Mechanical characteristics of an asynchronous motor with a pulse controller in the rotor circuit.

Abstract

The method of calculating the mechanical characteristics of the motor with a thyristor switch, a smoothing choke and a protective circuit of a resistor and a capacitor in the circuit of the rectified rotor current is described. In deriving the calculated ratios, the parameters of the switch elements are taken into account. The method allows calculating the mechanical characteristics in the zone of continuous rectified rotor current depending on the duty cycle, switching frequency and parameters of circuit elements. Experimental and calculated mechanical characteristics are given. Ill. 3, Bible. 3.
