General introduction
Y2 series three-phase asynchronous motors, developed with new approaches, are renewed and upgrading goods based on Y series motors.
Y2 series motors are in obdurate style and design and fan cooled type, squirrel cage kind and novel in style and design and wonderful in physical appearance, compact construction, lower noise, higher efficiency, substantial torque, fantastic commencing effectiveness, effortless servicing, etc.. This series motors adopt F class insulation and designed towards the insulation procedure assessing technique in accordance of international practice.
Y2 series motors might be broadly applied to a variety of of driving equipments for example machine equipment, blowers, pumps, gearboxes, compressors, transporters, agricultural machines and so forth.
Operating situations
Ambient temperature: 15 forty . Altitude: no larger than one thousand meters from sea degree.
Rated voltage: 380V. Rated frequency: 50Hz,
Connection: Y connection is adopted for motors beneath 3KW (3KW integrated) and connection is adopted for others above 4KW( 4KW incorporated). Functioning ration: steady working method (S1).
F class Insulation, the temperature rising from the stator winding examined at 80K(by resistance technique). Protection grade: over the main physique is IP54, over the terminal box can attain IP55. Cooling method: Ic411.
The fans are usually made of strengthen plastics aside from that for frame sizes H315 as much as 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 become high mec hanical power.
