Motor wiring advice

Motor wiring advice

Motor wiring advice

(OP)
I'm needing to wire this motor (see attachment) and need to be sure of what I'm doing. Can someone please advise? Thanks in advance.

I'm thinking that black and brown are my two hot leads that connect to the breaker and that blue and green/yellow both go to the neutral/ground bar. Please correct me if I am wrong.

RE: Motor wiring advice

230V 60Hz, assuming you are in North America, does not need a Neutral connection. So black and brown for your two hot lines, green to ground.

RE: Motor wiring advice

(OP)
jraef thank you. Yes, I am in the US. So should the blue just be capped? Would it harm the motor to connect the blue along with green/yellow to the ground/neutral? Also, I'm assuming that reversing the position of black and brown will reverse the rotation. Is that correct?

RE: Motor wiring advice

Sorry, Jeff, gotta disagree. Given that diagram, black should never leave the vicinity of the motor, blue and brown are the two hots and green/yellow goes to the ground (not neutral) bar. I believe that reversing the motor would mean reversing the whole black circuit, capacitor and winding, to change the angular relationship between the two winding, but maybe it's something else; see if the manufacturer has a website with instructions.

RE: Motor wiring advice

Blue and Brown are hot.
Capacitor between Black and Brown.
Non reversing.

RE: Motor wiring advice

That’s the problem with using the referenced images; I had to write the response without being able to see it any more.... Short term memory failed me.

RE: Motor wiring advice

Thanks for the support Keith.
I had to scroll up to the image several times Jeff.
Same problem.
What were we just talking about? grin

RE: Motor wiring advice

Dear Mr Jam es

1. According to the wiring diagram the wire colour complied with the IEC colour code.
I think this motor may be manufactured in Europe which complied with the IEC standards
but ended up in US.
In the IEC world, colour code is as following: Line (brown), Neutral (blue), earth (green/yellow).

2. For your case, connect (brown) to the line, (blue) to the neutral and (green/yellow)
to the earth. The (black) wire and C=capacitor shown dotted should had been factory
pre-wired.
The (black) wire and C are shown dotted indicating that the C is an [external component] that comes with the motor but is [not] in side the [motor winding housing]. The C usually appears as a[black block] or a [cylindrical metallic tank] attached on the casing of the motor.

RE: Motor wiring advice

Assuming 60Hz means North America, there's no neutral involved.

RE: Motor wiring advice

(OP)
Che Kuan Yau Given that this motor is 60Hz do you really believe that it was produced in Europe?

RE: Motor wiring advice

(OP)
There is no capacitor mounted on the exterior. It is a sealed aluminum casing and I was operating on the assumption that there was an internal capacitor, since the capacitor details are listed on the label. I guess the existence of the black lead may indicate otherwise?

RE: Motor wiring advice

Dear Mr Jam es
1. My assumption that the motor could be manufactured in Europe is based on the wire colour
is as per IEC standards. IEC wiring colour code is applicable for 60Hz devices.
2. The colour (Brown), (Blue) and (green/yellow) is not in accordance with NEC, by law in US.
3. What you are concerned is only three wires i.e. (Brown), (Blue) and (green/yellow). The (black)
wire and C are part of the factory pre-wired inside the "sealed aluminum casing".
4. Connect (Brown) and (Blue) to a 230V 60Hz supply; (green/yellow) to the frame of the
"sealed aluminum casing".

RE: Motor wiring advice

I would guess that it is a Chinese motor. RPM on the label (which is a sticker and not a nameplate) is misspelled as RMP. The capacitor is not inside the motor if the black wire is available outside the case. Even the typeface is what is commonly used on Chinese made motors.

RE: Motor wiring advice

(OP)
Thanks to everyone who has chimed in on this.

I'm attaching another photo showing the wire bundle that includes the black lead and extends more than 40" away from the casing. It's looking like I need to acquire a capacitor that meets the specs on the label and mount it away from the motor, presumably along with a switch.

Can I get a consensus from as many as are willing, please? Along with any other advice that anyone deems appropriate.

Again, thank you all!

RE: Motor wiring advice

The diagram indicates a run capacitor and not a switched start capacitor, if that is what you mean.

RE: Motor wiring advice

(OP)
Compositepro - I was referring to the 50uf/450V spec. My mention of a switch was in reference to a main switch to turn the motor on /off.

I was just beginning to search for a capacitor and was confronted with the start vs. run options. What indicates that it should be a run capacitor?
(I'm obviously a novice and greatly appreciate your input)

Also, when I add this capacitor to the circuit, what connects to the other pole? I'm guessing it connects to the same hot as the brown wire. Please correct me if I'm wrong.

RE: Motor wiring advice

Dear Mr Jam es
1. I agreed with Mr Compositepro's learned advice.
2. The C should be a [run] type capacitor. Attention: there should be [no] switch in the
capacitor circuit; as you are already aware of.
3. The (Black) wire should be wired to one end of the (external) [run] type capacitor.
The other end of the capacitor connects to the (Brown) wire as shown in the diagram.
Note: [Run] type capacitors on the market are not marked with + and - polarity. Therefore,
no issue with the (Black) wire connecting to the capacitor terminal is reversed.
4. Please [test !] to confirm that the (green/yellow) wire is factory pre-wired inside, which is connected to the [frame] of the sealed aluminum casing.
5. The external (green/yellow) wire is to be connected to the [Ground] of the power source.
