The Four-Quadrant Dynamometer is a model which can be integrated to the 2 kW Electromechanical Training System, Model 8013. This model can act as a prime mover or as a dynamometer, depending on user preference, and it can easily be coupled to any motor and generator from the 2 kW product line.

The Four-Quadrant Dynamometer consists of a squirrel-cage induction motor with an encoder feedback. The motor is driven by a closed-loop vector drive which is coupled to a touch-screen Human-Machine Interface (HMI). This interface enables the user to select the mode of operation (speed or torque) and to set either the speed (r/min) and direction or the output torque (N·m or lb·ft) of the machine. The interface displays the main parameters of operation in real-time (voltage, current, torque, speed, and frequency).

Electrical connections between the vector drive and the motor are made through jumpers on the front panel. This makes the separation of both components simple and allows the motor or the vector drive to be used independently in other experimentations. The vector drive is well protected against abuse.

The vector drive stops if a problem occurs, with the LCD showing the current alarm along with its description. The user is then able to reset the alarm and resume normal operation. The model can also be interfaced with a computer for monitoring and control.
