Common introduction
Y2 series three-phase asynchronous motors, developed with new tactics, are renewed and upgrading products determined by Y series motors.
Y2 series motors are in obdurate style and fan cooled variety, squirrel cage variety and novel in design and style and wonderful in appearance, compact construction, reduced noise, large efficiency, substantial torque, superb starting functionality, uncomplicated maintenance, and so on.. This series motors adopt F class insulation and intended towards the insulation process assessing approach in accordance of international practice.
Y2 series motors may be widely applied to various of driving equipments like machine resources, blowers, pumps, gearboxes, compressors, transporters, agricultural machines and so forth.
Operating conditions
Ambient temperature: 15 40 . Altitude: no greater than 1000 meters from sea level.
Rated voltage: 380V. Rated frequency: 50Hz,
Connection: Y connection is adopted for motors beneath 3KW (3KW included) and connection is adopted for some others over 4KW( 4KW integrated). Working ration: steady operating method (S1).
F class Insulation, the temperature 
increasing with the stator winding examined at 80K(by resistance approach). Protection grade: on the main physique is IP54, to the terminal box can reach IP55. Cooling strategy: Ic411.
The supporters are normally made of strengthen plastics apart from that for frame sizes H315 as much as 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 turn out to be large mec hanical strength.
