Explosion-proof motors hit deck

THE OIL and gas industry is in particular focus for ABB’s new range of explosion proof motors.

According to ABB’ s marketing manager Chemicals, Oils and Gas Drives, Motors and Machines, Jean-Charles Guilhem, who was visiting Australia recently, the motors are designed to meet the requirements of Australian Standards, meeting the highest efficiency level, High Efficiency.

“We are here to finalise certification for Australian Standards,” Guilhem told PACE.

The Australian certification will be a staggered process beginning this quarter with the Non-Sparking Standard, then the Flame-Proof Standard later this year. Meeting the Pressured Standard and the Increased Safety Standard will be determined on a case-by-case basis.

Guilhem said its research showed that Australia was the fourth biggest gas producer in the world, and as such had become a very important market to ABB for such motors.

“Australia is at the beginning of tremendous growth in this area [of gas production],” he said.

Guilhem and colleague Dr Luigi Bubba, sales and marketing manager AC Machines - DC Motors travelled to NSW, Victoria and WA to speak to customers about its new range of M3000 Ex motors for hazardous environments.

ABB’s vice-president, Electrical Motors (Australia) Sean Stove, said the temperature in the winding of the new motors had been lowered by 3-5°C, which represented an increased life-time of 30-50%.

Stove said the design had improved efficiencies that had a significant impact on running costs. For example, a 90kW ABB motor rated ‘High Efficiency’ could save almost $7800 over its life cycle compared to a motor with a “minimum efficiency’ rating, assuming continuous duty at a tariff of $0.08/kWh and a 10 year service life.

“Sites such as refineries can have several thousand Ex motors, so significant amounts can be saved using high efficiency motors,” Stove said.
