Low voltage motors for hazardous areas

Efficient motors deliver huge energy
savings and emission reductions
Continuously rising energy prices, the urgent need to cut
carbon dioxide emissions, and the introduction of standards
and regulations setting minimum efficiency levels have
boosted demand for high efficiency motors.
Motors for use in hazardous areas are subject to rigorous
safety requirements all over the world. By contrast, efficiency
requirements for these motors vary widely between markets:
some countries have tough requirements in force but others
still do not have mandatory minimum efficiency levels.
Nevertheless, motor users in all parts of the world are seeking
ways to cut costs and reduce their environmental impact,
and this has led to strong demand for efficient motors for
applications in hazardous areas. ABB meets this need by
supplying a range of high and premium efficiency motors for
hazardous areas. Efficient motors cost slightly more to
purchase, but the big energy savings that are possible can
make payback times very short. Other benefits include cooler
running, which helps to cut maintenance requirements and
extend the lifetime of key motor components.
With a full range of energy efficient motors for hazardous
areas and reliable support services available worldwide,
ABB is in a strong position to serve the needs of motor users
looking for ways to reduce their operating costs and meet
their environmental commitments.
Efficient motors cost slightly more to purchase but produce huge
lifetime savings in energy costs and CO

emissions.

The graph shows the savings that can typically be achieved by
selecting an efficient ABB motor rather than a less efficient product.
The calculations assume a running time of 24 h
/
365 days,
motor lifetime of 25 years, purchase price difference of 15% and
electricity costs of

The graph below shows that selecting a lower efficiency
motor because it costs less to purchase can be a very
expensive mistake. An efficient motor will cost slightly more
to buy, but the energy savings achieved over its lifetime
outweigh the additional purchase cost many times.
