General introduction
Y2 series three-phase asynchronous motors, designed with new tactics, are renewed and upgrading products based on Y series motors.
Y2 series motors are in obdurate layout and fan cooled type, squirrel cage kind and novel in design and style and nice in visual appeal, compact framework, lower noise, substantial efficiency, large torque, exceptional commencing functionality, straightforward upkeep, and so on.. This series motors adopt F class insulation and built towards the insulation system assessing process in accordance of worldwide practice.
Y2 series motors might be extensively applied to many of driving equipments which include machine tools, blowers, pumps, gearboxes, compressors, transporters, agricultural machines and so forth.
Working circumstances
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 other people above 4KW( 4KW included). Operating ration: constant operating process (S1).
F class Insulation, the temperature rising with the stator winding examined at 80K(by resistance method). Safety grade: around the most important physique is IP54, on the terminal box can reach IP55. Cooling approach: Ic411.
The fans are normally manufactured of strengthen plastics other than that for frame sizes H315 up to H355 are produced of aluminium-alloy or stamped with steel plate. Alt fan cowis are taken into shape by stret-ching with 
cold rolled steel plate to come to be substantial mec hanical strength.
