This motor-generator set gives students an insight into the physical and technical relationships on which electric motors, generators and transformers are based.
The modular system allows to set up different function models without tools: Various DC motors Series and shunt motor Synchronous motor DC generator and alternator Transformer.
This set allows the performance of 10 student experiments about the following topics:
Magnetic field of a coil
Conversion of electrical energy into kinetic energy
Commutator
Direct current motor
Synchronous motor
Series and shunt-wound motors
Electromagnetic induction
The electrical generator
Engine-generator
Transformer
The motor consists of a two pole armature mounted between the ends of two bar magnets.
The armature has a two section commutator and a pair of slip-rings on its shaft and is so constructed that the wire cannot slip off the iron core.
The upper bearing and brushes for the commutator are mounted on a strong upright.
Separate brushes are provided for the commutator and for slip rings and each are connected to a terminal.
The magnets are held in position by thumb screws.
Students can explore how a simple electric motor works by doing a series of investigations.
This St. Louis motor can be adjusted so students can study the effect of voltage and position of the brushes on the commutator.
The motor consists of a two pole DC armature. The brush holder, with two heavy binding post terminals, can be rotated for experiments.
The permanent bar magnets, supported by clamps, can be adjusted to the desired location.
This apparatus requires 4 D cell batteries with holder (not included) or a power supply and two connecting leads (not included).
