Dynamoelektrische Maschine und Verfahren zu ihrer Herstellung

摘要

A dynamo electric machine has a stator core 22 constructed of 90{ symmetrical laminations 26, the windings having differing numbers of poles which overlap in the stator slots. The winding leads 80 are directly connected by insulating cutting terminals to a terminal assembly 56 which is retained in a cut-out in the end frames 50, 52. Holes 62 and projections 60 locate the end frames and the stator assembly, keys 64 holding the assembly together and end frame 52 carries an earthing assembly 218 which engages with the terminal assembly. The rotor comprises three lamination sets 250 - 254, slots 242 of adjacent sets being oppositely skewed. The axis of needle bearing 46 is inclined to the rotor shaft axis such that deformation of the plastics housing part 130 biases the shaft against the bearings to reduce noise.
