Why it matters

The significance of this zone.

The motor and controller decide how an EV feels and how far it goes. This zone puts a real motor, controller and battery on a bench with a live dashboard, so students can load, tune and stress them before anything goes on a vehicle.

Mistakes cost a test run, not a vehicle.

What you can do

Wire a battery, controller and motor and verify the setup

Run no-load, speed and torque tests

Watch phase current and temperature live

Check how the controller protects itself

Experiments

What students can run here.

System setup and communication

  • Powertrain wiring check: battery, controller and PMSM motor
  • Set up dashboard communication and verify live data
  • Validate hall sensors and position feedback

Motor control and performance

  • No-load run and smooth-rotation check
  • Speed control at different RPM set-points
  • Torque test with brake load
  • Acceleration and deceleration profiles

Thermal and electrical analysis

  • Phase current balance and waveforms
  • Motor temperature rise under sustained load
  • Controller heatsink and temperature limits
  • Battery voltage sag under load

Protection and safety

  • Over-current test: apply excess load and verify the controller cuts off

Curriculum

How students move through it.

Learners start on the LMS and the AI simulator, then run the experiments on the bench.

Indicative curriculum. The final module list is confirmed in your lab proposal.

Prerequisites

  • No prior powertrain experience is needed
  • Basic electrical knowledge helps
  • Complete the safety module before first power-up

How the LMS and simulator prepare learners

  1. Safety and orientationPowertrain safety and lab rules.
  2. Wiring and communicationConnect the system and bring up the dashboard.
  3. SensorsHall sensor and feedback checks.
  4. No-load and speed controlFirst runs and RPM set-points.
  5. Torque and accelerationBrake-load tests and ramp profiles.
  6. Thermal and phase currentAnalyse heat and current balance.
  7. ProtectionValidate controller cut-off.
  8. ReportingBuild a test report with efficiency analysis.
Outcomes

What learners can do afterwards.

Connect and verify a battery, controller and motor
Run torque-speed tests and read the results
Analyse efficiency and thermal behaviour
Troubleshoot voltage sag, thermal limits and unstable control
Who it helps

For institutions and for industry.

For institutions

Colleges and training institutes

  • A safe way to teach motor control hands-on
  • Students tune real controllers, not simulations only
  • Reports with efficiency and performance data
For industry

Startups, SMEs and OEM teams

  • Check controller and motor pairs on the bench
  • Find faults before they reach a vehicle
  • Keep logged data from every test run
  • Train service engineers on real hardware
