Claim 12:
13. A motor and control apparatus therefor, characterized in that the motor and control apparatus comprises:
stator magnetic poles SP71, SP72 and SP73 whose number is “SN7×MN7” pieces, arranged in a circumferential direction of the stator,
a winding SW71 wound to magnetically excite the stator magnetic pole SP71,
a winding SW72 wound to magnetically excite the stator magnetic pole SP72,
a winding SW73 wound to magnetically excite the stator magnetic pole SP73,
a power element PE71 electrically connected in series to the winding SW71,

a power element PE72 electrically connected in series to the winding SW72, and
a power element PE73 electrically connected in series to the winding SW73,
a rotor RTR7 provided with rotor magnetic poles whose number is a RN7 piece which is defined as being “SN7×MN7”-piece or more and “3×SN7×MN7” or less,
wherein
each of the stator magnetic poles has a circumferential angle width θst7 which is smaller than “360°/RN7−720°/(SN7×RN7)”, and
each of the rotor magnetic poles has a circumferential angle width θrt7 which is smaller than “360°/RN7−720°/(SN7×RN7)”,
wherein the numeral SN7 is a positive integer of 6 or more, the angle is an electrical angle, and the numeral MN7 indicates the number of pole pairs and is a positive integer of 1 or more.
