It is possible that there is a mechanical overload on the motor that may cause repeated tripping and even damage to the electric motor winding. in this case, it is important to reduce the load as quickly as possible as buying a new motor can be an expensive proposition and will add to the operational costs.
Apr 01, 2003nbsp018332for example, if a 100 hp motor has an unbalance factor of 3 percent, the motor should be derated to 0.88 or 88 percent of capacity, 88 hp. the frequent use of variable frequency drives vfds can result in detrimental effects to electric motors because
Electric motors have a rated voltage and frequency and a rated full load current which can all be found on the motor nameplate. motors must be operated at rated voltage and frequency, and the motor overload can then be calculated by comparing the actual motor current to the rated full load current.
