Today we present to your attention what is perhaps the most amazing of all existing electric motors! First of all, its exceptionally simple design is striking: two ball bearings are fixed on a common axis, their outer rings are fixed to supports, and power is supplied to these same supports — and that's all, not counting the flywheel, which ensures the smooth operation of this machine!
Apply a constant voltage of just over one volt to the motor, and a current of about 30 amps flows through the circuit, because the resistance of such a circuit is very low. Give the flywheel a gentle push, and the motor starts to accelerate, gradually picking up speed. If we push the flywheel in the other direction at the start, the motor will rotate in that direction, accelerating to the same frequency of 10 revolutions per second. This motor works perfectly underwater at even higher currents due to better cooling of the bearings, although they do rust quite quickly.
And here's another surprising fact: this electric motor was described back in 1961 in a patent application filed by Kosyrev, Rabko, and Velman from Novosibirsk, but since then, no theory has emerged that satisfactorily explains how it works! In an article by Soviet electrical engineers Polivanov, Netushil, and Tatarinova, published in the journal Elektrichestvo in 1973: www.booksite.ru/elektr/1973/1973_8.pdf a spark hypothesis was put forward, which linked the appearance of torque to the pressure of the plasma discharge occurring behind the bearing balls as they moved. However, at moderate currents, we did not see any spark discharge even in complete darkness.
The second, electromagnetic explanation links the appearance of torque to the interaction of currents flowing through the balls with the magnetic fields induced in them. But alas, the conclusions of this theory directly contradict the experiment. The third hypothesis is more plausible and explains the operation of the motor by the uneven thermal expansion of the balls. You can find out all the details in our video “Ball bearing electric motor”! Watch, think along with us, and don't forget to like!
