WEG Australia has released an updated range of flameproof Ex d motors along with the Ex n products, available in high and low-voltages.
The d range covers outputs from 0.18kW to 330kW in two, four, six, eight and 10 pole speeds, to 1100V in frames 90 - 355. The range is suitable for connection to 50Hz and 60Hz supplies.
The low-voltage Ex n certification covers outputs from 0.37kW to 330kW dependent on speed and is available in two, four, six, eight and 10 pole speeds in frames 90 - 355.
The Ex n motors are certified to 1100V for 50Ω and 60Hz supplies. For high-voltage Ex n products the certifications covers voltages to 6.6kV in frame sizes 315 - 630 in two, four, six, eight and 10 pole speeds.
The certification for low voltage Ex n and Ex d products includes use with VFDs, the fitting of bearing and winding RTDs, anti-condensation heaters and IP55, 56 and 65 protection.
