We are developping the simulator of a car, and  for the steering the
feeling must be as real as posible. The  wheel must return to the neutral
position if the car is moving  and the wheel is free, and the torque and
speed of the return must be a function of the speed of the car and the
other variables. Also would be posible control the resistance to the
movement applying more or less voltage to the electrical motor.

To achieve all this functions, we are thinking in a DC motor, controlled
by a DC motor controler with RS 232C interface to connect to the
PC that control the simulation.

Any other ideas?, problem with this implementation?. In particular,
I am not very expert in electrical motors, but it seems to me that problems
could arise if motor try to return the wheel to neutral positi�n
and the driver try to move it in the oposite direction, I think that the
back emf change of sign, working the motor as a generator and produce some
kind of shortcircuit with the supply o the controler(except the  winding
resistance). Please some aclarations and ideas would be
very useful.

Thanks in advance

Juanjo
