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).
For use on double 'C' core, wound with 1,100 turns of 22 swg copper wire with a resistance of about 6 ohms and inductance of about 15 henries, size 100 x 60 x 55 mm approx.
To distinguish between the conductors and insulators.
Kit contains five strips of different material (wood, acrylic, copper brass and aluminium), one lamp and one 9 V battery mounted on plastic base.
Wound on rectangular bobbin, for use with 220 – 240 V AC mains with detachable mains connector with moulded plug, A 4 mm socket is provided for earthing.
With this simple electric motor model students can investigate the relationship between voltage supplied to rotor and polarity / position of magnets.
On applying 6V DC to 4mm sockets, the rotor will begin to rotate across its vertical axis.
Generates both AC and DC.
When the two brushes of the generator are put in the two ends of the commutator, the output is an AC.
When the brushes are put in the middle of the commutator, the output is a DC.
Includes Instructions.
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.
