The input power is 1.9 watts and the output rotational force is 7Nm at 10 radians per second or 7watts. The electro magnet uses 19.6 volts @ 1.2 amps for 28 ms or .658 watts per pulse. It spins at 95.4 rpm and makes 1.59 rev per sec. There are 2 magnets on the rotor, so the EM fires 2 times per rotation. 2 X 1.5 rps = 3 pulses per sec. Or a total input of 1.974 watts. I decided to upload this video because of all the comments about the first video being edited. Here is another movie where I walk all around the machine to show that video is NOT edited in anyway. The wire from the electromagnet is connected to a power supply. The mechanical rotational force of the rotor creates more watts per second than the electromagnet consumes. The device on top is a digital torque sensor to measure the Nm force under a load. The device under the table is a digital encoder to read the position of the rotor to fire the electromagnet at the right time.
