Description

The equipment facilitates the analysis of a sinus-commutated permanently excited synchronous machine (PMSM) with embedded magnets.

Objectives

  • Function as generator
  • Function as motor
  • Control of the direction of rotation
  • Speed control
  • Load behaviour
  • Step response

The learner analyses a permanently excited synchronous machine (PMSM) with embedded magnets as motor and generator. Measuring machine parameters, analysing machine characteristics with varying loads. Determining controller properties using the step response of the PMSM machine.

Highlights:

  • The measurements are performed with the converter controller  CASSY or with the machine test CASSY.
  • All measurement channels are potential-free and can therefore be used freely.
  • All measurements can be carried out with or without a computer.
  • In order to protect against overheating, the stator windings of the permanently excited synchronous machine are equipped with thermal detectors.
  • The permanently excited synchronous machine  has a didactic terminal board

All functions of the Converter Controller CASSY and the Machine Test CASSY 0.3 can be operated quickly and directly via the display, the rotary wheel and the buttons on the unit. All settings and measurement results can be saved on the unit and quickly called up again later or simply downloaded.

In addition, the Converter Controller CASSY and the Machine Test CASSY 0.3 is fully controllable in real time via RJ45 Ethernet, W-LAN and USB-C interfaces.

These interfaces can be used by the following software:

  • CASSY Lab 2 for drives and energy systems,
  • MATLAB® and LabVIEW ™
  • Lab Docs Editor Advanced

Several integrated servers are available in Converter Controller CASSY and the Machine Test CASSY 0.3 for the local media connection of at least four end devices simultaneously.

For more details, see product data 7735290 or 7735291 Converter Controller CASSY and the 7731900 or 7731901 Machine Test CASSY 0.3.

The equipment is equally suitable for pupil and student experiments in the laboratory with low voltage (DC, AC and three-phase current) and - with a mobile trainer - for teacher demonstrations in the classroom or lecture hall. The experiments are carried out according to the manual.

The target group is made up of commercial apprentices and students of electrical machine construction. The course offers experiments at an intermediate level and also allows for the necessary insight into machine behaviour for scientific interpretation at undergraduate level. The media connection makes the experiments suitable for demonstration in the classroom or a lecture hall.

In the following configurations there are further expanded experiments performed with the didactic frequency converter and a permanently excited or separately excited synchronous machine:

  • E2.6.1.1 Basics of commutation technology
  • E2.6.1.2 Block commutated synchronous machine
  • E2.6.1.3 Sinus-commutated permanently excited synchronous machine with surface magnets
  • E2.6.2.3 AC servo with industrial permanently excited synchronous machine
  • E2.6.2.4 AC servo with industrial separately excited synchronous machine

Topics

  • PMSM machine as generator
  • Control of the direction of rotation of the PMSM machine
  • Load behaviour of the PMSM machine
  • Step response and controller variables
