aquaclear powerheads have flow control.

 

[manderx]

nope

Works with any universal AC/DC brush type motor

powerheads are brushless.

Yup, those will not work with 99.99% of the motors out there.

They work with drills, and routers because drills and routers are typcially universal motors . You powerheads and pumps are typically shaded pole synchronous motors....

the electronics within these type of speed controls are not based on reostats, rather voltage regulators and need a commutator to control the motor as the above post suggest.

I guess I should have added, that to control the speed of a synchro motor... you need to vary the frequency or use PWM... Much more expensive and much more complicated.
