13 Top 18 Gauge Magnet Wire Galleries - Last time i left off with kitmotter 0002 suffering from melty-hub syndrome; at some stage in take a look at riding, the stator had gotten so hot as to melt its sintered nylon hub partially, inflicting it to lose grip at the shaft and shear my twine insulation off, inflicting a short. It was clean that i would should replace the hub with some thing extra long lasting and excessive-temperature.
The out of doors tolerances were accurate, so the stator slipped on properly. I used ultra-thin ca glue to preserve it – the stuff wicks into the thin and porous mdf gap thoroughly. A better temperature solution could be coating each stator bore and hub in epoxy, but this became quicker.
I elected to laser this one in-residence for quick consequences. I got a bit off at the tolerances, so this is going to end up a touch tight, but with a view to be constant inside the layout files earlier than i release them.
As i mentioned before, the winding on kitmotter 0002 become type of bullshit – like kitmotter 0001, i made it fast without any goal of it absolutely generating torque. There’s a huge amount of open area nevertheless in the ones slots. 30 turns of my chibikart hex-28 gauge produced a reasonable torque per amp, but it got here at the value of excessive resistance – i.E. Not that many amps to be had. For vehicles of the identical size, a better resistance motor has a tendency to warmth up greater and run slower simply due to the i*r penalty of no-load cutting-edge draw coursing via it. It additionally gained’t produce as a lot stall torque due to the fact the r limits the stall contemporary.
I ordered three extra reels of magnet wire for my “hobbykinging rig” that i made for winding the chibikart automobiles. 9 28 gauge strands in parallel are equal to a roughly “18.Five gauge” winding in terms of “round mils” of copper. It must lessen my resistance by means of a 3rd, putting me extra inside the .28 ohms variety. I am hoping.
