I promise this is my last motor wiring question...

[astro_al]

Right, one day I'll stop asking stupid questions about motors & wiring, but until then:

Finally forked out on a new fan and speed controller. Single phase.
Motor has a starting capacitor (2 wires, obviously).
Motor has 4 wires (including earth).
Speed control has regular E, N, L inputs - ok so far - and 4 outputs - E, Z, U, U/Z.

I assume this means I use the '3 wire control' scheme on the speed controller?

I attach the label on the motor housing and the wiring diagram for the speed controller.

My question is, how do brown / blue & black on the motor relate to U, Z & U/Z outputs on the controller?

Where do I wire in the capacitor? (OK, should be obvious from the diagram once I know which wire is which).

What do the lines between L & N and between N and (blacked out circle) on the fan housing mean?

Ta for any help. I've finally forked out real money, so I know these are designed to go together.

Does the motor already have a capacitor?

Looks like:

blue - U
black - U/Z
Brown - Z through capacitor.

 

[astro_al]

Yes, it already has one clipped to it, but the wires are separate to those listed for the motor.

Ta, Al.

single phase i take it? if its a three phase motor then the Cap goes between two windings so Live to U1 N to V1 and the cap between U1 and W1

 

[astro_al]

Single

 

[madkayaker]

is it a single motor as well?

 

[astro_al]

What?

 

[madkayaker]

bit more awake than i was last night so make more seance now.


U on the speed controller is Live to the motor
U/Z is Neutral
And Z is through a capacitor to Brown

Ok, thanks, works great. Initially ran the wrong way, so I swapped the Z and U.

Runs great now, if anyone needs a speed controlled fan, check out ACI:

Thanks for the help.
