Abstract
According to the invention, an insulator is provided at the axial ends of a rotor core. The insulator has radially spaced rows of notches at intervals approximately equal to the diameter of the winding wire for guiding placement of the turns of the winding at a predetermined location. After completion of the first turn, the wire is skewed at a first angle with respect to the plane of the first turn to coincide with the second notch and the remainder of turns in the first layer in turn completed in substantially parallel relationship. At the completion of the last turn of the first layer, the wire is crossed over the next to the last turn, skewing the winding in an opposite direction and situating the wire in the valleys formed between the successive turns in the first layer. The sequence continues alternately for the remaining layers.
