The motor contains two parts: the stator and the rotor. The stator winding is the electrical circuit of the motor, which is connected to the three-phase alternating current to produce a rotating magnetic field. The rotor obtains a certain torque and rotates under the action of the rotating magnetic field, which drives the mechanical load to work. Therefore, the motor is an inductive load and will generate a large inrush current at the moment of starting (see the figure above).
