い安価な軸方向空隙誘導電動機を提供するものである。In this configuration, since the pair of rotors 3a and 3b are constructed of a cage type with an iron core, the moment of inertia of the rotor is large and the starting torque is also relatively small, making it difficult to perform forward/reverse rotation operation or start/stop operation. There were problems such as it being difficult to repeat the operation frequently and the input current becoming large.Objective of the InventionThe present invention solves these conventional problems and provides a rotor for a pair of axial air gap induction motors. By using a squirrel cage rotor with iron core on one side and a squirrel cage rotor with iron core on the other side, the characteristics of both can be utilized, and the starting torque can be increased due to the combination of the two, and the moment of inertia can also be reduced. The present invention provides an inexpensive axial gap induction motor with a small amount of air gap.
