Description (1)Adopting new techniques,Y2 series three-phase asynchronous motors are the renducts of ewal and upgradingproducts of Y series. (2) Y2series motors are defined as totally enclosed fan cooling squirrel cage type. (3) adopt F class insulation,and is designed with assessing method for in sulation system according to internationalpractice,which geatly enhances motor's safety an reliability,reached an international advanced level of such kindof products. (4) IP54 degree of cover protection,IC417 cooling method,continuous duty(SI),380V rated voltage and 50Hz rated frequency. (5) For motor of 3KW and below,the stator windings are connected in Y,while for 4KW and above are in Δ.
