Motors meet 'Efficiency 1' standard
Baldor has launched a complete range of IEC frame motors meeting the new 'Efficiency 1' standard, backed by a stocking service from the company's new European support hub in Bristol.

Low inertia motors drive motion control
Baldor has launched a new range of brushless servo motors for precision motion control applications, based on rare-earth neodymium iron boron magnets.
The new range is a development of Baldor's established Super-E motors which were designed to meet the USA's EPACT standard, and which achieve exceptional efficiencies - in some cases over 96%.
A wide range of metric size Super-E motors are now available extending from IEC 80 frames for the sub 5kW products, up to IEC 355 frames - which cover ratings well beyond 90kW and into the high power markets where Eff.1 levels are set by WIMES*.
The stock service also includes a choice of B3 foot-, B5 flange- or B14 face-mounting arrangements.

Baldor will be publicly showing some innovative new products for the first time at PPMA 2001, including a range of servo motors designed to withstand high pressure cleaning
European industry is being encouraged to install Eff.1 rated motors by governments - as part of their Kyoto commitments - through a mix of incentives and legislation such as the UK's forthcoming Climate Change Levy (CCL) and Enhanced Capital Allowance (ECA).
However, high efficiency motors come with a capital cost premium, which can deter potential purchases, and so Baldor is supporting the new products with free analysis software to help end users understand the underlying rationale.
Called SavePlus, the free software provides an analysis of the true costs of ownership of a motor, which includes its electricity consumption costs.
In continuous process industries, most electric motors consume their own capital cost in electrical energy within four months.
Baldor's software package allows users to feed in their own motor ratings, operating profiles and energy costs to see exactly what effect the higher efficiency will have for their exact application.
The new Super-E metric range builds on many years of experience that Baldor has in designing and manufacturing ultra-high efficiency motors, resulting in numerous special features.
These include over-rating by a factor of 1.15 (service factor) to assure reliability, the use of inverter spike resistant magnet wire and optimised insulation materials that can withstand peak voltages to 2kV.
Together, these and other attributes allow Baldor to offer an industry-leading three year warranty on all Eff.1 models.
"For a majority of end users, the outlay on a premium efficiency motor equates to just 10-15% of annual energy consumption, before taking into account any local European tax incentives", says Robin Cowley, Baldor's Industrial Products Manager.
"Analysis demonstrates that the case for installing Eff.1 motors is indisputable - even for organisations that operate electric motor-driven processing for relatively few hours a day".

*Backgrounder To be graded Eff.1 - which is the premium efficiency level (of three) that qualifies for the UK's tax incentives - motors must meet minimum efficiency standards as determined by CEMEP (European Committee of Manufacturers of Electrical Machines and Power Electronics) for 2- and 4-pole motors from 1.1 to 90kW, and WIMES (Water Industry Minimum Efficiency Standards) from 90-400kW and for motors up to 8-pole.
Efficiency ratings vary according to power, but as an example, for 4-pole motors at 5.5 and 55kW, they are: "89.2% and "94.2% respectively for Eff.1, and "85.7% and "93% for Eff.2.
Eff.3 figures are anything below Eff.2 levels. Request a free brochure from Baldor UK ...
