摘要
The thermal capacity of totally enclosed fan-cooled converter-fed induction motors varies at the different operating frequencies. Main effects are due to the variation of the cooling airflow, the variation of iron losses, and eventually, the presence of harmonies. This paper presents the results of a complete evaluation of these effects and of the thermal torque at the different operating speeds.
