General analysis of the three-phase asynchronous motor with spiral sheet rotor: operation, parameters and characteristic values
Rights accessOpen Access
The objectives of this article arise through the investigation of a motor with a high starting torque although with limited intensities, weak intensity variations depending on the load, controlled losses in no-load tests, and an acceptable performance in steady state and with a good response in transient periods. All these requirements would have to be obtained without the help of power electronics, in this way the motor would be more robust, longer lasting and without the need for auxiliary equipment. In this article, the operation principle, the characteristic parameters and the obtained results for the spiral sheet motor are analyzed for three speed regimes 1000, 1500 and 3000 rpm. Also, at the end of the paper the spiral sheet motor is compared with the squirrel cage rotor, the solid rotor with rings, the wound rotor with additional resistances in the rotor circuit, and the hollow diamagnetic rotor.
