WEWE Series Three-Phase Asynchronous Motor

Standard Induction Motors WOLONG WE

WE is Wolong's base platform of low-voltage induction motors; WE3, WE4 and WE5 differ only in efficiency level — IE3 and IE4 to IEC 60034-30-1, IE5 to IEC 60034-30-2. Frames 63–355, 0.18–375 kW, 2–8 poles, 380 V, IP55, class F insulation, IC411 cooling, IEC mounting dimensions. Aluminium frames for sizes 90–160 (removable feet) and cast iron for 80–355 (fixed feet). Sizes up to H180 use sealed-for-life bearings, H200 and above are regreasable. On inverter supply the permissible speed range is 10:1 for variable-torque and 2:1 for constant-torque loads.
