Hi, I'm new to this forum and I had read a few threads in this forum. Also, I'm quite new to building electronic circuits eventhough I'm studying electronics -.-. My college doesn't give us many projects.
I'm trying to build a motor driver/controller and I read that PWM is a good way to control the speed of motors. I saw some circuit diagrams online but I don't really understand most of them. There are some simple circuits and some complicated ones and I'm not sure which to use.
I'm currently building a 3-wheel human transporter for my project and I'm using a 12V 40A lead acid battery. I've used a controller from a golf trolley and it worked fine but I figured since it's my project, it's better for me to build one. I saw a person doing something similar using this circuit:

a suggestion said that to parallel another 1 or 2 mosfets. I'm not sure whether it works and judging by the components, I'm not sure whether the other components, other than the mosfet, can withstand the power when the motor draws a high current to push a heavy load.
Please help me out here, thanks
