In a certain range, it can automatically adjust the relationship between the load torque (torque) and the speed; This is the biggest feature of the three-phase asynchronous motor. Below and Senli motor Xiaobian together to understand the next.

       In the maximum torque range of the motor, the torque will increase with the decrease in speed, the motor load increases, the speed will inevitably decline, but the rotating magnetic field cutting conductor speed increases, induction of a larger current in the rotor conductor, increasing the electromagnetic force on the rotor's driving effect, so that the motor produces a larger torque.

       In the case of three-phase asynchronous motor overload, the rotor speed will decrease, so in the case of constant frequency of the power supply, the stator cutting rotor guide bar speed becomes larger, it will produce a greater induced electromotive force in the rotor, and the resistance of the rotor guide bar is certain, so the rotor guide bar generated by the current will be larger than normal operation.

       According to the left hand rule, the magnetic field force and current are directly proportional, so that the electromagnetic power output on the rotor will increase, and then the mechanical power output on the rotor will increase, so that the three-phase asynchronous motor has been running near the stable point. The rated torque is the torque that the motor can run stably for a long time.
