why do you think there would be a problem? if it is connected correctly & given the right voltage it should work fine. it looks to be a foreign made motor.see it is made in india. wouldn't expect the same performance as an american motor , but i could be wrong.

The "foreign made" part is what im worried about. I dont know how well it will work up to its ratings or how long it will last.

I am going to try to use them on a drill press, so i dont know how well it will work for that. I will have to live up to its 1/3 hp rating.

Ok i will trust you on that one...

$40 is very questionable, but it is just $40, so why not...

Many motors including many US companies outsource motors. What motor line besides Baldor do you think are actually built in the US?
Brook Crompton has a good name in the industry.

Why would you be running it wye connected? It very well could be a nine lead motor.
In fact, unless its nine leads, its not a true dual voltage motor.
Price looks good. Whats the application?

I will be using some for multiple applications, one on a drill press(if it works well), one on a small hose acceleration pump, and one more just for testing.

12 lead motors are dual voltage.



At that price and if that is a name brand motor I would suspect it is a Chinese knock off. They like to copy things and the have one tiny misspelling to remove liability.

How much does it matter if it fails? You didn't say what the application was.

I would take it apart and look around before I used a motor that cheap.

Oh, I missed it. I wouldn't use it without first taking it apart and checking out what they went so cheap on. All of that stuff sounds like hobby related projects not industry related projects.

The pump is going to be the most important. I will be building It soon. It
will have to be running almost all the time, its for a water flow accelerator for a pump system, so it must be running almost all the time under load. Starting and stopping will be computerized by a programmed vfd.

If it's really important, why are you using a cheap and questionable motor?

If it's a critical asset you don't go cheap. I would never put a questionable motor into operation doing something where a failure would either cost money, cause damage, or cost production time.

I don't just see the cost of the motor I see the cost of replacing it with another motor, the cost of the lost production, the cost of damage caused by the failure of the motor, and the cost of replacing other components that possibly would go out due to a domino effect of the above mentioned failure.

I mean, it's whatever you want to do but since I do industrial maintenance wherever critical assets are concerned I spend the money for reliability instead of trying to cut corners.
