Y2 General Introduction Y2 series three-phase asynchronous motors,developed with new techniques, are renewed and upgrading products based on Y series motors. Y2 series motors are in total-sealed design and fan cooled type,squirrel cage type and novel in design and nice in appearance, compact structure.lower noise,high efficiency,large torque,excellent starting performance,easy maintaince, etc…This series motors adopt F class insulation and designed as the insulation system assessing method in accordance of international practice. Y2 series motors can be widly applied to various of driving equipments such as machine tool,blowers,pumps,gear boxes, compressors,transporters,agricultural machines and so on.
