PURPOSE:To increase the coefficient of utilization of the coil as well as to contrive miniaturization and lightweightedness of the titled motor by a method wherein the connection of the coil is performed in such a manner that no clearance will be made on the coil even when its pole is changed. CONSTITUTION:The number of stator grooves of the motor is set at 16n, and the coil 2n group, in which four main coils L are arranged in distributed winding at a four-slot pitch respectively, is provided in said grooves. The coil ends of the 2n group are connected in series in such a manner that they constitute main coil groups L1 (L11, L12 and L13) and L2(L21, L22 and L23). On the other hand, a coil 4n group, wherein two auxiliary coils l were arranged in distributed winding, is arranged and auxiliary coil groups l1 (l11-l26) and l2 (l21-l26) are constituted by the 4n group. The coil groups L2 and l2 are connected in series to the coil groups L1 and l1 respectively, and also they are switchably connected to make the current in reverse direction, thereby enabling to perform the switching of the 2n pole and the 4n pole. |
