Nettet30. okt. 2008 · Skrevet 1. november 2008 (endret) En frekvensoimformer kjører som sagt opp frekvensen på 100Hz mens spenningen blir for høy ettersom omformeren kompenserer etter en motor laget for 50Hz. Når dere kjører den på 50Hz blir induktansen i motoren mye mindre og den tottale impedansen for lav og motoren drar mere strøm.
NettetAs the motor starts, the PTC thermistor heats up and at one point switches to a high resistance state.
