Tiny Pulse Motor by zanzal

Last crawled date: 4 years, 7 months ago

This is my fourth pulse motor and a culmination of refinements from previous versions. The last pulse motor I published was kind of slow and power hungry. This one is considerably better. I've ran it at 12000 RPM using an Arduino controller. I also spent some time tweaking a Bedini-style circuit which topped out at over 6700 RPM. The circuit is interesting too so I thought I'd share that along with the updated motor design. I was very happy that I could reduce the current draw to 7mA at 12.6V while maintaining 2500+ RPM. Very sweet. In all tests I only configured it for a single pole, but the stator has slots for a second pole if desired. Feel free to build one and comment. Feedback and observations are appreciated. Observe safety precautions when operating at high speeds.
