Hey I was wondering if anybody can help me out...
I have an controller which is able to supply max 1.25 amps and 0~8 volts(variable), however I need about 3amps to power a DC motor at required torque. I have used a transistor as a switch connected via a 9v battery to switch the motor on and off using the controller however then I loose speed control of the motor.
My question is this, how can I provide extra current via a 9volt battery to a my DC motor and still control the motor speed?
Thanx
