Zapytaj o produkt +


The experiments are carried out using machines of industrial manufacture. All the test machines are equipped with a special base for attachment to the Machine test system 0.3. The system allows the characteristics of the machines under test to be recorded. Power for the machines under test is provided via a variable transformer.


  • Protective measures and electrical safety
  • Setting up electrical machines and putting them into operation
  • Use of starting circuits
  • Assessment of electrical machine characteristics

Capacitor motors are rotating field machines with squirrel cage rotors which operate on single-phase AC. The rotating field is elliptical and is generated by a two-phase stator winding. The main winding of the stator is connected directly to the power supply, while the auxiliary winding, which is displaced with respect to the main winding, is supplied via a capacitor connected in series. In order to increase the starting torque, a starting capacitor is connected in parallel with the operational capacitor via a relay.

Basic Drive

  • Capacitor motors of the Basic Drive class are industrial machines which are supplied with the manufacturers' original terminal board. An illustration of the winding configuration has been deliberately omitted.
  • The safety sockets on the terminal board are safely accessible behind a plexiglass pane.
  • The winding terminals are labelled according to international standards.
  • Basic Drive machines are supplied with no temperature sensors and need to be protected from overloading by means of a motor protection circuit breaker. The experiments are therefore very similar to industrial practice.
  • Basic Drive machines are available exclusively in the 300 W rating class.

The complete equipment set is equally suitable for student experiments in laboratories with low voltage supplies (230 V AC) and for setting up on a mobile trolley for demonstration by teachers in a classroom. The procedures for the experiments are provided in a printed 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.


  • Connection and operation of capacitor machines with operational and starting capacitors plus current relay
  • Reversing direction of rotation
  • Measurement of efficiency and comparison with ratings on the rating plate
  • Recording of load characteristics
  • Investigation of the effect of the starting capacitor
  • Load characteristics
