I am wanting install an Elektromec Fan motor into my cooker hood. It has six wires coming out :brown/blue/white/red/orange/black. I need to know what each of these wires does?(in plain simple English!). I believe it has three speeds and would fit in a BoschDKE995EGB Cooker hood or a Neff. The model no is EGBR1136.1CL.F 6.3uf’

I don’t my paying providing the information resolves my problem!

Sci.Electronics.Repair FAQ: Notes on the Troubleshooting and Repair of Small Household Appliances and Power Tools

Note section 14.12

There will likely be a common, high, low, medium
and two leads for a capacitor

Two of the colors will likely have zero ohms. One will go to the external capacitor.

The trouble will be, identifying the other side of the cap and the speed windings. But the cap winding should be identifyable with the resistance matrix.

If you can post that, then we ought to be able to determine the color code. Using a lamp in series will prevent damage when doing the final test.

Hi
Thank you for your reply. There is no visible capacitor and I wondered if the was a starter winding built in. I have had it running but only slowly and it developes a cooking smell! (which is not bacon! ) To fit both Neff & Bosch I would have thought it could be standard but nobody seems to know. I am unable to test as I write but will do so at the first opportunity

The 6.3 uf is the value of a capacitor. A 6UF cap is located here: CeilingFanParts.com - Switchco Products - 2-Wire Capacitors

Capacitors are always external. They need to be rated for an AC voltage.

This may help. It may not: Ceiling Fand wiring Diagrams

Tuff finding info on this, appear to be 3 speed. Can you get the control? At the end of the model number it says "6.3uF" which usually means 6.3 micro farads(The Value of the Capacitor)The capacitor(if it does use one) needs to be rated for the voltage or higher.
Just a wild guess, and wouldn't try yet, could be something like blue and brown to capacitor, white to neutral, and red, orange and black for the speeds? It really bites that some common information is not more easily available.

I checked out the fan diagrams link provide by KISS, The reverse switch they show is the
L,1,2,3 type switch. Usually on fans they use a double pole double throw switch which swaps 2 wires.

Here are Wiring Readings

Meter set to 200 ohms

+ on Brown - on Blue = Flash reading only
+ on Brown - on Black = 135.2
+ on Brown - on Red = 21.9
+ on Brown - on orange =172.4
+ on Brown - White =193.8

Blue was split to feed two points

I understand motors to a degree, was always curious how to determine where to apply voltage to a motor to operate, if 2 speed, and for reverse, and for dual or multiple voltage,
Motor guys could say out of their head, The post he provided may answer my questions.
I think he or other motor person needs these resistance measurments:
Brown to: Blue, white, red, orange, and black.
Blue to: White, red, orange, and black.
White to: Red, orange, and black
Red to Orange than Black. Then
Resistance between Orange and Black.
ALL readings are important. If I get a chance, or no one answers, I will decypher.
I bet KISS could get it, But needs all above resistance readings.

I just noticed you mentioned a "Flash Reading". With resistance you have a resistance, a short, or open (infinity). If it was an Analog meter on a Capacitor, and you touched leads needle would kick over the slowly drift back. A digital meter may give a "flash reading"(eratic?)you describe?

Strat:

The guy with the diagrams has a cryptic style. He states: Reversing switch truth table (all types described here, yellow switches)

1 (Forward):L to 1 , 2 to 3
2 (Reverse):L to 3 , 2 to 1

Which swaps wires. Just not obvious.

Colinn:
I need the matrix. Polarity doesn't matter.

Colors on x axis, Colors on y axis, Resistances between the colors.
If two colors;

------wht blk
blk 10 0
what 0 10

Just fill in the complete table.

Here is the matrix
Brown Blue Black Red Orange White
Brown Flash 134.3 21.7 171.5 192.6
Blue Flash 94.9 Flash 58.3 36.6
Black 135.2 94.9 113 37.5 59
Red 21.9 Flash 113 150 171
Orange 172.4 58.5 37.6 150 22.4
White 193.8 36.6 59.1 171.5 22.4

Hope it is OK
Cheers
Colin

Brown Blue Black Red Orange White
Brown Flash 134.3 21.7 171.5 192.6

Second attempt

Colin:

Something is wrong.
White-White must be zero
Red to Red must be zero
Orange to Orange must be zero
etc.

And it has to be consistent.

What does flash mean? Are you using auto-range?

What happens when you just short the leads of the meter together?

Well, actually zero doesn't exist, but it has to be a small number like <0.6 or so.

Something may be wrong with your leads, the connections or the meter. You can hold the wires to the probes with your fingers. The resistance of the body won't matter.

I loaded the table into Excel.

didyou get my poor effort of a matrix?

Kiss, I think he was measuring white, red and orange to each of the other wires.
Colin, The reason a color was dropped after each color was because the resistance test has been done already. Once brown was measured for resistance between the others, then when you get to blue, you don't have to measure to brown, it should be the same as
Brown to blue.
What kind of Meter(Analog or digital?) Explain Flash.

Kiss, I would have expected some open readings, unless motor was controlled by taps?

Brown Blue Black Red Orange White
Brown Flash 134.3 21.7 171.5 192.6
Blue Flash 0 94.9 Flash 58.3 36.6
Black 135.2 94.9 0 113 37.5 59
Red 21.9 Flash 113 0 150 171
Orange 172.4 58.5 37.6 150 0 22.4
White 193.8 36.6 59.1 171.5 22.4 0



Using digital meter set at 200ohns

Flash means a figure briefly appears and meter goes back to 1

Touching the probes together reads 01.0

Let's go with:

White is common
Orange Hi
Blue Medium
Black Low


Capacitor between Red and Brown

Put a light bulb in series with the motor and use the low speed. Try something like 25 watt. If there are any ratings on the nameplate like HP or watts, post that and I might change the light bulb wattage.

How am I wiring the capacitor in? I don't know! Sorry So I am sayng from the mains is what?

The capacitor has two leads and is non-polorized.
Connect one end to Red and the other lead to Brown.

To make the motor run at low speed:
Cap the orange wire and the blue wire. Meaning they go nowhere.

Connect Hot (Black) to a 25 W lamp and the other end of the lamp to Black (motor) for testing.

Connect Neutral (White) to White (motor)

The only light bulb I can lay my hands on is 100w.
The motor is rated at 200w
In the UK neutral is usually blue?
