Not all electric motors during the work make rotary motion. Is among them and linear, carrying out reciprocating movement. It is possible to transform it to rotary by means of the krivoshipno-conrod mechanism, as in the internal combustion engine.
It is required to you
- - contactor;
- - plexiglas;
- - condenser, bulb, diode;
- - wires;
- - bolts with nuts;
- - otvertaka and wrench;
- - soldering iron;
- - drill;
- - 24-volt power supply.
Instruction
1. As a basis for the magnetic engine creating back and forth motion take the old contactor. Its coil has to be calculated on tension in 24 V of a direct current. Find couple of normally closed contacts at the device. So contacts which are closed at a deenergized winding are called and become isolated at operation of the relay. Include these contacts consistently with the coil.
2. Parallel to a winding attach in direct polarity the consecutive chain including the electrolytic condenser with a capacity about 2000 mkf and a bulb on 24 V, 90 ma (switching). It is the delay chain forcing the magnetic engine to work not too quickly. Without it the frequency of inclusions and switching off of the contactor would be defined only by lag effect of his mechanism.
3. Also parallel to a winding include, but this time not in a straight line, and in the return polarity the 1N4007 diode. It will protect it splashes in a self-induction not only contacts and elements of a vremyazadayushchy chain, but also the experimenter. But completely you should not rely on it as it can fail at any time.
4. Give on a collected design via the 0.5-ampere safety lock, observing polarity, the constant supply voltage equal to 24 V. If everything is collected correctly, the contactor has to begin to be involved and be released periodically. Cut off power the magnetic engine, and then paste to a solenoid rod a thin wooden core so that the rod was not pasted to the case.
5. Perpendicular to a core arrange the crankshaft bent from an office paper clip. Fix it in a P-shaped corner which place on the general-shaped basis with the contactor. Connect a core and the crankshaft among themselves the connecting rod manufactured also of an office paper clip. On both ends of the connecting rod there have to be eyelets, and, that from them which is turned to a core, fix on the last by the office paper clip inserted not up to the end. From one of the parties fit to the crankshaft a flywheel - a plastic disk with a diameter about 30 mm.
6. Having given food on the magnetic engine, at once untwist a flywheel. It will begin to rotate in that party in which you will push him. If it does not occur, experiment with various combinations of the sizes of elements of the device. Before each modification of a design cut off power it.
