Induction machine and method for manufacturing a rotor of the induction machine.

摘要

For controlling an induction machine accurately by an inverter controller or a vector controller, electric resistance of secondary-conductors (14) of a rotor (10) of the induction motor is kept in a predetermined range by cooling the secondary-conductors (14) directly by air flow. For generating the air flow, vanes (21) are provided on both ends of the rotor (10) against the rotation axis (11) of the rotor (10). A ventilation path (15) is formed in and along each secondary-conductor (14) in which the air flows.
