<p>PROBLEM TO BE SOLVED: To provide a driving equipment which is much more reduced in size and weight. SOLUTION: This equipment is provided with a stator 1410 having windings, a first rotor 1210 having windings and connected to an engine output shaft, and a hollow cylindrical second rotor 1310 located in the middle between the first rotor 1210 and the stator 1410 and connected to driving wheels. An inner magnetic circuit is formed between the first rotor 1210 and the second rotor 1310, and an outer magnetic circuit is formed between the second rotor 1310 and the stator 1410, thereby giving and taking torque among the first rotor 1210, the second rotor 1310, and the stator 1410. Rotor windings 1211 of the first rotor 1210 are concentratedly wound in a yoke section 1212c of a rotor core 1212 and therefore the size and weight of the first rotor 1210 can be reduced. The diameter of the first rotor 1210 is small and therefore those of the second rotor 1310 and stator 1410 are also small, and the size and weight of the entire equipment can be made extremely small.</p> |
