This uses magnets on a rotor, which interact with a reed switch to time pulses of electricity to coils which drive the motor. [Tom] wound the coils and built the motor from scratch using 3D ...

As the motor turns, a permanent magnet passes by the reed switch and it makes the circuit. All of the electromagnets, which are wound in series, fire and kick the rotor forwards. Then the reed ...

All BEVs today use radial-flux motors. In a radial-flux motor, a doughnut-shaped wound-copper stator sits around a central rotor often embedded with a series of permanent magnets. They are ...
