I have 2 of these 12v motors and a 12v battery http://www.enigmaindustries.com/Motors/Bosch_EV_Warrior.htm
I would like to know what the best solution for controlling this motor with an Arduino Uno would be. Does the motor controller need to have a maximum current of 100A?
I though of a 100A transistor connected to the pwm pin of arduino, and then, control the motor with pwm.
Is voltage regulator better than pwm?
