1、合闸后电动机应立即起动起来，达到正常转速并平稳运行，否 则皮立即切断电源，检查并排除故障。

2、起动后注意观察电动机传动装置、负载机械、电压表和电流表， 若有异常现象应立即停机。

3、电动机空载连续起动一般不超过4次，运行至热态停机后连续 起动不得超过2次，否则容易烧坏电动机。

4、根据电网容量、负载大小和电动机功率等，合理选择起动方式， 较大功率电动机宜采采用一三角法或降压方式起动。

运行

1、电源电压与额定电压的偏差不超过±5%，三相电压不平衡不超过1.5%。

2、电动机运行电流不得超过铭牌上的额定电流，三相电流不平衡量不超过80%，否则会造成电动机发热甚至烧毁。

3、用温度计测量电动机机壳表面温度应不超过80℃，轴承的温度应不超过95℃

4、电动机应经常保持清洁、干燥、通风良好，进风口与出风口必霜保持畅通。

5、运行中电动机出现冒烟、剧烈振动、异常声音、特殊气味、转速明显下降；负载设备出现故障；发生人身触电时应立即断电停机。

1, the motor should start immediately after closing, reach normal speed and smooth operation, if not, immediately cut off the power supply, check and troubleshoot.

2, after starting, pay attention to observe the motor transmission device, load machinery, voltmeter and ammeter, if there is an abnormal phenomenon should immediately stop.

3, the motor no-load continuous start generally not more than 4 times, running to hot stop after continuous start not more than 2 times, otherwise easy to burn the motor.

4, according to the power grid capacity, load size and motor power, reasonable choice of starting mode, more high-power motor should use a triangle method or step-down starting.

operation

1, the deviation between the power supply voltage and the rated voltage does not exceed ±5%, and the three-phase voltage imbalance does not exceed 1.5%.

2, the motor running current shall not exceed the rated current on the nameplate, the three-phase current unbalance shall not exceed 80%, otherwise it will cause the motor to heat or even burn.

3, with a thermometer to measure the motor housing surface temperature should not exceed 80 ° C, bearing temperature should not exceed 95 ° C

4, the motor should always be kept clean, dry, well ventilated, the air intake and air outlet must be kept smooth.

5, the operation of the motor smoke, violent vibration, abnormal sound, special smell, speed decreased significantly; Load equipment failure; In case of electric shock, power off and stop immediately.
