Design and Analysis of Hub Dynamo for Electric Vehicle

Aim of the paper to design the variable speed permanent magnet based hub generator. This dynamo is suitable for supplying power from ebike motion and use to driving hub motor. The hub dynamo have a hub axle, a hub housing rotatable mounted around the hub axel with bearing. The power generating mechanism with coil fitted to hub axel that has connected to output wires. In this hub dynamo, the magnet rotates with the speed of ebike; here we get power output from dynamo. We use that power for battery charging of ebike with proper charging circuitry. Hence we can improve the performance of ebike. In this paper, we are going introduce the power output of our own designed hub dynamo.
