Very nice motor

I used this Dewalt to replace a motor in a Linac. It fitted nicely and was a few 100 grams lighter, plus 2x the rpm:)

A few down points to this motor is that the gear on the shaft was very hard to remove (but as it is meant for a drill, what can you expect). Also the plastic top area looks to me a little fragile and I will have to watch it for damage.

But for the specs and performance well worth the price!!!!

the motor worked well, but a magnet within the motor got loose easily and i had to take the motor apart and glue the magnet back on with lock tight to put it back together.
