Basic introduction
Y2 series three-phase asynchronous motors, produced with new strategies, are renewed and upgrading goods based upon Y series motors.
Y2 series motors are in obdurate layout and fan cooled type, squirrel cage form and novel in style and design and nice in appearance, compact structure, reduced noise, large efficiency, significant torque, excellent starting functionality, simple servicing, etc.. This series motors adopt F class insulation and intended towards the insulation method assessing approach in accordance of international practice.
Y2 series motors is usually broadly utilized to several of driving equipments for instance machine resources, blowers, pumps, gearboxes, compressors, transporters, agricultural machines and so on.
Working conditions
Ambient temperature: 15 forty . Altitude: no greater than one thousand 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 others over 4KW( 4KW included). Doing work ration: constant functioning system (S1).
F class Insulation, the temperature growing with the stator winding examined at 80K(by resistance process). Protection grade: to the key physique is IP54, around the terminal box can attain IP55. Cooling technique: Ic411.
The followers are commonly produced of strengthen plastics besides 
that for frame sizes H315 up to 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 develop into substantial mec hanical power.
