GENERAL INTRODUCTION

The Series Y2 motors (center height 80- 355mm, 0.18- 315kw) are totally enclosed fan cooled, three- phase, squirrel cage induction motors. Series Y2 3- phase low voltage 3- phase induction motors of basic series. s up to the international standard in the nineties.

As compared with Series Y, the Series Y2 motors feature high efficiency and starting torque, and they also characterized by such outstanding features as: protection degree in IP54, insulation class in F (test in class B), low noise (test at load), better structure and new artistic outline. Its cooling method is IC411. The rated output and the mounting dimensions are fully conformed to the standard IEC and DIN 42673 (the same as series Y). Series Y2 are general purpose motors suitable for driving various kinds of machines or equipment without special requirement. Series Y2 are rated at 380v, 50Hz, Y- connection for motors up to 3kw, DELTA connection for 4kw and above. The ambient temperature is not exceeding 40 centigrade degree. The altitude is not over 1000 meters above sea level. The duty is continuous way (S1).

For series Y2 motors, there is usually one shaft extension, but two shaft extensions with terminal box on top of the frame are available on special order. Motors for special voltage, frequency or for humid tropic services (type TH motors ) or any other particular services are available on request.
