<P>PROBLEM TO BE SOLVED: To stably drive a multipolar motor used in a large electric automobile, a hybrid automobile or the like by a system constituted at low cost. <P>SOLUTION: In a three-phase eight-pole alternating current motor, coils of phases U, V, and W of eight poles of a stator are divided into four coil groups of a first coil group C1, a second coil group C2, a third coil group C3, and a fourth coil group C4 by two poles. U, V, and W power lines are made independent with respect to each coil group C1, C2, C3 and C4, and connected to four inverters of a first inverter I1, a second inverter I2, a third inverter I3, and a fourth inverter I4. These inverters I1 to I4 are operated by one control computer S in synchronization. <P>COPYRIGHT: (C)2008,JPO&INPIT |
