Due to certain circumstances I need to run my brushed DC motor in reverse (positive to black wire, negative to red wire).
What I noticed is that when set up this way running at no load requires 1.5A. Running it forwards, as I assume is supposed to be run, requires 0.9A and judging by the difference in pitch I'd say is running quite slower than in reverse.
I did a quick search and found out that this is some hardware setting on the motor which increases torque in one direction at the expense of torque in the other direction. Since I'm not all into that I wouldn't want to disassemble the motor and could live with difference in torque but I'm having trouble figuring out which direction is set up with the higher torque.
AFAIK higher current means higher torque, so in my case my motor will have higher torque in the reverse direction, which is even better for me because that's how I need to run it. However the motor was sold to me originally as an e-scooter motor, which doesn't make much sense, why would they increase the torque in reverse on such a motor which will barely ever be run that way given it's original purpose?
