General introduction
Y2 series three-phase asynchronous motors, formulated with new strategies, are renewed and upgrading solutions according to Y series motors.
Y2 series motors are in obdurate style and fan cooled kind, squirrel cage variety and novel in layout and wonderful in look, compact construction, reduced noise, large efficiency, massive torque, superb beginning effectiveness, simple upkeep, and so on.. 
This series motors adopt F class insulation and developed towards the insulation system assessing method in accordance of international practice.
Y2 series motors can be broadly utilized to many of driving equipments including machine equipment, blowers, pumps, gearboxes, compressors, transporters, agricultural machines and so forth.
Working conditions
Ambient temperature: 15 40 . Altitude: no increased than 1000 meters from sea degree.
Rated voltage: 380V. Rated frequency: 50Hz,
Connection: Y connection is adopted for motors beneath 3KW (3KW included) and connection is adopted for many others over 4KW( 4KW integrated). Doing work ration: constant operating program (S1).
F class Insulation, the temperature growing of the stator winding examined at 80K(by resistance process). Safety grade: on the major physique is IP54, on the terminal box can attain IP55. Cooling method: Ic411.
The supporters are frequently produced of strengthen plastics besides that for frame sizes H315 up to H355 are manufactured of aluminium-alloy or stamped with steel plate. Alt fan cowis are taken into shape by stret-ching with cold rolled steel plate to turn out to be large mec hanical strength.
