The company LENZE located in the northern part of Germany was founded in 1947. Today LENZE is one of the leading manufacturers of mechanical and electronic drive technology.
About 2000 employees world-wide are working for the company. About 100 electronic engineers are designing electrical motors, gears, brakes, clutches and small drives and the electronic boards to control the drive systems. Beside the design the products are manufactured in two fabs located next to the design facilities. The products are sold to OEM and end customers that design and install or maintain automated machines and plants. Lenze products are sold worldwide, but the core markets are Germany and Europe.

One main product is a microcontroller based frequency inverter. LENZE wanted to reduce the price of the product to react to market pressure by replacing some 90 discrete components by one mixed signal ASIC. Currently 50 K units per year of the electronic board to be replaced are being produced. Size reduction will also allow Lenze to build smaller inverters in the future and open new markets.

The AE started at 03.01.1997 and ended at 02.28.98. The development costs were about 120 k¤. In this project Lenze learned how to specify mixed signal ASICs, was trained to use a common CAD system for design entry and simulation. The payback period for the investment we made for the ASIC is 1.5 - 2 years. The ROI is 400% for a product lifetime of 4 years. Within the new Inverter more EMC have been integrated. A size reduction of 60% and a cost reduction of about 30% could be realized.

To minimize risks during development beside the mixed signal ASIC a discrete and an integrated solution was done in parallel. Without FUSE it would not have been possible to do this simultaneously.
