Hi,
I need to run a PMDC motor rated at 6V. The stall current however is ~ 6 A. I need to run the motor using a 6V supply and draw <2A during stall. How can i achieve this ?
I need to limit the current through the motor to be <2A at stall condition.
One solution which I tried is as follows.
Using the output of a 5V Voltage regulator and pot , drive the gate of a n channel mosfet (sts12nh3ll). This circuit works for I<0.5A however I am unable to limit the current above this value.
May be I need to choose a lower rating N Channel mosfet. Will it work ?
what other options are available to limit the current of the motor (basically torque control is required).
