摘要： PURPOSE:To enhance the rotary power by suppressing the heating sufficiently thereby suppressing the thermal demagnetization through a simple structure. CONSTITUTION:A connecting line 31 has one end connected with an end bracket 12 by means of a bolt and the other end connected with the engine side lay means of a screw 30 and thereby the end bracket 2 is connected with the engine side through the connecting line 31. The connecting line 31 is made of such material as copper or aluminium having higher conductivity than the yoke member made of iron. Upon turn ON of a starter switch, a current flows from the positive terminal of a battery through a contact 23 at a magnet switch section 2 into a path of a lead wire 21 on the positive pole side a armature winding 10 a commutator 11 a brush 16 on the negative pole side a brush lead wire on the negative pole side an end bracket 12 the connecting line 31 a gear case 25 a fixed part on the engine side a terminal on the negative pole side of battery. The current scarcely flows into the yoke 14 or the permanent magnet 15. This structure suppresses heating due to resistance loss of the yoke 14.

摘要： PURPOSE:To improve the utility rate of a magnetomotive force by forming a stator winding of the first and second windings having different number of poles, and disposing a rotor winding having one or more turns equally on the entire periphery in the number of average of the number of poles of the stator windings. CONSTITUTION:An induction rotary electric machine 40 is composed of a stator having a stator core 11 held in a housing 9 and a rotor having a rotor shaft 4 and a rotor core 5. The winding 10 of the stator is formed of two types of 3-phase windings 10a, 10b having different number of poles, the winding 20 of a rotor is formed of a plurality of rotor winding groups 30, and the number of the groups 3 has the number of average of the first and second stator winding poles. Further, the first winding 10a is connected with a 3-phase AC system 12, and the second winding 10b is connected through a transformer 16 and a breaker 17 with a frequency converter 13. Thus, the rotating speed can be altered by controlling the frequency of the voltage applied to the winding 10b.
