ECM motors have been around for a while and can be scrounged from heaters and air handlers being changed out.
These seem to be electronically commutated (magnets on the rotor) with built in drive electronics. I'm wondering if these have any good application to powering tools.
(1) They are efficient which may not matter too much with the hours of use they would actually get;
(2) They are made for direct drive blowers and there might be issues with the side loads that a belt would impose; and
(3) They seem to have a limited number of pre-selected speeds as programmed by the HVAC equipment maker. Any way to get around this and control them with a pot?
Thoughts?
