The main ratios when starting an asynchronous electric drive with the introduction of a stator phase by a condenser.

Abstract

Formulas are derived for determining the values of capacitive resistance, in which the negative moment of the engine becomes maximal, and also equal to zero. A number of formulas for determining the current in the capacitor and the voltage drop on it are obtained. A study is made of the torque of the moment on the extremum. Based on the conducted research, recommendations are given on the magnitudes resistance of the rotor chain.
