Emotron AB develops, manufactures and markets high-technology
products which drive and supervise machines and processes driven by electric
motors. The overall market consists of manufacturing and service industries
where the products from Emotron are protecting machinery and processes,
cutting energy consumption and reducing the wear and tear on equipment
components. Emotron has about 150 employees and a turnover in 1999 of
180 MSEK (about 21 MEUR). The industrial sector for Emotron products is:
IP, Industrial process control system.
The main users of FU´s are within the pump and fan industries, together
with conveyers and other material handling equipment. Today Emotron is
protecting all these applications with the El-Fi monitor when directly
driven. However, the present product range can, by technical reason, not
work with the above applications when driven by an frequency inverter.
With the new technology Emotron can also penetrate this, frequency inverter
The AE involves design of a general measurement module for load monitors.
A load monitor uses an induction motor itself as a sensor to supervise
the driven load and protect it from destructive over- or under-loading
by limiting the load torque. Load monitors are used in applications where
electric motors drive for example pumps, fans and screw conveyors. The
load monitors are designed using through-hole or surface mount standard
components on printed circuit boards.
The main objective of the AE is to implement a more advanced measurement
principle at a lower production cost for the load monitors. This will
make existing models more competitive but will also make it possible to
design new load monitor models that will expand the market into areas
where load monitors have not been used before. The analogue ASIC implements
a true three phase measurement principle that also enables use together
with frequency inverters. Both these advantages will be achieved at a
lower production cost than the current less advanced models.
An analogue, array based ASIC has been developed in co-operation with
Svenska Grindmatriser AB. The ASIC realises a general motor load measurement
module. The AE duration was 17 months and the cost 105 kEUR.
The payback period for the development of the updated load monitors is
8. The Return of Investment is 429% considering a product lifetime of
three years. Emotron has further acquired knowledge about partitioning
and designing an analogue ASIC and in evaluating an analogue design with

|You can also benefit from microelectronics
Analogue ASIC technology provided Emotron AB with the means of improving
its products and enhancing its market position. You can also achieve significant
benefits by acquiring the right microelectronics technology and utilising
it in your product or manufacturing process. You can get help from FUSE
to realise this.
FUSE is a technology transfer programme, funded by the European Commission to stimulate the wider use of microelectronics technologies by European enterprises to increase their competitiveness and enhance their economic growth. The demonstrator described here is one of many examples in the public FUSE portfolio covering the whole spectrum of microelectronics technologies and spanning a wide range of applications and industry sectors.
FUSE provides you with:
- Best practice in acquiring specific microelectronics technologies and conducting full development projects through the FUSE portfolio of real life demonstrator documents.
- Local training and expert support to plan your innovation realistically and help you conduct your project successfully.
