5.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 ~ +35 ℃

4..1.2 Altitude not more than 1000m

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

4.2Electrical conditions for motor use

4.2.1 Rated frequency: 50HZ

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.

4.2.4 The stator winding of the motor adopts F-class insulation system or H-class insulation system. Stator winding temperature rise (resistance method) by 85K assessment (including frame number 315L 2,4 pole, allowing 105K assessment).

Note: When the environmental conditions and electrical conditions used in the motor do not comply with the requirements of regulation 3.1.3.2, see the motor nameplate and the label.

5. Structural description

5.1 The protection rating of the motor housing is IP55.

5.2 The structure and installation of the motor are IMB3, IMB5

5.3 The main body of the motor shell material: base made of steel, with a high impact resistance, collision capacity, the remaining parts are not less than HT250 shell made of gray cast iron.

5.4 The motor has one end of a cylindrical shaft extending by a resilient coupling or a spur gear.

5.5The motor junction box is located at the top of the base, and the junction box is a rubber cable, which has three or six terminals for single voltage or dual voltage. The junction box inlet is divided into single inlet (frame number H132 ~ 315) and double inlet (frame size H250 ~ 315) for connecting the cable. If the motor uses double inlet junction box, and the external cable with a single port into the line, the other inlet of the ring must be blocked with metal plugs, and sealed on both sides of the ring with not less than 2mm thick metal gasket sealing , And then use the junction box bucket to press it on the seal ring, to ensure that the junction box explosion-proof performance. There is another copper grounding screw or steel galvanized bolt in the junction box for grounding.
