Abstract

PURPOSE: To miniaturize an armature core by changing the connection of a single winding to obtain a winding with a ratio of number of poles of 1 to 4.
CONSTITUTION: Coil elements U11 and U12, V11 and V12, W11 and W12, U21 and U22, V21 and V22 W21 and W22 form the phase belts respectively, -U11 and -U12 make up a coil with U11 and U12. Conductive directions of U11 and U12 are opposite to each other. The coil elements -V11, -V12, -W11, -W12, -U21, -U22, -V21, -V22, -W21 and -W22 are the same as said case. The coil pitch is selected at 5/6 × 100%. When operated in changing two poles to eight poles, the polarity of coil U12, which is mounted on the same groove 2 as that of the other phase coil of U11 and U12 making up an arbitrary phase belt, is inverted. Next, the polarity of coil -U21 mounted on the groove 7 is inverted. In the same way, the polarity of coils V12, -V21, W12 and -W21 are inverted.
