The start winding cut out electronically after start up near rated frequency. More suitable for a fan than a drill press though. | |

Feb 7, 2016 at 2:22 | comment | added | John D | As a side note it is possible to vector control an AC induction motor for variable speed with nearly full torque down to 0 RPM. It's not a $100 solution either though..... | |
