Frequently Asked Questions

What adjustments improved the pulse motor's performance?
Key adjustments included raising the solenoid magnet slightly (about half a millimeter from the array), swapping blue wires to eliminate confusion, and moving reed switches to wood to avoid magnetic interference from steel poles. Related terms: pulse motor minor adjustments.
Why did Papa Bale move the reed switch to a wood stick?
Steel poles create magnetic interference that affects reed switch performance. Mounting the reed switch on a wood stick eliminates this interference and allows the switch to trigger more reliably. Related terms: magnet height half millimeter.
How much voltage and amperage does the optimized motor draw?
The motor runs smoothly at 7 volts with only 1 microamp of current draw — extremely efficient. At 7.75 volts it spins vigorously. Papa Bale prefers keeping the amp draw low to avoid overheating and component stress. Related terms: reed switch wood mount.
What is Papa Bale's final goal for this motor?
The ultimate goal is a double spiral magnetic sculpture that runs all the way up a central pole — spinning discs that are a pound to a pound and a half each. This requires a motor that can drive significant weight over time. Related terms: microamp current draw motor.
Why does the motor sometimes need to be 'backed into' to start?
The reed switch is delicate and sometimes operates at half voltage, causing dim indicator lights. Back-feeding or spinning the rotor fast in the right direction helps the reed switch find its timing and get the motor started. Related terms: pulse motor troubleshooting tips.
