“Engineers of Hitachi Magnetics Corp. of California have stated that a motor-generator run solely by magnets is feasible and logical but the politics of the matter make it impossible for them to pursue developing a magnet motor or any device that would compete with the energy cartels.”
Despite the above undated statement many have been producing magnet motors including our own Charles Watson with his Watson Magnet Motor, the WMM, which works somewhat differently than the following.
Kohei Minato’s Magnetic Motor
Kohei Minato and the Japan Magnetic Fan Company
“When we first got the call from an excited colleague that he’d just seen the most amazing invention — a magnetic motor that consumed almost no electricity — we were so skeptical that we declined an invitation to go see it. If the technology was so good, we thought, how come they didn’t have any customers yet?
“We forgot about the invitation and the company until several months later, when our friend called again. “OK,” he said. “They’ve just sold 40,000 units to a major convenience store chain. Now will you see it?” In Japan, no one pays for 40,000 convenience store cooling fans without being reasonably sure that they are going to work.
“Looking carefully at the rotor, we see that it has over 16 magnets embedded on a slant… She (Kohei’s daughter) then moves us to the next device, a weighty machine connected to a tiny battery. Apparently the load on the machine is a 35kg rotor, which could easily be used in a washing machine. After she flicks the switch, the huge rotor spins at over 1,500 rpms effortlessly and silently. Meters show the power in and power out. Finally, a power source of 16 watt or so is driving a device that should be drawing at least 200 to 300 watts.
Nobue explains to us that this and all the other devices only use electrical power for the two electromagnetic stators at either side of each rotor, which are used to kick the rotor past its lockup point then on to the next arc of magnets. Apparently the angle and spacing of the magnets is such that once the rotor is moving, repulsion between the stators and the rotor poles keeps the rotor moving smoothly in a counterclockwise direction. Either way, it’s impressive.
First, she shows us the cooling fan prototype that is being manufactured for a convenience store chain’s 14,000 outlets (3 fans per outlet). The unit looks almost identical to a Mitsubishi-manufactured fan unit next to it, which is the unit currently in wide use. In a test, the airflow from both units is about the same.
