High rotating speed, high power electrical motor.

摘要

The present invention relates to a high-power electric motor with high rotational speed consisting of a stator and of a rotor, the rotor comprising a shaft (4) on which is mounted, by clamping with the aid of two plates (3) which are integral with the shaft (4), a magnetic mass (1) consisting preferably of a stack of rotor laminations and a squirrel cage consisting of a plurality of longitudinal bars (3) linked together by the plates (2) performing the function of short-circuit rings, the motor being characterised - in that the bars (3) of the squirrel cage are fixed to the rotor at a single point, and - in that the ends of the bars (3) are freely arranged in suitable orifices or bores formed at the periphery of the said short-circuit rings (2) or plates. <IMAGE>
