Sunnyvale, CA | you have the open collector resistor correct (your question 1)
your question 2 -
the DC resistance of the motor is about 2 ohms, so the maximum current with around 12 volts is about 6 amps. (I=E/R - remember Ohm's Law) the motor will have maximum torque and use the maximum current when turning slowly and maximum speed with no torque load - like all DC motors. the motor is bullet proof with 12 volts at all PWM duty cycles from 0 to 100%. your PWM controllers with a 40A limit probably has a low resistance, so you won't get much voltage drop across them limiting the performance of the motor. | |
