                        4. The conditions of use of the motor

                        4.1The motor uses environmental conditions

                        4.1 .1Ambient air temperature changes with the seasons, generally not more than -15 ~ +40

                        4.1.2 Environmental atmospheric pressure 80 ~ 110Kpa

                        4.1.3Altitude not more than 1000m

                        4.1.4Ambient air maximum relative humidity of not more than 95% (when the temperature is +25 )

                        4.1.5Working in the explosion, the lower limit between the flammable gas, steam, mist, dust or fiber and air and other forms of explosion with the risk of coal mine mining face.


                        4.2Electrical conditions for motor use

                        4.2.1 Rated frequency: 50HZ,Synchronous speed 3000r / min, 1500r / min, 1000r / min, 750r / min, 600r / min

                        4.2.2 Rated voltage: 380.660.1140.380/660.660/1140.Allow full pressure to start directly.

                        4.2.3 The motor quota is the continuous working standard, the working type is S1.
