Three-phase asynchronous motor The prerequisite for rotation is a rotating magnetic field, and the stator winding is used to generate the rotating magnetic field. The stators are usually separated by three Spaces120°When the stator winding passes through the three-phase power supply, it creates a rotating magnetic field, which isThree-phase asynchronous motorThe basic working principle. So what should we pay attention to during operation? Under what circumstances should an immediate shutdown be performed? It followsMori machineXiaobian to understand together:

       1. During the operation of the motor, the surface should be kept clean, and the air inlet should not be hindered by dust fibers.

       2. The power frequency is different from the rated frequency≤l％; The power supply voltage is different from the rated voltage≤5％
       3. motorThe current must not exceed the rated current10％.
       4. Continuous operation of the motor does not allow long-term overload operation.
       5. There should be no intermittent or abnormal sound or vibration when running without load or load.
       6. when Three-phase asynchronous motorWhen the thermal protection device and short circuit protection device operate continuously, the fault cause should be checked(Whether it's from the motor or from overload or because the protection is set too low)After the fault is removed, it can be put into operation.
       During operation, the temperature rise of the housing is measured with a thermometer, which generally does not exceed75℃. Good lubrication should be ensured during the operation of the motor bearing, and the general motor operation2000HAround, that is, the lubrication finger should be supplemented or replaced(Closed bearings do not need to be greased during their service life). If the bearing is found to be overheating(General bearing temperature rise should not exceed95℃)Or the grease deteriorates, the grease should be replaced in time, the old grease should be removed first, and then the grease of the bearing and bearing cover should be washed with gasolineZIone3Lithium base grease filling the cavity between the inner and outer ring of the bearingl／2(2very)or2／3(4,6,8very).

       When the bearing clearance reaches the following limit wear clearance value, the bearing should be replaced in time. (unit)mm)

       when Three-phase asynchronous motorWhen the following conditions are found during operation, the machine should be shut down immediately
       (1)An electric shock occurred.
       (2)Smoke and fire on the motor or starting device.
       (3)The motor vibrates violently.
       (4)The bearing heats violently.
       (5)The shaft of the motor changes, the bore is swept, the speed drops suddenly, and the temperature rises rapidly.
