Test Bench For Electric Machines
The Test Bench For Electric Machines is
a multipurpose bench for the study and characterization of the
electrical machines using an automated test approach. 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.
- HMI (Human machine interface):
the heart of the laboratory. It performs the test automation and
provides the user interface to execute the experiments. The HMI
communicates with the other devices via serial port using the Modbus
protocol, reading electrical and mechanical data from instruments and
providing 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.
collect mechanical (speed, torque and temperature) as well as
electrical data, and can provide control signals to synchronize a
generator with the grid
