Hello people!
I am new to this forum but i couldn't find any specific information easily. Let me describe you what i want to do.
I have a wheel gaming controller for a pc, which provides feedback information to the wheel through 2 simple DC motors that turn a larger gear which is 1:1 with the wheel.
The motors voltage is controlled by a board which simply takes usb information from games, and translates it to -24 to +24VDC as output for the motors.
Here is the board controlling the motors, in red the 2 mosfets (9977GM and 4951GM), 3 diodes (P6KE27CA) and motor connections (parallel):
The motors on the circuit are in parallel. As you add motors you increase the performance of the wheel, all aspects (torque wise). I modded the wheel and added 2 more motors, and i only have tested the 3 of them because i am afraid of the mosfer amplifiers capacity.
It has 2 amps, the 9977GM for the positive supply and the 4951GM for the negative. They are rated to 60V - 3A approximately. The motors are 24V - 0,7A each and by default it uses 2. I also replaced the stock 24V power supply with a factory grade 24V - 5A one.
As far as specs go, the fets and surrounding diodes seem to handle 4 motors but i don't feel good pushing them to their limits. I added a large heatsing to the mosfets also.
My question before i risk connecting the 4 motors... Is there a simple circuit i can make that replicates the boards output but can provide more amperage? (board output -> circuit that gives same voltage but more amps -> motors)
I know i can swap the mosfets with better ones, if someone can provide specific info it will also be great,
