The Motor Test Bench with Rope Brake Load by Decibels Lab is designed to provide hands-on understanding of electric motor behaviour under varying load conditions. The setup enables learners, researchers, and engineers to perform practical experiments on the identification of motor base speed, stall torque, speed-torque characteristics, Motor & controller efficiency analysis.

The setup enables students, researchers, and engineers to practically study:

• Motor speed-torque characteristics
• Constant torque & field weakening regions
• Motor efficiency mapping
• Stall behaviour
• Electrical-to-mechanical power conversion
• Real-time telemetry and data acquisition

Learning outcomes using this platform, learners can:

• Understand EV traction motor behaviour
• Perform torque-speed analysis
• Identify motor base speed
• Study field weakening operation
• Generate efficiency maps
• Analyse power conversion
• Study motor thermal behaviour
• Understand motor loading principles
• Perform real-time telemetry analysis
• Develop engineering calculation workflows

The platform integrates:

• PMSM motor drive system
• Rope brake dynamometer
• Load-cell-based torque measurement
• DAQ and visualisation software
• Real-time logging & analysis tools

The setup includes a complete DAQ & GUI software for operating the motor, logging data, exporting Excel workbooks, and post-processing analysis.
