General introduction
Y2 series three-phase asynchronous motors, created with new tactics, are renewed and upgrading products determined by Y series motors.
Y2 series motors are in obdurate design and fan cooled variety, squirrel cage style and novel in design and style and wonderful in appearance, compact structure, reduce noise, high efficiency, massive torque, superb beginning efficiency, straightforward upkeep, and so forth.. This series motors adopt F class insulation and developed against the insulation program assessing strategy in accordance of international practice.
Y2 series motors is usually extensively utilized to numerous of driving equipments including machine equipment, blowers, pumps, gearboxes, compressors, transporters, agricultural machines and so forth.
Working circumstances
Ambient temperature: 15 40 . Altitude: no higher than 1000 meters from sea level.
Rated voltage: 380V. Rated frequency: 50Hz,
Connection: Y connection is adopted for motors under 3KW (3KW included) and connection is adopted for other people over 4KW( 4KW included). Working ration: steady working method (S1).
F class Insulation, the temperature rising on the stator winding examined at 80K(by resistance method). Safety grade: about the primary body is IP54, within the terminal box can reach IP55. Cooling method: Ic411.
The followers are normally made of strengthen plastics other than 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 form by stret-ching with cold rolled steel plate to develop into substantial mec hanical strength.
