Manufacturer of motor and drive technology manufacturer, WEG, is presenting its latest drive solutions at this year's Ligna trade fair in Hanover (May 22-26). New geared motors in the WG20 series, with torque ratings from 820 to 1550Nm, add two more frame sizes to the product family, which presently includes helical, parallel-shaft and helical bevel gear units with sturdy pressure-cast aluminium housings and torque ratings from 50 to 600Nm.
These new, high-performance gear units are made from grey cast iron, and like the other models in the series, are available with energy efficiency ratings up to IE3. Standardised mounting dimensions allow them to be integrated into a wide variety of applications worldwide.
Other featured items on the WEG stand include low-profile motors for the woodworking industry from WEG subsidiary AKH. As a provider of drive technology, WEG is presenting their energy-efficient low voltage motors in the W22 series with energy efficiency ratings up to IE4 in both standard and explosion-proof versions, as well as automation products such as variable speed drives, soft starters and low-voltage switchgear.
Housings of the new WG20 geared motors are fabricated as monolithic structures, making them especially sturdy and torsionally stiff. In addition, the weight-optimised WG20 geared motors are highly energy efficient. The gear units feature a two or three-stage design for very low losses over a wide range of gear ratios, while their redesigned tooth geometry also provides very precise power transmission over the entire speed range.
