Yes tks for that , and I think I may have one kicking about somewere , So can I discount the resister way then ! .Use a light dimmer, these are usually Universal type motors in hoovers, and respond well to dimmers.
Just thinking with the light dimmer , would it take the current ie 1200Kw motor ! .Use a light dimmer, these are usually Universal type motors in hoovers, and respond well to dimmers.
That sounds expensive ! .You need to get the power tool version, either that or DIY version if the former is not available where you are.
Throttling the output, lowers the motor current but heating may occur due to reduced air flow.

No, the motor will be fine.I thought about that , but would it not overheat the motor ! .

Was thinking of building a thyrister controller ! .You could look at the wall mount ceiling fan variety of controllers and check the No. of the Triac used and beef it up, if needed.

Unlikely, but you could build in a slipstream to keep a small airflow over the motor even if the main flow is cutoff. The motor will act like a vacuum cleaner motor when you block airflow. It’ll speed up a little because there’s a reduced load.I thought about that , but would it not overheat the motor ! .

I think if you divert the airflow instead restricting it, the motor won't overheat. Might be very loud.I thought about that , but would it not overheat the motor ! .

There are several for ~ $2.00 each on ebay and Ali express etc,

I have used just a 10 amp diode to slow some power tools. It just gets a half wave. I think I got that idea from a Makita sander.
Interesting , tks
Thanks just what I am wanting , trouble is if they are from China I may not get it untill quite a few weeks time , I could really do with making one , have lots of electronic parts , would anyone have a schematic of this type of controler ! .There are several for ~ $2.00 each on ebay and Ali express etc,
