GGOSS Posted November 29, 2005 Report Share Posted November 29, 2005 Hello lalmehal, The short answer to your question is no. There are losses associated with drives of approximately 4%. If the motor is running at full speed and full load via a variable speed drive, the power drawn from the supply will be higher than that of any other form of starter. lalmehal, in future could you please post your questions in the relevant forum ie that would be the "Variable Speed Drives" forum in this case. That fact that you have posted the "Motor Starting" forum could result in VSD experts not seeing your question and therefore not answering it. By posting your question in the correct forum you stand a far better chance of having your question answered quickly and professionally.
