Estimation of currents and temperatures in asynchronous motors up to 400 kw at various asymmetry in its supply network: methodical approaches
The technique of electromechanical and thermal characteristics estimation in AC motors is offered at asymmetry of network voltage at the most adverse phase values shift for direct and reverse sequence of phase voltages. Its using at designing of electric motors allows excluding the overheating of windings connected to change of phase shift at operation of the motor.
