General introduction
Y2 series three-phase asynchronous motors, formulated with new tactics, are renewed and upgrading products based upon Y series motors.
Y2 series motors are in obdurate layout and fan cooled style, squirrel cage type and novel in layout and wonderful in physical appearance, compact construction, lower noise, high efficiency, huge torque, excellent beginning effectiveness, straightforward servicing, etc.. This series motors adopt F class insulation and intended towards the insulation technique assessing process in accordance of global practice.
Y2 series motors could be widely applied to different of driving equipments like machine resources, blowers, pumps, gearboxes, compressors, transporters, agricultural machines and so forth.
Working circumstances
Ambient temperature: 15 40 . Altitude: no greater 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 others above 4KW( 4KW integrated). Functioning ration: steady working system (S1).
F class Insulation, the temperature rising of the stator winding examined at 80K(by resistance method). Safety grade: to the key physique is IP54, over the terminal box can attain IP55. Cooling process: Ic411.
The fans are generally manufactured 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 become substantial mec hanical strength.
