Step 1: Solar Motor Components :
1. coil iron – less (bobbin)
2. two mini solar panels
3. fidget spinner with iron insertions
4. step up booster ( optional component)
5. 3 neodymium magnet discs
6. reed switch
Step 2: Operations :
1.fix the neodymium disc magnets on the fidget spinner disposed N-N-N
2. fix the reed switch on the coil iron – less
3.connect the solar panels through wires to thestep up booster (optional component) or direct to the coil iron-less -reed switch (1 wire to the coil, 1 wire to the reed switch)
4.place the flywheel ( fidget spinner with iron insertions + 3 neodymium magnet )under the coil
5. place the solar panels in a lighted area.
Step 3: About :
A pulsed motor uses short pulses of current to drive the motor, making it spin. The part of the motor that spins is called the rotor. Acting as a flywheel, and has multiple permanent magnets. These magnets are usually extremely strong (neodymium magnets) and can be arranged in a variety of different configurations.
The stator is the stationary part of the motor that surrounds the rotor. It holds one or more electrical coils. They are positioned so that the magnets line up with the coils/coil, during part of the rotation. The coils are energized when they are exactly lined up with the permanent magnets in the rotor.When electrical coils are energized with a short pulse of current, they produce a repulsive force. How it works ? The pulse motor is one of the simplest motors and works very well under low voltages. When magnet gets close to the reed switch, the two contacts inside the glass tube get magnetized and touch each other. The coil iron – less pushes magnet away with the rotor. When the rotor spins away, the reed switch demagnetizes and the contacts move back to their original position (the coil is disabled). The rotor continues to spin due to inertia until the next magnet gets in working range of the reed switch. It becomes magnetized again and its contacts connect together (refering to reed switch).
