I want to build a circuit to control the rotation speed of a slot car motor. The motor (0-10V/2A) will be supplied by a 0-30V/3A DC power supply.
The rotation speed will be controlled by the analog output (0-10V/5mA) of a National Instruments data acquisition board.
To sum up, I need a circuit to vary the voltage of the motor based on the change of daq AO voltage.
Any ideas would be awesome.
