Compact EV Drivetrain Layout Design

About the project

I am converting a small city car to full electric power and need the complete motor-to-wheel package laid out in SolidWorks. The core focus is the motor and drivetrain, so every model, mount and shaft you create should revolve around a single high-torque brushless DC motor. Scope • Position the motor, gearbox (if required) and final drive within a very tight engine bay while preserving existing suspension pick-up points. • Design custom motor mounts, couplings and adaptor plates that can be fabricated from aluminium or mild steel plate. • Specify reduction ratios and gear arrangement that deliver strong launch torque yet allow 110 km/h cruise without over-revving the motor. • Route half-shafts and CV joints, checking angles and plunge travel against current suspension geometry. • Balance mass distribution and keep unsprung weight changes to a minimum. • Verify clearances with dynamic envelopes; include simple Motion or FEA checks where interference or stress is likely. Deliverables (native SolidWorks 2020 or newer) 1. Fully-constrained 3D assembly of motor, mounts, gearbox/reducer, differential and shafts. 2. Detailed part drawings ready for laser-cutting or CNC machining. 3. Bill of materials with material specs and off-the-shelf components listed by part number. 4. Short report summarising design decisions, torque path calculations and any simulation results. Acceptance criteria • All parts fit within the provided engine-bay envelope (STEP file will be supplied after award). • Drivetrain withstands peak stall torque of 450 Nm with a safety factor of 2.0. • No component clashes during ±50 mm suspension travel and ±30° steering lock. I will be on hand to supply the original ICE sub-frame model and answer dimension queries quickly so the work can move forward without delay.
