YB2 explosion-proof motor is in conformity with technical data of JB/T7565.1(Frame63-355), GB3836.1
3.2.1 The environment air temperature varies with seasonal variation, does not exceed 35 (under coal mine) or the 40º C (factory), air minimum temperature is -15º C.
3.2.2 Elevation not more than 1, 000 meters
3.2.3 The maximal relative humidity of ambient air does not exceed 95% (while the temperature is 25º C) (down coal mine) or the maximal relative humidity of the wettest monthly averages is the monthly averages minimum temperature's turn not to overtop 25º C at the same time for 90% (the factory uses).
3.2.4 Fixed voltage: 220V, 380V, 660V, 220V/380V, 380V/660V.
3.2.5 Fixed frequency: 50Hz
3.2.6 The electric motor quota is the continuous quota taking that continuous duty type makes (S1) as criterion, allows full pressure to get it in gear.
3.2.7 The electric motor's insulation class is F level. The stator winding gets the temperature rise(Electric resistance method) examining according to 80K(2 pole and 4 pole of frame 315L, and frame 355 allowed to be examined according to 105K), bearing temperature does not exceed 95º C.
