Merry Christmas to all. I have a Fugi VFD (110kw) supplying a motor situated adjacent to the drive. When the drive starts the motor sounds like a cat being strangled (well I assume that is the sound) and while the drive is running radio reception within 100 metres deteriates (static noises). This squealing noise is common to 7 of these drive/motor combos but the static interference is more pronounced with only one unit. The interference is with both mains powered radios and a car radio. I have tried different carrier and noise frequencies with the drives but neither improve the radio reception. The cabling froms the drive to the motor is not screened but the length is less than 1 meter and it is encosed in a metal duct.
Any ideas of extra filters etc that will negate the interference.
