WEG, a leading global manufacturer of motor and drive technology, is launching the WG20, a new range of highly versatile modular geared motors that offer worldwide interchangeability and up to 96% energy efficiency at Hannover Messe 2016 (25 – 29 April, Stand F11 in Hall 15). The new geared motor will enable users across a wide range of industrial applications requiring precise and reliable power transmission to increase the energy efficiency of systems in their plants significantly, reducing associated energy costs. Other highlights will include the new explosion-proof W22Xe motors for increased-safety applications compliant with IEC 60079-7:2015 and the CWB series of contactors for nominal operating currents up to 80 A.
Developed in cooperation with gear technology specialist, Watt Drive, the WG20 comes in standardised mounting dimensions to suit both new and existing drive systems, ensuring ease-of-installation and flexibility when retrofitting. It is designed to cover virtually all international supply voltages thanks to internal voltage switching, which makes it easily interchangeable.
Available in energy efficiency classes up to IE3, the motors feature an optimised design, with the pinion directly mounted on to the motor shaft resulting in a two-stage gear unit (in place of the commonly used three-stage unit). Fewer stages means reduced friction, which translates into lower power and heat dissipation and thus more efficiency. Additionally, the improved gear geometry featuring optimised gear teeth and high quality ground gear parts ensure low-loss power transfer and low noise levels, along with reliable performance and extended service life.
“The WG20 – the first WEG-branded geared motor product line – brings together Watt Drive’s high R&D and manufacturing competence and WEG’s motor expertise, which is supported by a global sales and service network,” says Klaus Sirrenberg, Director Low Voltage Products, WEG. “By adopting smart design and optimised production processes, we have developed a top-quality geared motor range which fulfils all requirements of modern drive systems across a wide range of industrial applications around the world.”
The WG20 is built with helical, parallel-shaft and helical bevel gear units with rugged pressure-cast aluminium housings and is suitable for most industrial applications requiring torque ratings between 50 and 600 Nm.
Besides the WG20 range, WEG’s new W22Xe has been designed to meet the growing demand for more cost-effective classified area equipment in industries such as oil and gas, chemical and pharmaceutical. In line with WEG’s commitment to assist motor users boost energy efficiency, the W22Xe line is available in both IE2 and IE3 energy efficiency versions and – unlike most Ex e motors available on the market – has certification which permits them to be operated in combination with a variable speed drive (VSD).
