Motor Mojo & PiCADS — Motor
Pi-CADS Motor is a browser-based motor simulation platform for engineers, EV teams, and students. It evolved from MotorMojo, an early proof-of-concept tool, into a more complete platform with guided inputs, simulation states, admin views, and light/dark UI systems.
I designed both MotorMojo and Pi-CADS Motor, including the core product flows, simulation screens, admin module, and landing pages for both products.
01 — Overview
From proof of concept to simulation platform
MotorMojo started as a simple browser-based tool for motor simulation. It helped validate the idea that engineers and students could run motor design workflows without expensive desktop CAE software.
Pi-CADS Motor expanded that idea into a more professional platform — supporting multiple motor topologies, complex input flows, simulation states, admin controls, output views, and a stronger design system.
02 — Problem
Making engineering-heavy simulation usable in the browser
Motor simulation requires many technical inputs across vehicle specs, motor geometry, materials, winding data, and simulation parameters.
The UX challenge was to make the workflow feel guided without removing the technical depth engineers needed.

Complexity needs structure
This project taught me that complex products do not become usable by hiding complexity. They become usable when the complexity is structured clearly.
Designing Pi-CADS also taught me to work closely with engineers, understand unfamiliar technical terms, and turn dense product logic into workflows that users can actually move through.
