Hi, so me and two of my friends decided, that we should build a electric racer.
we decided we should use two 500W DC motors, and i, being the circuit guy, started looking into, well the circuits. However, i have never done anything with motors, but i do know, that what ill need is an H-Bridge.
The specs of the motor:
I though of making an H-Bridge, consisting of 2 P-channel, and 2 N-channel, but then thought, that that would be a hell of a lot of power to run over two mosfets.
other than that, i dont really know how to choose a mosfet. How much should the rated amps be above what i need? Could i run several mosfets paralell to split the load out and reduce RdsON, or should i go with power BJT?
The H-Bridge would be controlled by an arduino, the output of the pins on that would be 5v 40 mA (though i wouldn't run the pins at more than 30 mA to be safe)
so yeah, thanks a lot for taking a look
