I have a small batch of ~1.5mm square cylinder re magnets. If coils are air wound, about how may turns, and volts, current could I plan for? Framing in aluminum or plastic, Y or D wiring... I haven't thought of any other use for them yet. |

Love to see it in a small old-timer. |

Motors generally need to have an EVEN number of poles. The magnets are arranged N - S - N - S etc., so it leaves a discontinuity of you have two N N in a row. Jon |

Jon --- End quote --- Yes, but I think the OP is talking about a solenoid motor, where each cylinder head on a radial engine is replaced by a solenoid. The crank/hub can be a direct copy of a radial that way. OP - Do you have enough magnets to do a Double Wasp, do you think? It's only 18 cyls. ;D There are a few folks on Youtube that have made various solenoid motors, I'm pretty sure I've seen at least one radial, but most seem to be boxers/horizontally opposed for simplicity. |

If so, I want to hear it. My dad was with a B-29 squadron in WWII. |
