problems with motor-generator kitReviewed By: bahram fotouhi In project 6 of this kit, was really disappointing. My ten-year old son and I encountered two major problems in building the generator.
The first was the instruction given to bend the core, after the magnetic wire was wound onto it, was not sufficiently well thought of. After we carefully wound six rounds of the magnetic wire onto the core, during bending of the core to the desired U shape the magnetic wire inadvertently broke on the outside of the bend as it stretched. The location of the break was impossible to locate and fix as there were six turns of winding on top of each other. After experiencing this on three different trials, we finally decided not to wind the wire in the location of the bend so as not to break the winding. Which worked as we measured the resistance of the final winding to be almost a few Ohms.
The second problem was that, after putting everything together and adjusting the gap between the armature magnets and the tips of the single core to 1 mm, we found out that the armature had to turn very fast in order to light up the LED with one wire-wrapped core. In fact, I had to spin the armature with my electric drill before seeing any noticeable light form the LED.
