"These new high efficiency, low noise and vibration hazardous area motors are designed to meet the toughest, most arduous operating conditions in the oil and gas and other industries", said Antonio Duarte, Managing Director of WEG Portugal.
"They feature a low running temperature and can be specified to operate in ambient temperatures of up to between -55 and +60C; as well as gaining ATEX certification, we are obtaining certification for marine use (GL, ABS or Lloyds), CCVE (GOST R) and IECEx".
The modular design of the WOGC/WOGB motor range, developed and manufactured in WEG's European factory in Porto, Portugal, is designed to provide optimum versatility to meet specification requirements in gas (Zone 1) and dust (Zone 21) hazardous areas, enabling the motor frame enclosure to be used with different sizes and types of terminal boxes.
The first model to be released is a 1500kW motor, which is suitable for voltages between 380 and 13800V, with a choice of 50 or 60Hz.
In addition, to ensure a long, reliable service life, it features thermal protection on windings and bearings, an IP65 rating and Class F insulation.
The standard configuration provides main and auxiliary terminal boxes on the top of the enclosure, with RHS cable entries and the motor is externally finished to paint standard 202E, RAL 7001.
Further options include a third auxiliary terminal box, a second power terminal box and terminal boxes specifiable on the right or left sides or flying leads.
A choice of IP protection standards is also available, as are service classes from S2 to S10.
In addition, an option for use with a frequency convertor enables power uptake to be matched to process needs for optimum energy efficiency.
