Our CLASSIC 16 bits Digital Signal Processor DSP-card is custom designed to control the complex and demanding starting cycle and power control of our FFPE or STELZER MOTOR , a truly unique Free Floating Piston Engine. The "brute" math capacity of the DSP makes it possible to do that task with a very limited number of components / circuit boards.
allowes "in flight" piston-position forecasting, needed for optimum ignition and injection timing and avoiding engine breakdown. In 1991 the availability of high speed DSP's lead to a breakthrough. The FFPE finally evolved as an alternative for conventional stationary engines, outside engineering laboratories.
If you are just interested in alternative engines and/or energy perhaps you should browse our FFPE page now.
We saw and took the opportunity to develop a new breed of CNC-controls with DSP-processor.
The Analog Devices DSP has become the main engine in all of MACs' numerical controls, replacing over 4000 IC's in NC's of the mid eighties being necessary for high speed and high resolution/precision on 3- to 7-axes machines.
