The system is composed of the following main sections:
• Prime mover: A squirrel cage three-phase asynchronous machine controlled by an inverter in four quadrant operation providing the mechanical power and torque necessary for the characterization of the machine under study.
• Data acquisition software for electric machines: performs the test automation and provides the user interface to execute the experiments. The SW developed in LabVIEW communicates with the acquisition devices via serial port using the Modbus protocol, reading electrical and mechanical data from instruments.
• HMI gateway: provides the commands to the prime mover, so it can be used as drive, load or a speed and torque control to put the machine under test in a specific working condition or to simulate different load profiles such as fan, lift, etc.
• Instruments: collect mechanical (speed, torque and temperature) as well as electrical data (AC and DC, Voltage, current and Power).
