An updated general industrial duty motor portfolio from WEG

WEG has updated its portfolio of standard industrial motors to incorporate advanced technology. This has resulted in the introduction of three new motor series: the W40, W50 and W60. The motors collectively cover the power range from 90 to 4,250kW (50 and 60Hz).

The design has been optimised to make the motors more compact than their predecessors, with lower weight, smaller dimensions and a reduced footprint. With sturdy, innovative grey cast iron housings, they are suitable for use under extremely adverse conditions and assure low noise and vibration levels.

Optimised rotor and stator laminations, together with improved motor cooling give an especially high power density.  

The two-pole and four-pole motors in the W60 series are available in frame sizes from IEC450 to IEC560, with rated power from 800 to 4,250 kW and rated voltage from 2,300 to 10,000V.

The motors are available in three configurations: open and self-ventilated (IC01, WP-II), closed and air/air-cooled (IC611, TEAAC) and closed with air/water heat exchanger (IC81, TEWAC).

The W60 motors are designed for continuous use and are easy to install and commission. They are also suitable for use with medium-voltage frequency inverters as standard motors with no speed restrictions due to critical vibration speeds.

The W50 series (illustrated) is very similar to the W60 series in design and construction, featuring a compact and sturdy grey cast iron frame and high power density. W50 motors with two to twelve poles are available in frame sizes from IEC315 to IEC450, rated power from 90 to 1,280kW, and rated voltage from 440 to 6,600V.

The open drip-proofed (ODP) W40 motors with two, four or six poles are the smallest members of the standard industrial motors family and are only suitable for applications where dirt and moisture are not factors. They are available in frame sizes from IEC280L to IEC450 with rated power from 250 to 1,650kW for low and medium voltages.
