AC PWM Controller for DW660?

[regressedEE]

Different sources suggest that AC PWM control is possible/is unfeasible. What do you think about something like this for controlling the speed on our Dewalts: AC 50V-220v 10A 13 KHz PWM Motor Speed Control Controller.

free bump - I'm interested in this as well. Would this allow speed to be controlled by Mach3?

No, that would allow the speed to be controlled by the black knob.

Looks like it would more suited to control an AC fan and you couldn't do much at slower speeds?

This might be a better option if you don't mind shelling out $40 and soldering.

Unfortunately it gets more expensive from there if you want decent torque at lower RPMs. Variacs. Super PID.

I use a router speed control box with a black knob on it. The speed control is ok and does change the speed of the DW660. However, it does seem (I have not measured this so I don't know), that there is less power/torque at lower RPM. However, this is better than no speed control at all.

In reality I want to have a PID controller connected to a RPM sensor, so that the spindle speed can be controlled reliably. I know superPID is out there, but I really want to go the open source route with this.

Generally speaking, the woodworking press and the router manufacturers recommend that you don't use an external aftermarket speed controller for a router. The motor isn't designed for an external control.

However, that is not to say that it won't work, just that it may shorten the life of your motor.
