2 W22 Super Premium

www.weg.net
In the last two decades global energy consumption has increased by 50%, with the forecast that the next two decades will see the usage increase dramatically.
This increasing demand for electric energy to sustain global development requires constant heavy investment in power supply generation.
In addition to complex medium and long term planning, these investments rely on natural resources, which are becoming depleted due to constant pressures upon the environment.
As a reflection of this scenario, electric energy costs are spiralling and in comparison to other economic indicators, standing out negatively.
One of the main reasons for the global increase in power consumption is the industrial sector, which demands around 30% of the electric energy globally available. In industrial applications, electric motor driven systems represents around 65% of all energy consumption.
If we consider industrial and domestic applications, including appliances, in our analysis, the electric motor represents more than 40% of the total energy consumed globally.
Due to this increase it is more important now that products are manufactured with energy efficiency as the main driver.
Aware and concerned about this situation, several Governments are implementing
Minimum Energy Efficiency Performance
Standards in order to drive the use of highefficient equipment.
Europe is no different, and motor systems were earmarked as a priority target in the
Eco-Design Directive (2005), which has established requirements for Energy-using
Products: “EuP Directive”. As a result of that,
EU Mandatory Minimum Energy-Efficiency
Performance Standard (MEPS) for industrial electric motors came into force from July
2009.
With this situation in mind WEG presents its
W22 Super Premium efficiency motor line, exceeding the IE4 Efficiency Levels defined in
IEC Technical Specification
IEC/TS 60034-31 and draft IEC Standard
60034-30 edition 2.
The efficiency performance of these motors far exceeds the minimum efficiency level IE2 required by European legislation today, and the future required IE3, mandatory as from
2015. This enables the customer to reduce their Total Cost of Ownership (TCO) through the reduction of the energy consumption and to reduce their carbon footprint.

Running costs including energy usage
Industries Operating Costs
Industry requires water, steam, compressed air and electric energy to drive their manufacturing processes. These resources play a major part in a company’s results since they directly impact on the operating costs which are then reflected in the prices, affecting the bottom line and ultimate competitveness.
In a competitive market it is not always possible to reduce purchasing costs or to increase prices so other cost savings must be made. Focus s ing efforts on saving resources during production is one strategy to reduce costs and improve margins.
WEG has developed the W22
Super Premium efficiency motor to allow for significant savings in energy usage and give a more reliable motor for the required applications.
Total Cost of Ownership
When a company needs to buy a new electric motor, the acquisition cost can determine the purchase, however more consideration needs to be given to the total cost of ownership (TCO) including maintenance, installation and running costs which account for a large portion of that overall amount.
Typically applications do not run at full load all the time. Installing a VFD can help you save money by controlling the speed of your process and adjusting it to the specific load at any time. This is specifically true for variable torque applications like pumps and fans.

g
Increased lubrication intervals – less need for
maintenance interventions g
Low operating temperatures – increases the
insulation time, resulting in a longer lifespan g
Flexible terminal box design for frames 225 to
355 – the same design allows for lateral or
top-mount machines, reducing the motors
replacement inventory g
Solid and integrated feet – provides a tough
construction and enables easier installation
and alignment
Oversized and diagonally slip terminal box – g
provides fast and secure procedures, besides
more ergonomics
Provisions for vibration detectors – motors in g
frames 160 and above are fitted with flat surfaces
for vibration detectors g
New rubber drains – allows for easy motor
drainage at maintenance procedures, and can
provide high protection at harsh conditions
These items, combined with the assured energy savings, states the commitment of the
W22 Super Premium motors design with the TCO.

The chart above shows the efficiency comparison between the IE2 and IE3 efficiency levels determined by the IEC Standard 60034-30 and the new W22
Super Premium line efficiency, for 4-pole machines.
As motors usually run for thousands of hours every year, any gain in efficiency by replacing motors with higher efficiency versions, will translate into considerable savings which would pay for the investment in a few years and in some cases even months.
The Super Premium design, which presents from 20 to 40% less losses in comparison to the conventional motors, provides the world’s highest efficiency levels available for an induction electric motor.
Because of this, the investment for the replacement of installed motors by the W22 Super Premium efficiency motor will be repaid in a very short period of time, resulting not only on energy savings, but also on plant reliability and availability.
The energy savings will be even greater if the old motor has been subject to repairs during its lifetime, each repair can reduce performance by up to 1% of efficiency.
