A Design for Three Phase Electronic Controller for Electric Motor Cycle Equivalent to 100-125 Cc Engine Power with Regenerative Braking System

Abstract

Technology always have the potential to disruptive the society, especially electronics since this technology follows Moore Laws. Electric vehicle is predicted to change how individuals are going to do their daily commute. Electric motor cycle is an answer to eco-friendly transportation, economical in the operation and will be more affordable in the future for the people. One of the main component for this vehicle is the 3 phase motor controller. Three phase electric motor has an advantage of being light weight, low cost and more compact compare with dc motors with a comparable power. The design is featuring a regenerative braking system which brings back the mechanical energy back to the system on braking time hence a significant advantage to increase energy efficiency, since a major power lost is happening during braking on conventional vehicle. The design on purpose is using 100-125 cc equivalent of gasoline engine since this engine has the most market in Indonesia. Which is about 10 to 15 KW 3 phase AC motor.
