Its unique radial flux motor concept uses a dual-rotor configuration to produce copious amounts of torque from a particularly compact, lightweight, cost-efficient package. Well beyond some specs ...

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 ...

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 ...

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.

But making something that produces motion—a motor—has proved much trickier ... the tiny rotors out of several components. Each rotor consists of two paddles attached to a shaft that lies ...
