Analysis of 6 reasons for the smoke phenomenon of the three-phase asynchronous motor, Dalan Motor reminds you to pay attention!
Generally, the smoke phenomenon of three-phase asynchronous motors is considered to be high temperature, which causes the motor to overheat and produce smoke, but the cause of smoke is more than this. The smoke phenomenon of the motor can be found out of 6 reasons. Now Dalan Motor is small The editor makes the following introduction for everyone:
(1) The voltage of the motor is too low or overload: the dragged machine is stuck or poorly lubricated. This problem may be caused by the voltage is too low or the power cord is too thin. Replacing the power cord can increase the voltage. If an overload occurs The load should be reduced.
(2) Poorly ventilated motor or sun exposure: first check whether the motor fan is damaged or not fixed tightly, pay attention to whether there are objects that affect the ventilation, and remove it in time to avoid temperature rise.
(3) The motor voltage is too high or the wiring is wrong: If the motor voltage is found to be too high, it will produce smoke. At this time, the voltage should be appropriately reduced, and then check the wiring for problems. If it is found, the circuit should be corrected immediately.
(4) Frequent forward and reverse rotation of the motor or excessive starting times: appropriately reduce the forward or reverse running or starting times of the motor, or use other types of motors to reduce generator damage.
(5) Motor stator and rotor phase friction: If the bearing is loose, new bearings must be replaced; file the stator and rotor phase friction parts to correct the centerline of the rotating shaft.
(6) The stator winding of the motor is short-circuited or the stator winding is partially grounded: when the motor is turned on, you can smell it or observe whether there is a scorched coil or part. You can also touch the winding by hand, compare the temperature, find the short circuit, and carry out Handle separately.
