PMSM EduLab Explorer Kit


Accelerate Innovation in Motor Control

Motor Control

Purpose

The EduLab Explorer Kit is an all-in-one hardware-and-software solution for hands-on teaching of PMSM (Permanent Magnet Synchronous Motor) control principles in undergraduate or graduate labs. No extra installations are required beyond MATLAB/Simulink and a USB-connected testbench, allowing immediate live demonstrations with an intuitive GUI—no coding required.

It also includes a ready-to-use Simulink model for software-based simulations, letting students validate control algorithms before deploying on real hardware.

Key Features

  • Demonstrate PMSM principles in a lab setting
  • Enhance teaching with real-world demonstrations
  • Easy-to-use simulation tool with no extra installation
  • Immediate live demonstrations without coding
Key Features
Simulink Model

Core Components

  • Dual low-voltage PMSM modules in a portable form factor
  • Basic inverter drive with open-loop and closed-loop modes
  • Transparent motor casing for mechanical visibility
  • Real-time data acquisition via FreeMASTER
  • Instructor station with guided experiment software
  • Emergency stop and safety interlocks

Lab Setup & Workflow

  1. Unpack & Connect: Mount PMSM on its stand, connect inverter to DC supply (8–18V), hook sensor lines to ECU via USB.
  2. Launch EduLab Model: Open EduLab_Explorer.slx in Simulink; select “Hardware” variant.
  3. Initialize FreeMaster: Run provided script to start FreeMaster; auto-detect ECU and load parameter set.
  4. Run Live Demo: Adjust SpeedCmd slider; switch between Open-Loop and Closed-Loop modes.
  5. Data Logging & Analysis: Capture time-stamped logs of speed, torque, and currents to MATLAB.

Experiments: Beginner → Advanced

  1. Experiment 1: Open-Loop Testing – Characterize PMSM behavior without feedback; log speed, torque, and current vs voltage.
  2. Experiment 2: Closed-Loop Testing – Compare PI speed-control vs open-loop; step changes, load disturbances, voltage variation.

  1. Experiment 3: Control Tuning & Strategy Comparison
  2. Experiment 4: Four-Quadrant Operation
  3. Experiment 5: High-Speed Field Weakening

  1. Experiment 6: Automated Motor Drive Testing
  2. Experiment 7: Efficiency Mapping & MTPA

Learning Outcomes

  • Fundamental PMSM behavior under open-loop conditions
  • Closed-loop PI control understanding
  • Controller tuning & performance evaluation
  • Four-quadrant operation & power flow analysis
  • Field-weakening techniques
  • Automation & scripting with MATLAB/FreeMaster
  • Efficiency mapping & MTPA optimization
