of a dynamoelectric machine during the installation of a temperature sensor (26) is avoided by locating the temperature sensor (26) in a gap (22) between the coils defining adjacent end turns (20), thereby providing a machine capable of rapidly responding to excess heat even in a locked rotor situation before detectable levels of smoke, gas, and odors are generated.

Method of installing thermal protection for an electric motor stator

Long thermal paths and the resulting slow response times in sealed and electrically insulated thermal sensors may be substantially reduced by insulating and sealing the sensor (26) by a method which includes the steps of providing (30) an electrostatic fluidized bed of electrically insulating resin; locating (34) the sensor (26) at the bed; coating (36) the sensor (26); removing (38) the sensor from proximity to the bed; and curing (40) to the resin to form a uniform, thin coating encapsulating the sensor (26).
