European 3 phase motor connections
The motor was specified to be or volts. Lately, I have had to hook several European - German motors. Run simulations on both your local machine or in the cloud.
If two wires are not on the same coil, you will measure an open circuit. If you let me have the type and serial number I may be able to find out when it was made and who the original customer was via my Brook Crompton agent. Promoting, selling, recruiting, coursework and thesis posting is forbidden. One thing is for sure, the motor we have is definitely not the one that we were supposed to have purchased.

Motor Connection Diagrams
Delta will have the three corner points of the high voltage connection connected internally and one common lead brought out. The only way that I know of to operate at a different voltage with a six lead motor is to make the low voltage a delta connection and the high voltage a wye connection at the motor. Most stepper motors come with four, six, or eight wires. The Adafruit motor shield can run two stepper motors using four wires for each so we're going to connect white and red and orange and blue to stepper motor port to.
Star will have one star point made internally and inaccesible. That would fit with your description as this being connected for the lower voltage. Did you make this project? How to use an old six wire stepper motor and control it with an Arduino. Best to find a source close to you.

This is the way it is wired now for high voltage. Posting Guidelines Promoting, selling, recruiting, highlands coursework and thesis posting is forbidden. It's easy to join and it's free. By joining you are opting in to receive e-mail.
Here are the resistances is that I measured. It is in the low voltage connection pattern already, but it is rated for V. If you don't have one, it's worth buying one as you can get one for just a few bucks nowadays, 40 days of dating and even the cheapest one you can find is good enough for this sort of project.
- Each of the two coils will have a common wire attached to the center of the coil, we don't want to use this wire.
- That means it is not the standard type of motor you described.
- We're working with the pump people now to change the motors.
- The function of a circuit breaker is to provide overload thermal and short-circuit magnetic protection to a circuit and its downstream components.
- It's all sorted out now and running fine.
This has been used in other countries too. Thread Tools Show Printable Version. Red Flag This Post Please let us know here why this post is inappropriate. The V is used in the mining industry. Learned something new today.
This motor uses six wires. Did the wiring cause the bearing failure? Please take a look of the address recomended by dbair. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Unfortunately, that conflicts with your statement that it was running on the higher voltage, right?
Wye Configuration High Voltage
As a stretch, maybe it's old, and there has been a change to the numbering system. In this tutorial I'll show you how we can figure out how to connect the stepper motor to an Arduino and control it using the Adafruit motor shield. What we need to do is measure the resistance from one motor wire to another.
Stardelta, any jobs up there for an old Brush bloke? When I measuring ohm any wire with red wire show half of resistance of any wire combination. The higher voltage connections are the same but the lower voltage connections are different. Resources The function of a circuit breaker is to provide overload thermal and short-circuit magnetic protection to a circuit and its downstream components.
Well, the X, Y, Z terminals are throwing me for a loop. Either the star or the delta arrangement can be re-connected series or parallel for a two to one voltage ratio. Well, it looks as though you are stuck with it being a V motor then, you won't have a lower voltage connection because that is already the low voltage connection i.
For this example that means we want to connect the orange and blue wires, and the white and red wires, we will ignore the gray wire and brown wire, because they have a smaller resistance. It would be rated volts and be capable of being re-connected for use at volts. If the motor, being run with the start windings only caused it to overheat, it would also cause premature bearing failure. Any chance that motor came to you somehow via Brazil? Join your peers on the Internet's largest technical engineering professional community.
The easiest way to do this is with a simple multimeter. This motor is on a big Cincinnati Mill. Thus, mechanical side is more subject for such failure.
Ran into one of my pumps that had its bearing fried. We'll bring you the most relevant peer-to-peer conversations happening in the trade and tips and tricks to help you get the job done. Thank you guys what a great board thank you all for allowing me to be a part of it! Monarch has a series of machines intended for handling material for that industry's unique applications. Usual bearing failure for general purpose motors are more on grease related application problem, misalignment, worn out bearing and loosen bearing housing.
The Eng-Tips staff will check this out and take appropriate action. Life is much easier with only one voltage. Faulty wiring or wrong connection will trigger motor protection to trip. After Brush we moved down to the south coast, and I did a short spell at Allen West before that virtually disappeared.

Are you an Engineering professional? Where is a good source for a transformer no electronics on this dinosuar. Bookmarks Bookmarks Digg del.
There are guys way more qualified than me to answer you, but I will tell you what I have seen. The technician giving me the wrong numbers threw me at first. Do they just over build the coils for this purpose? Your connection diagram is exactly the same as the motors we get in Australia. Here is another example application of a motor shield.
Step 1 Measure and Record the Resistance for All Six Wires
Dag S K Only small european motors are wired in star at their normal working voltage, Larger ones are often started in star then switched to delta after a preset time. We are trying to connect it to V Anyone? The Volts current is the twice of V so you need double connection to support the twice of current. You still see their motor controls and panels all over the place.
