 Asynchronous motor no-load running, the current in the three-phase winding of the stator, is called the no-load single phase motor current. Most of the no-load current is used to produce a rotating magnetic field, known as the no-load excitation current, no-load current reactive component. There is a small part of no-load current ac motor prices is used to produce all kinds of power loss during no-load running (such as friction, ventilation and core loss), the no-load current is a part of the active component, due to account for the proportion of small, negligible. Therefore, can think of is reactive current idle current. From this point of view, it is as small as possible, so that the power factor of the motor raised, the power supply is good.

If no load current is big, because of the stator winding conductors carrying area is certain, allowed through current is certain, allows for active current can reduce flows through a wire, the motor can drive the load will be reduced, the motor output is reduced, with too much load, winding would be easy to fever. But the no-load current also cannot too small, otherwise will affect the other performance of the motor. Generally the no-load current of the small motor Three phase motor is about 30% ~ 70% of rated current, the no-load current of the large and medium-sized motor is about 20% ~ 40% of rated current. What is specific to the no-load current of an electric motor, the motor nameplate or product manuals, generally not marked. Have electrician often need to know how much is this value, this value to judge the quality of the motor repair, can use.
