Hi guys, i want to control the speed of a 420W electric motor, or similar, which are used in electric scooters.

To cut the costs, i want to make my own speed control, and want to know if any one has done this before? please share your knowledge and experience.

Thank you.

Need more details! Like motor type, rating, stall current etc.

You'll spend more money than a commercial controller. Your title shows you're aware of the type of controller and the details. At 60A current, things melt pretty fast indeed.

This is not a student project....believe me!
