Y3系列电动机是全封闭，自扇冷式鼠笼型三相异步电动机，它是取代Y,Y2系列跟新换代的产品。Y3系列电动机较Y，Y2系列效率高，起动转矩大，防护等级(IP54),提高了绝缘等级(F级）B级考核，其电机结构更加合理，外形新颖美观。电机冷却方式为IC411.安装尺寸及功率等级完全符合IEC标准（与Y系列相同)Y3系列电动机为一搬用途的电动机，适用于无特殊要求的各种机械设备，Y3系列电动机额定电压为380V,额定频率为50HZ，3KW以下为y接法，4kw以上为△接法。环境温度不超过40℃，海拔不超过1000M。 （Y3 series motors are fully enclosed, self-cooled, squirrel-cage three-phase asynchronous motors, which replace Y,Y2 series and new generation products.Compared with Y and Y2 series, Y3 series has higher efficiency, higher starting torque, higher protection grade (IP54), and higher insulation grade (F grade) and grade B examination.Motor cooling method is IC411. Installation size and power grade are fully in line with IEC standard (same as Y series). Y3 series motors are one-move motors, suitable for all kinds of mechanical equipment without special requirements.Environment temperature is not more than 40 ℃, altitude does not exceed 1000 m.）
