Dear Sir, Lady, I have an LG WD-10655TP washing machine. When I try to run this from a Sincro 4 pole 4.4 Kw alternator running at 1500 RPM AC cycles 50Hz exactly, the drum in the washing machine runs jerky, and the motor makes a noise it does not do when running from the electricity supplier. Please let me know if you have advice. Thanks. Hannes. South Africa.
