The WEG product portfolio previously consisted of helical, parallel shaft and helical bevel gear units with robust die-cast aluminum housings for nominal torques of between 50 and 600 Nm. The new WG20 universal geared motors for nominal torques of 820 to 1,550 Nm that form the centerpiece of WEG’s presentation at LIGNA add two sizes each to the still young product portfolio. The new, more powerful gear units are made of cast iron and, like the other models in the series, they are available in energy efficiency classes up to IE3. Market-compliant connection dimensions will enable them to be integrated into numerous applications worldwide.
The unicase design of the new WG20 geared motor housings is intended to make them particularly robust and torsionally stiff. What's more, the weight-optimized WG20 geared motors exhibit excellent energy efficiency. The two/three-stage gear units are designed with a large ratio range, so the losses are minimal. The new gearing geometry also ensures high-precision power transmission over the entire speed range. "WG20 geared motors are very easy to maintain and service," explains Klaus Sirrenberg, Managing Director of WEG subsidiary Watt Drive, which was in charge of developing the motors and manufactures them at the company’s Austrian site in Markt Piesting. "Their robustness and high-quality workmanship make them perfect for applications with demanding environmental conditions such as the woodworking industry," he adds.
Visitors to the WEG stand can also find out about AKH's robust K1F and K2F parallel shaft motors, which are ideal for bandsaw and circular saw plants, sawmills and stone saws. These three-phase asynchronous motors impress not only with their high power density and energy efficiency, but also their optimum stability in precision applications.
