Triac DC motor speed control build schematics?

[DennisCNC]

Any one here build a motor speed controller that will run off 120V ac house power to run 90V dc motors using triacs? If yes, will you share your experiance and schematic.

Today I tried one of the Chinese router speed controllers for AC/DC motors with a fullware bridge rectifier and it runs a DC motor very nicely.

Thanks

You will need one that uses SCR's, not triacs if it is a DC motor.
It may not be worth building one when you can get Baldor or KB off ebay cheap.
I guess I read it too quick, I see you are using what is probably a Triac drive with bridge rectification.

Google "treadmill motor controller", plus there are usually controllers/motors on ebay as well.
