Abstract

Sisme company (founded in 1957, presentely 953 people, 90 MEURO turnover in the fiscal year 1999) produces asynchronous electric motors and motor pumps in the following three main sectors: household appliances (dishwashers and tumble dryers), ventilation / air conditioning and reciprocating / scroll compressors for commercial and industrial refrigeration.

During the years Sisme reached the position of leader for the European market as independent manufacturer of motors producing them directly on customer requirements.

The company electronic expertise is substantially limited to PCB and microcontroller technology; this expertise is very recent and has not yet been applied to any current product.

The focus of the AE was in the development of a mixed signal ASIC to manage in the most efficient way the operation of a synchronous motor (including the start-up and synchronisation phase). The IC also makes the preprocessing and A/D conversion of the voltages on the stator windings and provides the PWM signal for the output triacs used as controlled current switches.

The introduction of Mixed Signal ASIC technology allows a strong reduction of the used material (copper of windings and iron of the core), by introducing a synchronous motor with permanent magnet rotor. This new solution should lead both to a reduction of the fabrication costs and to an increase of company European market share, to an improved electrical efficiency, to the elimination of the costs of the seal system together with the reduction of the dimensions and production costs.

The cost of the Application Experiment was 110 KEUR and its duration 15 months.

The expected payback period for the electronic components is two months and for the global investment is about two years from the start of production; return on investment, including Fuse and industrialisation cost, is about 250%, considering a projected life time of five years for the product.

Thanks to the Fuse funding the company could reach the above mentioned goals and, overall, it will be able to exploit the knowledge acquired in FPGA and ASIC technology for future projects.
