A discarded universal motor donated its rotor and bearings. The windings were stripped off the assembly leaving nothing but the commutator. 1kΩ SMD resistors were soldered across adjacent ...

Organic chemists have now produced a light driven rotary motor in which the rotary movement is locked to that of a secondary naphthalene rotor. For a motor to power machinery, the local motion has ...

giving the rotor a little boost. The difference here is that rather than low-friction sapphire bearings, this motor uses zero-friction magnetic levitation using pyrolyzed graphite discs.
