STATOR OF HALF PITCH-TYPE CAPACITOR MOTOR

PROBLEM TO BE SOLVED: To reduce a potential difference between main winding and auxiliary winding, which are brought into contact with each other, and to improve winding insulation performance in a stator of a half pitch-type capacitor motor. SOLUTION: Auxiliary winding wound to a stator core 2 is divided into two windings: first auxiliary winding 7 and second auxiliary winding 8. Second auxiliary winding 8 is wound on the first auxiliary winding 7. One end of an operation capacitor 11 is connected to the beginning 7s of a first auxiliary winding, and the other end is connected to the main beginning 5s or the main end 5e. Thus, the second auxiliary winding in contact with main winding 5 has the largest potential difference, and it can be lower than the potential difference between the main winding 5 and first auxiliary winding.
