3rd Quarter 2012Electrical switching & drive systems & components
The combined strength of the Zest WEG Group of companies will be on show at Electric Mining Africa 2012, with an integrated display of motor-related products and expertise. Jamie Wilson, marketing manager of Zest WEG Group, says, “The Zest WEG group is a leader in the supply of electric motors and drives, motor control panels, generator sets, energy solutions, and ancillary products and services. An outside stand is essential for showcasing a full range of our bigger items of equipment.”
Zest Electric Motors will showcase the motor drive combination of the WEG W22 electric motor coupled with its WEG CFW11 variable speed drive technology. WEG’s innovative three-phase W22 motor provides an energy efficient solution to reducing industrial energy consumption. The WEG CFW11 series of inverters includes state of the art technology for three-phase induction motor control and was developed to boost customer productivity. Also on show will be the WEG SSW7000 medium voltage soft starter, which provides start/stop control and protection for three-phase medium voltage induction motors in the 2.3 kV to 6.9 kV range.
The WEG W22X flameproof motor in the W22 mould includes gas groups IIA, IIB and IIC. Supplied in frame sizes from 71 and upwards, this ATEX/IECEx certified motor is designed to cope with the rigours of aggressive and explosive atmospheres, while delivering the added benefits of high efficiency, (IE2/IE3 energy efficiency rating); minimised noise and vibration; and low operating temperature.
