    Electrical Turning a single phase motor into a generator

    Scrap the washing machiene and replace it with a front loading washing machiene motor. Mine had a 3 phase perminant magner motor that will run as a 3 phase AC generator and put out a fair amount of current. A 3 phase bridge transformes it to DC

    What is the Difference Between 12:00 AM and 12:00 PM?

    Summary:: what do 12:00 AM and 12:00 PM really mean. How do you say the time at at noon. is noon 12:00 AM or 12:00 PM? 12:00 AM means 12 hours before meridian or before noon so 12:00 AM should mean 12 hours before noon or midnight. 12:00 PM means 12 hours past meridian or 12 hours...

    Auto/Motor Get a 1945 Harley running again

    There was one more funny thing about the Chief. It had only 2 cams. One for intake and exhaust on one cylinder and one for intake and exhaust on the second cylinder. As each cam rotated its first raised the intake then later it operated the exhaust. How about the haley

    Electrical A speed limiter for a Universal Motor in an old Lionel Train

    I suggest a variac which is a 0 to 130 volt variable AC transformer. If you connect it to a 12 or 15 VAC transformer you will have a close approximation of what Lionel used in their transformers. They come in different wattage ratings. A small one is not too expensive and will probably...

    Extracting an electric grounding spike

    I would grab the rod with a pair of vice grips. Then use a car sissors jack with a board underneith to pull it out. Hold the vice grips parallel to the ground.

    Auto/Motor Get a 1945 Harley running again

    Back in 1959 or so i paid 35$ for an 1948 Indial chief. It was very sinilar with foot clutch and 3 speeds on a hand shift. I took apart the flywheels and had to get a machienist to re assemble them. They are 2 cast iron wheels with a tapered pin mounted way off center to profide trhe...

    Capacitance of a Sphere: A Quick Calculation Method

    Could anyone tell me the capacitance of a one food diameter metal sphere. I know that this is a one terminal component but it still should have a capacitance. If a charge of Q is small and a 6 inch radius is drawn about the point then that 6 inch radius ( 12 in diameter ) should have a...

    B A flip of the Earth on its axis

    The ball has a 1/4 inch hole drilled through and filled with lead. Then a 1/8 inch hole is drilled at right angles to the other hole and filled with lead. To answer your question the ball needs to be spun about the 1/8 inch hole. Also on the subject of table tennis balls if you...

    B A flip of the Earth on its axis

    "Instability means that small perturbations can cause a flip. " Where does the instability come from? "The ellipsoid explanation shows an isolated system, where angular momentum and energy are conserved." I agree "But in reality you have some external torques, and energy dissipation"...

    B A flip of the Earth on its axis

    I wonder how the spinning wing nut knows how long to to wait between flips. What determines the timing.
