Also, there are at least three types of electric brakes: two types of

regenerative: the stuff you are talking about is proly an "internal"
type,

thru winding switching. There is also regenerative braking back into the

"grid", or thru high-power resistors.

Or, you just power the motor backwards! Which would require pinky-sized

wiring....

Don't forget DC injection for stopping motors..
It is not regenerative, and it is not running it backwards..


Yes, that's been mentioned before. I think that's how VFDs stop the
motor as well.

newsreader - everything ends up double-spaced. Perhaps a configuration
problem? JMG
