The paper introduces a numerical procedure of an asynchronous motor optimum frequency and feed sine-wave voltage selection for given values of the motor speed and load moment to provide minimum power loss. Key words – asynchronous motor, stationary loading mode, mathematical description, optimum voltage, optimum frequency, power loss. ISSN 2074-272X. . 2013. 3  (...truncated)
