    No problem. Just thought it worth mentioning so that people don't buy the cheapest thing they think may work. :)

    The light dimmers I was talking about are DC PWM, not phase controlled AC ones. They are only a couple of dollars (eBay example), but as I said they are not suitable for motors. I wasn't saying that the failure when using them was the motor. On the contrary it's the switching FET in the dimmer that goes shorted, resulting in full speed no matter the knob position. Hope that clarifies. :)

    One thing to note when using PWM controllers on motors. Make sure you get one that's specified suitable for motors. The cheaper ones only meant for dimming lights are easily damaged by motors. Been there, done that.
