Common introduction
Y2 series three-phase asynchronous motors, produced with new methods, are renewed and upgrading merchandise depending on Y series motors.
Y2 series motors are in obdurate style and design and fan cooled style, squirrel cage variety and novel in style and great in physical appearance, compact construction, reduced noise, substantial efficiency, huge torque, outstanding starting overall performance, uncomplicated servicing, etc.. This series motors adopt F class insulation and intended against the insulation process assessing method in accordance of worldwide practice.
Y2 series motors is often extensively applied to numerous of driving equipments for instance machine resources, blowers, pumps, gearboxes, compressors, transporters, agricultural machines and so on.
Working disorders
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 incorporated) and connection is adopted for others above 4KW( 4KW integrated). Operating ration: constant working process (S1).
F class Insulation, the temperature growing from the stator winding examined at 80K(by resistance approach). Protection grade: to the key entire body is IP54, to the terminal box can attain IP55. Cooling strategy: Ic411.
The followers are normally made of strengthen plastics aside from that for frame sizes H315 up to H355 are created of aluminium-alloy or stamped with steel plate. Alt fan cowis are taken into form by stret-ching with cold rolled steel plate to develop into large mec hanical strength.
