1. [Amps] slow down circuits for 240v blower (score: 1): Author: "Neil Carr G0JHC" <g0jhc@blueyonder.co.uk>; Date: Tue, 18 Nov 2003 06:47:06 -0000; I'm wanting to fit a front panel control on my latest amp project which will allow me to reduce the speed (and noise) of my EBM blower, (G2E-140) especially during long periods in receive.

I have used that in the past, did not slow down the blower as much as you would suspect, but did the job! 73 - Mark, AA6DX; /archives//html/Amps/2003-11/msg00249.html (8,521 bytes)

It can also cancel the series XL of the motor winding. Not so good. What you want is enough Z to limit the current and reduce torque.

(Hons) G8TIC" <mike.tubby@thorcom.co.uk>; Date: Wed, 19 Nov 2003 13:47:22 -0000; The trick that I use is a "motor run" capacitor in series - typical values are 1-15uF 440VAC rated. You can use a single cap or more than one if you want more than two speeds and switch across them.; /archives//html/Amps/2003-11/msg00267.html (10,603 bytes)
