Duncan Morrison Posted January 27, 2004 Report Share Posted January 27, 2004 Hello peopleI have got the task of building a show engine for the new Rolls-Royce Phantom. The engine is motorised and is going to be powered with a 220v single phase 50Hz supply. The motor will have a rating of about 3kW. I would like to vary the speed of the motor using the cars throttle pedal. The pedal uses a hall sensor (i think this is the same as a variable resistor but with no physical electrical contact. The pedal is supplied with 5v and has an output of between 750mv and 4500mv. Can anybody help me design a circuit to control this motor?

MP Posted January 28, 2004 Report Share Posted January 28, 2004 What you might be looking at is a Throttle Position Sensor (TPS). This is used to tell the on-board computer the position of the pedal in order to make other decisions such as what gear to change in the auto transmission or to richen the fuel mixture. I am not familiar with this particular engine but I do have overall experience with automotive computers in general. I have found that the best way to control the throttle on these engines without causing other errors is to connect a cruise control servo to the throttle link at the carb or fuel injection and control the servo with electrical pulses.MP Quote Link to comment Share on other sites More sharing options...
Staigen Posted January 28, 2004 Report Share Posted January 28, 2004 I dont think thats what Mr Morrison requested, but i also think we need moore input from Mr Morrison. What type of motor driving the engine for example. Some motors is not very suitable for variable rpm. Excuse me if i am wrong.//Staigen Quote Link to comment Share on other sites More sharing options...
MP Posted January 29, 2004 Report Share Posted January 29, 2004 I agree. We are just shooting in the dark without more information. What model is the motor? Any links on the web where we might get more information?MP Quote Link to comment Share on other sites More sharing options...
hotwaterwizard Posted January 29, 2004 Report Share Posted January 29, 2004 Take a look at this link!http://www.redhouse.force9.co.uk/dexterspage/electr~1.htm Quote Link to comment Share on other sites More sharing options...
Staigen Posted January 30, 2004 Report Share Posted January 30, 2004 Hey John, dont you think this is a little too simple, how to interface this to the hall sensor for example? And how much current do BTW10-400 stand. I did a little search for data on it, but i did not find any.//Staigen Quote Link to comment Share on other sites More sharing options...
