router speed controler

[cueshark]

can i use a router speed controler to vary the current going into a torodial transformer? if that will not work, can i use it either before or after the capcitor when it is dc to vary the voltage? i need 95 volts max.thanks greg

Not the best idea and it will not work in all the senario's you mention. Also the technology varies on router controls from PWM to phase angle control.
I would look at removing/adding turns to the Toroid first.
Do you want to increase or decrease the secondary?

i have a 90volt dc motor.. theps output is 92 volts i was thinkingthat maybe i could use the router controller to slow the motot down by using it instead of buying a motor controller rated for 110 volts @ 15amps. i as just wondering, maybe i could use something i already had instead of buying a controller. thanks for sharing your knowlege. greg

If it is the AC speed control that is used on universal motors, you may be able to use it in the AC secondary between the secondary and the bridge.
Is it a Universal motor or a permanent magnet field type?

i do not know! it is a lesson treadmill motor. how do you tell what is what? greg
