Basic introduction
Y2 series three-phase asynchronous motors, formulated with new tactics, are renewed and upgrading goods dependant on Y series motors.
Y2 series motors are in obdurate style and fan cooled kind, squirrel cage form and novel in design and style and wonderful in look, compact construction, lower noise, large efficiency, substantial torque, great starting effectiveness, straightforward servicing, etc.. This series motors adopt F class insulation and designed against the insulation method assessing strategy in accordance of global practice.
Y2 series motors may be widely applied to several of driving equipments for example machine tools, blowers, pumps, gearboxes, compressors, transporters, agricultural machines and so on.
Working circumstances
Ambient temperature: 15 40 . Altitude: no larger than 1000 meters from sea degree.
Rated voltage: 380V. Rated frequency: 50Hz,
Connection: Y connection is adopted for motors below 3KW (3KW included) and connection is adopted for others above 4KW( 4KW integrated). Functioning ration: constant operating process (S1).
F class Insulation, the temperature growing of the stator winding examined at 80K(by resistance method). Protection grade: over the principal entire body is IP54, about the terminal box can reach IP55. Cooling process: Ic411.
The supporters are typically manufactured of strengthen plastics other than that for frame sizes H315 up to H355 are made of aluminium-alloy or stamped with steel plate. Alt fan cowis are taken into form by stret-ching with cold rolled steel plate to become large mec hanical power.
