<p>An electrotechnical regulating device for asynchronous rotating machines comprises capacitors in series with the windings of the asynchronous motor. In order to regulate the speed of rotation of an asynchronous motor, the device further comprises a variable-impedance short-circuiter connected in parallel between at least one of the windings and the associated capacitor or capacitors. The device serves to modify the torque of an asynchronous motor supplied at a variable frequency and at a fixed voltage, in order to control the speed of an asynchronous motor which is supplied at fixed or variable frequency or in order to regulate the voltage of an induction generator which rotates at a fixed or variable speed.</p> |
