Hey guys, here i am going to show that, how to make a high speed dc motor car with 9v battery at home. simple school science project ideas for exhibition.my. Step 1: get make a power board and control board. you are going to need a control board and etched power board. the power board needs to be at least 3 ounce copper. ebay is a good place to look for heavy cheap copper clad pcb.
This mind blowing build is by an electrical engineer who decided to design a 45kw motor (that’s 60hp). that’s not a typo. design and build a 45kw motor! he has a video series on the design. Controlling the speed of a dc motor is essential for many diy electronics projects, from robotics to model cars. in this tutorial, we will create a dc motor speed controller using the 75n75 mosfet and a few other common components. this project is perfect for hobbyists and enthusiasts looking to gain hands on experience in electronics.
