<P>PROBLEM TO BE SOLVED: To provide a synchronous motor with low vibration and an electric driving device. <P>SOLUTION: The synchronous motor of a field winding type is provided with a stator 102 having a stator winding where supply power is controlled so that driving torque becomes small as the number of rotations of a rotor becomes high, a stator 102 formed of the rotor having field winding controlled in such a way that field current becomes small as the number of rotations of the rotor becomes high, and the rotor 110 supported to an inner peripheral side of the stator 102 so that it can rotate. The rotor 110 is formed of a pawl magnetic pole rotor of a tandem structure where a plurality of pairs of pawl magnetic poles of N pole and S pole, which are excited by field winding, are connected in an axial direction. A plurality of pairs of pawl magnetic poles of the pawl magnetic pole rotor with the tandem structure are shifted in a circumferential direction. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
