Super-Pid question

[Drools]

I have salvaged a Brushed DC motor from a small broken electric snow thrower. It is rated at 120V 60HZ 6.5A. The motor is running through a full wave bridge rectifier I was wondering if I could use it as a spindle motor and use the Super-PID on the AC side.

Thanks for the help.

You would need to find out if it is a DC P.M. motor or a universal series wound motor, if the latter, then it may be possible to run it on a SuperPID, if it is a DC shunt P.M. field then you would need something like the KB or Baldor DC SCR controllers.

Thanks Al.
The snow thrower did not have any sort of speed control just an off/on control. The AC is rectified and it looks like there is a temp controled circuit breaker inline on the AC side. Looking inside the motor, I can see what looks to be large magnets on the casing.
I already have a Porter Cable router and I'm thinking on getting the S-PID for it. How would the DC SCR controllers compare to the S-PID? The S-PID is closed loop and I'm thinking it would hold a constant speed better than the SCR controller.
Thanks for the help.

The DC SCR's have current detection feedback for rpm but are not as precise as the SuperPID would be, although they do have facility for a DC tach if you cared to fit one.
The RPM of this motor is probably not going to approach that of a Universal motor either.

Again Al thanks!!
I was actually looking at this one for a low speed solution <5k for doing Plastic/Ali/Brass.
hmmm maybe something to look into.
Always a great help Al.
