Gridlock current is the current measured while keeping the rotor at rest, and the motor gridlock is a situation in which the motor still outputs torque when the speed is zero, which is generally mechanical or artificial. The following is with Senli motor Xiaobian to look at, relatedThree-phase asynchronous motorThe locked-rotor current.

       When the motor load is too large, the dragged mechanical failure, bearing damage, motor cleaning failure, may cause the motor can not be rotated. When the motor is blocked, its power factor is very low, the blocking current is large, and the time is slightly longer, which is likely to cause the motor winding to burn out. But just to testThree-phase asynchronous motorIn some performance, it is necessary to carry out locked-rotor test on the motor, which is carried out in the type test and inspection test of the motor.

       The lock-rotor test is mainly to measure the lock-rotor current, lock-rotor torque value and lock-rotor loss when the rated voltage is measured. Through the analysis of the lock-rotor current size and the three-phase balance, the reasonability and some quality problems of the magnetic circuit composed of the motor and rotor are reflected.
