Riley Hurley's profile

Wiring and Controls

One of the most challenging aspects of this project was determining which electronic components to use. Ultimately, I decided on the Sevcon Gen 4 Size 6 motor controller, the Motenergy ME1507 motor, and a custom 3.9KWh battery. These components are expected to generate a substantial amount of power relative to the size of the motorcycle. As a result, the performance of the vehicle with the new electric powertrain is anticipated to exceed its prior performance by a significant margin.

One of the reasons I decided on the the Sevcon controller was because of its support for regenerative braking. Regen braking is a process that harnesses energy from decelerating. It captures and stores this energy in the battery for future use. To control the regenerative braking, I created a mechanism that uses a hydraulic brake handle and oil pressure sender. As the handle is squeezed, the oil pressure sender increases its output voltage. This voltage communicates with the controller and instructs it when and how much braking force to apply. This new handle also replaces the old clutch handle, combining classic feel with modern function.
