Basic introduction
Y2 series three-phase asynchronous motors, produced with new methods, are renewed and upgrading goods based upon Y series motors.
Y2 series motors are in obdurate style and design and fan cooled variety, squirrel cage kind and novel in design and nice in appearance, compact structure, decrease noise, high 
efficiency, big torque, exceptional starting performance, straightforward maintenance, etc.. This series motors adopt F class insulation and designed towards the insulation system assessing system in accordance of worldwide practice.
Y2 series motors may be widely applied to numerous of driving equipments such as machine resources, blowers, pumps, gearboxes, compressors, transporters, agricultural machines and so forth.
Operating circumstances
Ambient temperature: 15 forty . Altitude: no increased than 1000 meters from sea degree.
Rated voltage: 380V. Rated frequency: 50Hz,
Connection: Y connection is adopted for motors under 3KW (3KW integrated) and connection is adopted for some others above 4KW( 4KW incorporated). Working ration: steady working method (S1).
F class Insulation, the temperature rising in the stator winding examined at 80K(by resistance approach). Safety grade: within the key entire body is IP54, to the terminal box can attain IP55. Cooling technique: Ic411.
The fans are commonly created of strengthen plastics besides that for frame sizes H315 up to H355 are made of aluminium-alloy or stamped with steel plate. Alt fan cowis are taken into form by stret-ching with cold rolled steel plate to come to be large mec hanical power.
