working principle of triple-pg娱乐电子游戏

the magnetic field generated by the three-phase motor winding on the three-phase power supply rotates in space, which is called the rotating magnetic field. the speed is determined by the number of poles of the motor and the frequency of the power supply.

the rotor moves relative to the stator in the magnetic field, cutting the magnetic poplar to form the induced electromotive force.

the rotor copper strip is short-circuited and induced current is generated.the rotor copper strip has an electric current and is subjected to a force in the magnetic field.the rotor will rotate.

one: have a rotating magnetic field,

second: the rotation direction of the rotor is the same as that of the rotating magnetic field.

third: the rotor speed must be less than the synchronous speed, otherwise the conductor will not cut the magnetic field, no induced current generation, no torque, the motor will stop, stop, speed slowed down, because there is a speed difference, the rotor began to rotate, so as long as the rotating magnetic field exists, the rotor is always behind the synchronous speed in rotation
