Servo-machine test bench
The servo-machine test bench provides a complete testing system for examining the performance of a range of electrical machines.
An inverter-fed DC motor operating as variable speed drive. Students will learn closed-loop control concepts, and can configure and optimise the drive controller.
Power multimeter and transformer unit
Power multimeter: Simultaneous, measurement of voltage, current, active, apparent and reactive power as well as the power factor.
The transformer unit in this experiment allows students to investigate single, three-phase and autotransformers. A range of experiments can be performed, these include connection and operation of the transformer in various configurations, measurement and calculation of the transformation ratio and no-load and short-circuit experiments which allow extraction of an equivalent circuit.
DC Multi-circuit, compound wound machine, 0.3 KW
In this experiment students can operate and characterise a DC motor in a shunt wound, series wound or separately excited configurations.
Machine characteristics and determination of dynamic and static operating points
The program allows the recording of machine characteristics and determination of dynamic and static operating points. It can emulate different loads such as a flywheel, pump, fan, lifting drive, compressor, winding gear or an arbitrarily configurable time-dependent load for which the parameters can be individually configured.
Properties of an induction motor
In this experiment students can operate and characterise an induction motor. Additional topics covered include star and delta configurations, reactive power compensation and measurement of phase and line-to-line quantities.
Three-phase power converter with block/sine commutation and space vector modulation
The following circuits can be configured: A single or four quadrant controller, AC inverter, frequency converter drive or three-phase inverter or a variable speed DC drive.
Three-phase synchronous machine and synchronisation unit
Investigating wind power generation
In this experiment, students investigate the design and operation of modern wind power stations with double-fed induction generators. The effect of wind force and the mechanical design of wind power stations can be emulated in using the servo machine.
Equipment storage racks
The electrical engineering lab uses modular Lucas Nülle equipment that can be configured into a range of experiments.
