Frequently Asked Questions

How does the 24-magnet array work with just one solenoid?
With 24 magnets spaced evenly on the rotor disc, one solenoid magnet and one reed switch are enough to keep the disc spinning. The close spacing of the magnets means the reed switch triggers reliably without needing multiple coils. Related terms: 24 magnet array pulse motor.
Why did Papa Bale reduce from many solenoids to just one?
Fewer solenoids means fewer resources used and more room on the breadboard for other experiments. It also simplifies the circuit and reduces electromagnetic interference between coils. Related terms: single solenoid 24 magnet rotor.
Does the 24-magnet array spin faster than other configurations?
Papa Bale believes that under the correct circumstances, this configuration will go the fastest — since all 24 magnets are N25 strength and spaced consistently, the timing is precise and the rotor can accelerate well. Related terms: N25 magnet array speed test.
What voltage is the 24 magnet array pulse motor running at?
The motor was tested from 12.3 volts up to 20 volts. At higher voltages it picks up speed quickly — though it takes a while since the disc is heavier with 24 magnets on it. Related terms: reed switch pulse motor timing.
What is the next step for this motor design?
The goal is to align two discs — one with 24 magnets and one with 12 — and use the same reed switch to drive both solenoid magnets simultaneously, creating a counter-rotating or dual-disc setup. Related terms: modular pulse motor build.
