Thread: Is the motor ok?

As an electrician, I can highly recommend throwing it in the bin and buying a new one.

So it can't be repaired? It was working fine when I had it attached to a power point.

Two good pieces of advice there, it would be wise to heed

Itis fairly obvious that you don't really have a clue. I doubt that anyone here is going to help you very much in your endeavour.

You are dealing with something that is potentially lethal, not just to you but also to whoever lives in the house that you are connected to and maybe your neighbours.

Stop what you are doing, step away from the motor , don't touch anything and call an electrician.

I have spent a huge amount of time adapting pulleys to this motor. Happy to throw the motor out but is that because of its appearance or how it's behaving now? Just trying to understand a bit about motors.

Definetly because of its appearance. It is an accident waiting to happen. Do your friends and family a favour and chuck it in the bin.

How unfriendly, ugly and evil looking do things have to be Tiger??

P*$s it off!!

Still like to know why it's so dangerous. If the red wire leading from the capacitor had not come loose, would it be ok?
I've done my time and money on this motor, what do I look for on the next one? Completely sealed? How do you assess the safety of a used motor?

Tiger, do yourself a favor, you are obviously clueless about electrical motors, throw it out, get a tested and working secound hand motor.

The money saved on repair bills, medical bills or worst case, funeral, will off set what you have spent on pulleys.

To further your education about motors take it to a motor rewinder. Let him have a look at it and then let him show you what the problems are. Yes you will have to pay for his time but I'm sure, like most sparkies, he will be glad to point out the problems and probably give you a couple of hints for future reference.
Its good to have a little bit of knowledge in all sorts of things. With a meagre amount of knowledge you will be able to see possible unsafe things around you

For the guys that are saying that I'm clueless and it's obviously a **** motor, how are you assessing that from the picture? The motor in the picture is currently connected to a light switch which can't be seen in the picture. Yes the red wire has become loose and the motor can't be used but if the red wire is reconnected correctly are there other faults?

That is where half the problem lies, we can only see a part of the motor and the fact that it is connected to a light switch which isn't designed to carry too much load doesn't help either.

Looking at the motor, you have live terminals all over it. You have said you have it hooked up to a light switch and you asked the question, can I rejoin the red wire. That tells me that you don't have a clue and are asking for trouble. To me, who see's these dangerous situations all the time where untrained people trying to save a few bucks put there lives at risk, I am trying to do you a favour. A little motor like that is pretty cheap, and getting pulleys lathed out is pretty cheap too. Feel free to join on the red wire though, I'm just advising you of what I'd do.

Mate,
a few people have taken the time to warn you off with a few hints. Your enthusiasm for learning more is admirable. Please read a bit about single phase motor design and connections on the net, then read a bit about Australian wiring rules, learn something about voltage, amps, watts, ohms, earth connections of household power supplies, earth leakage and fault currents, insulation properties of various materials etc.
None of this can be learnt by trial and error by a single person. Lots of people have died in the process of developing the knowledge and rules we have today! Don't reinvent the wheel and be one of the latter. Please. Do your learning by reading and asking questions (when you have enough knowledge to understand the answers).

The fact that this motor has a completely open frame means it is designed to be built into some equipment WITHOUT user access. The fact that you were able to photograph it and refer to pulleys you adapted to it means it is now user accessible - and a lethal risk to ANYONE going into you workshop.

This is addation to everything the other respondents have said already. Yowie who is a sparky has gone out of his way more than most sparkies would. Heed his advice.
By the way, if you don;t want to throw the motor out, disconnect it completely, take it apart and see how it is constructed. After you have reas something about motor design, it may become a teaching aid for you to see how one particular type of motor is actually made. I'm saying that because the winding and wiring is very difficult to see and follow in fully enclosed fan cooled motors (like you should be using in a workshop). But please don;t see this as any kiind of encouragement to reconnect it again some time in the future! It is NOT! Once you figured out and had a good look at the wiring inside and the coil construction, strting circuit, the likely centrifugal started mechanism etc - then THROW IT OUT.

Stay safe, Tiger!
