Three-phase asynchronous motorIn no-load operation, the current passing through the three-phase winding of the stator is called no-load current; Most of the no-load current is used to generate rotating magnetic fields, so it is also known as no-load excitation current, which belongs to the reactive component of no-load current.

       Some no-load current is used to generateThree-phase asynchronous motorThe various power losses during no-load operation, such as friction, ventilation and core loss, etc., of course, some no-load current is caused by the work component, because the proportion is relatively small, so it is generally ignored.

       Therefore, we generally think that no-load current is reactive current; In this way, in fact, the smaller it is, the better, so that the power factor of the three-phase asynchronous motor will be improved, and it is good for the power grid; generalSmall three-phase asynchronous motorThe no-load current is about the rated current30%-70%;

       If the motor is no-load, the magnetic field on the stator and rotor will have a certain slip rate, and the slip rate will produce cutting magnetic force lines, and will generate current in the rotor cage bar, or winding, which requires power current to support, which is the main component of no-load current.
