PURPOSE:To improve the output of the device by reducing the air gap without increasing the sliding resistance by charging the substance having self lubricity at least into the air gap formed between a stator core and a rotary field pole. CONSTITUTION:When a field coil 7 conducts, a plurality of pole cores 4 and 5 which constitute a rotary field pole are excited, and S and N poles are formed alternately. When a stator coil 9 is conducted, each torque is generated on the pole cores 4 and 5, and a crankshaft 1 is revolved through a flywheel 3. In this device, the substance 17 having self lubricity such as Teflon is charged into the air gap 14 between the pole cores 4 and 5 and the stator core 9. While, the similar respective substances 18, 19 are charged into the air gap 15 between one pole core 15 and the field core 10 or into the air gap 16 between the field core 10 and the flywheel 3. |
