PROBLEM TO BE SOLVED: To provide an AC commutator motor capable of reducing pulsation torque and armature reaction simultaneously. SOLUTION: A two-pole AC commutator motor includes: a stator 7 including a stator core 5 having a yoke 51 and a magnetic pole 52 and a field winding 6 wound to the magnetic pole 52; and a rotor 15 including an armature core 11, an armature winding 14 provided in a slot formed in the armature core 11, and a commutator 12 to which the armature winding 14 is connected, and delivers power to the armature winding 14 via the commutator 12 and a brush 16. A step difference is provided to the end of the surface which does not face a rotor of a magnetic pole piece of the magnetic pole 52. COPYRIGHT: (C)2011,JPO&INPIT |
