Series 7 strand coils motor – fast
2x 7 strand multi-strand coils in series, on a simple pulse motor setup, producing a very fast speed for the 3.3V volt input. 8x neodymium magnets in a North/South alternating configuration. C3200 100mA NPN transistor ensures no more than 100mA Collector current output. Datasheet here: www.datasheetcatalog.org Hall sensor is a U18 Milliamp reading is across a 1ohm resistor There are no magnets on the backs of the coils. The wall adapter is a 3V to 12V M-800/A-27252, with a FWBR and 16V 3300uF smoothing capacitor (to give a cleaner power source).
