90 Degree Rotors – semi levitated
Finally built a replication of Lidmotor’s 90 degree magnetic gearing. Normally I run a vertical rotor to interact with another vertical rotor, but this way intrigued.
My magnets are a lot smaller, but the ‘range’ for the interaction is still quite decent.
Speaker magnets form the levitating sections of the horizontal rotor.
Strong glue is used in most small speakers to hold things together. That glue can be dissolved in a strong solvent. Then a strong pair of pliers can be used to take the speaker cone metalwork off and the magnet is released by prising it gently from the central piece of metal that the speaker coil normally sits on. I haven’t heard of such a method being used before and hope it’s of some use as a tip…the main thing is that a hammer doesn’t have to be used !
The solar pieces can deliver up to 1.5V and charge the supercap quite readily.
As the charge decreases and the rotor slows, the circuit uses less power. A run of 1/2hr is possible, though the 90 degrees rotor will lose sync well before then.
