Electric motors, gear units & systems

12 October 2017

At this year’s SPS IPC Drives WEG is launching its expanded WG20 geared motors portfolio with helical, parallel-shaft and helical bevel gear drives for rated torques up to 5000Nm.

The housings of the new gear units are manufactured from grey cast iron and are especially sturdy. This makes them ideal for demanding applications within the steel industry plus the heavy-duty industrial sector, amongst others. In combination with high-performance motors available in energy efficiency classes up to IE4, the geared motors provide a lot of power in a compact form.

Also on display at Stand 250 located in Hall 3, are switchgear cabinets manufactured by WEG’s Spanish subsidiary Autrial, which are being showcased in Germany for the first time. From its site in Valencia, the Brazilian drive technology manufacturer supplies the European market with complete industrial switchgear cabinet systems. In addition, WEG is exhibiting one of the industry’s most comprehensive portfolios of energy-efficient electric motors, as well as the current automation products for the European market. This includes variable-speed drives, soft starters and low-voltage switchgear.

“Thanks to the expansion of the WG20 geared motor portfolio, we are now able to handle applications with relatively high torque requirements. In these demanding applications, the robust construction, manufacturing quality and power density of our geared motors are especially beneficial”, says Wilmar Henning, Managing Director of WEG in Germany.

Energy-efficient geared motors

A smart pinion concept allows the gear units of the WG20 series to be made in two-stage or three-stage versions over a wide range of gear ratios. This results in very low losses, thus making the gear units very energy efficient. The variant-optimized tooth concept, also makes possible high output speeds and allows for the implementation of a large speed range with all gear unit frame sizes. What’s more, stringent quality standards in the gearwheel production process ensures smooth operation and longer service life of the gear units. The high quality-finish makes the geared motors suitable for even the most demanding applications, and the standard mounting dimensions allow them to be easily integrated into a wide variety of applications worldwide. The WG20 geared motors need very little maintenance and are extremely reliable ensuring machine and system productivity.

Rounding out the system

In 2015 WEG acquired the Spanish switchgear cabinet builder Autrial, whose headquarters are in Valencia. At this location 139 employees produce application-specific low-voltage and medium-voltage switchgear cabinet systems for a wide variety of applications, including power generation, renewable energy sources, mechanical engineering and petrochemical. Due to being manufactured in Europe these products can be offered to the market with quicker delivery times, from design to manufacture and commissioning, all within a matter of weeks.

“WEG has been manufacturing complete switchgear cabinet systems in Brazil for a long time. Through the acquisition of Autrial we are now able to do this in Europe. This also allows us to significantly expand our portfolio of automation products and services for the European market plus it strengthens our position in the area of integrated drive solutions”, says Wilmar Henning.

All switchgear systems are manufactured in accordance with the highest quality standards and can be deployed not only in Europe, but also in North America (UL and CSA) and Russia (EAC), as well as explosion hazard areas (ATEX). Autrial gives WEG full control over the entire life cycle of switchgear cabinets, from planning and engineering through production and programming to installation and service. WEG services the entire EMEA region from Spain.
