2kW Dyno

2kW Four-quadrant Dynamometer

Model 8540

The Four-Quadrant Dynamometer, Model 8540, is a new model which can be integrated to the Lab-Volt 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 Lab-Volt 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 HMI (Human-Machine Interface).  This interface enables the user to select the mode

of operation (Speed or Torque mode) and to set either the speed (rpm) and direction or the output torque (NAm or lbAft). The interface displays the main parameters of operation in real-time (Voltage, Current, Torque, Speed, 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 will stop if a problem occurs and the LCD will show the current alarm along with its description. The user is then able to reset the alarm and resume normal operation.

The Four-Quadrant Dynamometer comes with an electronic user guide which describes how to use the different functions of the module. The model can also be interfaced with a computer for monitoring and control. A demonstration application using National Instruments LabVIEW is included on same DVD-ROM as the electronic user guide. To use that application, the user must also order an optional communication cable, Model 88362.
