PROBLEM TO BE SOLVED: To provide a 12-pole 15-coil motor constitution for three-phase brushless motor which can make the motor constant of a three-phase motor larger without increasing the size of the motor. SOLUTION: In a discoid rotor provided with 12-pole permanent magnets and a three-phase brushless motor having 15 coils, stator coils are successively arranged on a circumference at regular intervals and the coils are groupsed into three groups U-, V-, and W-phased by separately connecting #1, #2, #3, #7, and #12 coils #4, #8, #9, #13, and #14 coils, and #5, #6, #10, #11, and #15 coils in series. In addition, the winding direction of the #1, #3, #4, #5, #9, #10, #14, and #15 coils are made opposite to those of the other coils. |
