[QUOTE="Tathradj, post: 226198, member: 2436"] With a two speed motor you have 3 brush's. Two are placed directly opposite each other and that is your high speed. For low speed, The third brush which is off set comes into play. With the later model design, A pulse width modulator is used. Much cheaper and easier to produce and more expensive to buy. :rolleyes: The latter is the most efficient and effective way of speed controlling a DC motor. Making sure you use heavy transistors with a good heat sink. . Direct drive wiper motors are a good choice providing that they do not have much weight on them and to do that you use gearing and don't stall them. With a one to two gear you half your speed and almost double your torque. [/QUOTE]
