Nettet28. okt. 2024 · First, to reduce excessive voltages at the motor terminals, look at cable length, specifications, and installation methods. If the cables are in excess of 50m per phase (from drive output terminals to motor terminals), it is likely that using a drive output filter would be of help. There are a handful of different filter types available, but ... NettetHow to Tell if Your Motor Has Been Overloaded. Your electric motor may run under an overload situation for a while, days or even weeks. In fact, many motors have a rating called Service Factor that allows for periodic short bursts of overloads, just not prolonged overload. A motor run overloaded for a prolonged period will eventually fail.
