Starting Current

Starting Current

 

the current drawn from the mains by an electric motor upon starting. Since the starting current of an electric motor can be several times greater than the motor’s rated current, it becomes necessary to limit the current by means of a starting resistance. It is sometimes also necessary to limit the starting current in order to reduce the starting torque to a value dictated by the mechanical strength of the shafts and other parts of the driven mechanism or to achieve the smooth start required by certain production processes. The goal is usually to obtain the required torque with the minimum starting current.
