quite unusual, experimental electric motor design modeled on the so-called generator. American woman. Characteristics:
- plywood disc rotor (diameter 70 mm) from the sunken in polyester resin with three coils of 200 zw. 0.5 mm DNE,
- stator consists of two plates of sheet iron with a thickness of 1 mm, in which four magnets are attached apron,
- 3.sekcyjny typical commutator, brush with a brass plaque of 0.5 mm
- bearings - brass socket radio systems .
- Location magnets (determined experimentally) on one plate alternately N-S, magnets, two plates, "looking at each other," the same poles (repel). magnets on one plate are placed centrally on the coils, the other on the edge of the blade. After placing the engine (before gluing magnets in their places) you can quite easily manipulate them experimentally determining the best location - hold the stator plate quite a bit.
- Instead of the typical commutator is shown in this structure can be usefully applied structurally simpler commutator flat with laminate for printed circuit boards.
- method of execution and dumping the coils in resin is described in detail in posts on the construction of "American."
- engine design is very simple and easy to implement in terms of the average home workshop. The engine can be successfully used to drive different models, especially the flying and driving.
- engine features high torque (rotor diameter!) And very high turnover: starts from 1.5 V at 5V reaches very high speed and it is observed a tendency to rozbiegania up. "
- modernization Directions: larger diameter-larger coil - more power. The next increment will achieve maximum efficiency approaching magnets to the blade and optimizing the position increasing the number of magnets and coils (and the commutator section.)
NOTE:
rotor brushes in the diagram should be rotated 90 degrees (parallel to the magnets)!
