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.
