Shengzhou Senli Motor focus on plastic machineryTorque motorToday, the Senli Motor Xiaobian will take you to understand how some specific reactions of the motor after the lack of phase are.
Previously, Senli Xiaobian also wrote a similar three-phase asynchronous motor lack of phase can start the problem, today to understand the reaction of the lack of phase, you can carefully observe the three-phase asynchronous motor in the hand,Three-phase torque motorFor such products, if all the windings of one or two phases of the three-phase motor are burned out, it is generally caused by the lack of phase operation; The main phenomena are: regular overheating of the winding produces burning black, but the normal phase adjacent to the fault is lossless; The motor after the lack of phase can generally continue to run, but the single-phase running speed caused by the lack of phase will have a significant decline.
After phase missing, three-phase asynchronous motor,Three-phase torque motorSuch products can continue to run in the direction, but the speed decreases significantly, and the rate of magnetic field cutting conductors increases, which is easy to burn the motor due to overheating.
Motor missing phase yesTorque motor manufacturersImportant monitoring items in the factory test, in peacetime for its daily maintenance or overhaul is also to carry out phase inspection, check the reliability of load switches, power lines, static and dynamic contacts, eliminate phase operation, and through the reliable action of the overcurrent protection system to prevent burning motor windings.
