General introduction
Y2 series three-phase asynchronous motors, formulated with new approaches, are renewed and upgrading products dependant on Y series motors.
Y2 series motors are in obdurate layout and fan cooled type, squirrel cage kind and novel in style 
and design and wonderful in physical appearance, compact construction, decrease noise, higher efficiency, massive torque, great beginning effectiveness, effortless upkeep, etc.. This series motors adopt F class insulation and built towards the insulation process assessing method in accordance of international practice.
Y2 series motors could be broadly applied to different of driving equipments including machine resources, blowers, pumps, gearboxes, compressors, transporters, agricultural machines and so forth.
Working situations
Ambient temperature: 15 40 . Altitude: no larger than one thousand meters from sea degree.
Rated voltage: 380V. Rated frequency: 50Hz,
Connection: Y connection is adopted for motors below 3KW (3KW integrated) and connection is adopted for many others above 4KW( 4KW integrated). Functioning ration: steady doing work system (S1).
F class Insulation, the temperature rising of the stator winding examined at 80K(by resistance technique). Safety grade: to the most important physique is IP54, to the terminal box can attain IP55. Cooling method: Ic411.
The fans are generally made of strengthen plastics apart from that for frame sizes H315 as much as H355 are created of aluminium-alloy or stamped with steel plate. Alt fan cowis are taken into shape by stret-ching with cold rolled steel plate to come to be high mec hanical strength.
