Under the motto “EQ³ Energy Intelligence = Energy Efficiency. Smoothness. Lifetime.”, innovative technology sector company ZEITLAUF^® brings together all the elemental performance features of its products.

The town of Lauf an der Pegnitz, 20th of April 2009 – The global demand for energy is growing. Energy prices steadily rise. Increasing consumption of fossil fuels accelerates the process of climate change. This is forcing industry to invest in measures for increasing energy efficiency. ZEITLAUF^® took this trend seriously years ago and factored it into its drive solutions. Research and development work is based on three important performance features that are brought together under the motto “EQ³ Energy Intelligence = Energy Efficiency. Smoothness. Lifetime.”. These particular gear motor attributes go a long way to making ZEITLAUF^® one of the key players in the field of drive technology:

1. Energy efficiency
At ZEITLAUF^®, energy efficiency has been a priority throughout the entire production process and the life cycle of its gear motors for years. High performance and extremely high efficiency rates make it possible to use motors that are very much smaller and that use decidedly less energy. With the development of the EtaCrown^® angle gearhead incorporating crown wheel technology, ZEITLAUF^® has provided proof that the company is forward-looking when it comes to “energy saving gear motors”. Owing to its optimum efficiency rate of in excess of 85%, this highly efficient angle gearhead requires considerably less energy than a worm gear requires to achieve the same output. This results in considerable energy savings from using smaller electronics components and switching power supply units as well as smaller but more powerful motors. Looking at the life cycle costs, i.e. the entire costs over the lifetime of the products, EtaCrown^® saves more than 45% in single shift operation alone. Less heat generation means no expensive shielding is required. Symmetrical geometry means that storage costs are lower and the omission of the flange / recesses provides yet more savings.

2. Smoothness
Gear motors from ZEITLAUF^® stand out for their unusual quiet running properties. Tests conducted at certified noise laboratories confirm that these gear motors always come top in terms of low noise levels and noise reduction. This smoothness is achieved by a combination of intelligent toothing technology and precision manufacture of highest quality gear parts. With the NoiselessPlus planetary gearhead, ZEITLAUF^® has succeeded in developing one of the smoothest of all planetary gearheads available on the market today. Planetary wheels made of high-quality plastics are an essential element of the smoothness of this range. The angled toothing makes sure that meshing is even and thus enables great power to be transmitted. Producing the inner toothing by gauging ensures ultimate precision. Cross-grinding inside the plastic planetary wheel bearing bores guarantees that the required lubricant is always optimally distributed. Placing the planetary wheels in a bearer cage that rests on ball bearings both sides means that not only can NoiselessPlus cope with much higher radial loads than other gearheads of its size, it can also maintain its excellent running characteristics even under radial stress.

3. Lifetime
Amazing efficiency rates, the use of high-quality toothing materials, optimised gearing plus decades of engineering expertise all contribute to ensuring that ZEITLAUF^® gear motors have above average lifetime. This can only be achieved in combination with a quality management system that comes into effect right at the beginning of the development work and is effective throughout all phases of the production cycle and life cycle of the products. Specially developed production machinery, sophisticated test procedures, intensive long-term tests as well as ongoing assessment and documentation of results and findings constantly increase the quality of our development work and the lifetime of these gear motors.

“Given the current economic situation, the subject of energy efficiency is now more important in world markets than ever before. Because efficiency is of economic as well ecological significance for the industry”, says Thomas Horz, Managing Director of the company. “The industry has major options for using energy more efficiently, thus reducing energy costs. Our gear motors can make a major contribution to this. This not only brings the company improved efficiency, it also provides more ability to compete at international level and safeguards jobs. So energy efficiency pays – both in terms of our planet and our economy.”


Comprehensive product range
ZEITLAUF^® offers a wide range of products and services.

• 3,573 different drive solutions – based on a modular system principle: These are available on the basis of planetary, angle and spur gearheads in first-class quality. With a unique power density and application breadth.
• "Assembling on demand": Fast and individual combination of the required components in top perfection.
• 48 hours service: After an order has been received, the tailor-made drive is ready for dispatch within 48 hours (for quantities of up to 20 units).
• Keep-Word-Warranty: ZEITLAUF^® is taking unusual steps with its unique warranty promise. It includes replacement or repair of a faulty gearhead motor twice in a year, and the preparation of a fault protocol for the reason for the fault (prepared for every device returned). If there is an excessive load on the gearhead motor, it is replaced by a more powerful solution and the price set off completely against that of the original drive.
