In this example, two wires are connected together, then both wired to terminal A on the drive. These are desirable when high torques are involved. I also want to post what the exact nameplate lettering was as well. The connection is 1circuit delta. I wish the motour manufacter just put in a quick note to stated that is delta or wye connected motour so we can able speed up the troubleshooting. The motor manufacturer's website has an online selection tool and it has the motor that was specified should be a 9-lead motor. Which I guess must be an indication of the wiring configuration.
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. The thermal protector is an option and does not afect the magnetic performance as far as the windings are correct. Connect 4 to 7, 5 to 8, and 6 to 9. As far as starting at the high speed, this is what I was told about it. Anyway I'll keep you guys up to date on what the end result is but, I think its beginning to look like the motor may have been wired right after all.
What amperage was drainning your motor at 460 V? Probably in order to keep our business. Instead, connect motor lead 1 and 6 to L1 typically black , motor lead 2 and 4 to L2 typically red , and motor lead 3 and 5 to L3 typically blue. The High Voltage Connection is Star, in this case you will find the Voltage Ratio is 1. Does anyone here know if it is possible to derive 2 speeds from this motor? They are not numbered and I am not sure how to hook this up for low voltage. You have been successfully subscribed to the Notification List for this product and will therefore receive an e-mail from us when it is back in stock! This connection is 1 circuit Delta. Normally for Star Delta the leads are marked 1,2,3,4,5,and 6.
Like YoungDen, there are guys more qualified than me to answer this query. If the motor runs normally, all is fine. Thank you guys what a great board thank you all for allowing me to be a part of it! Take an ohm meter and find the leads that have continuity. Bipolar Unipolar drivers, always energize the phases in the same way. The only German I know is from watching Hogans heros reruns.
So its imperative that the connections are right. If don't start or runs slow, swap numbers on the first coil ex exchange T1-T4. Did you check if the name plate is installed on the motor? Well, i dont think wrong or faulty wiring is the root cause of such bearing failure its far beyond usual experience. Next, connect the proper color to the appropriate terminal on your drive. But the tradeoff of course is speed. The disadvantage is that there is less available torque because only half of the coils can be energized at a time.
Join your peers on the Internet's largest technical engineering professional community. The other chance is the motor don´t start an produce noise. They have been delta 440 and wye 220. Ran into one of my pumps that had its bearing fried. We mentioned a catch, earlier. Incidentally, it's for a capacitor start motor, probably 0.
Some motors come with flexible wiring that allows you to run the motor as either bipolar or unipolar. Before you connect any wires, check the drawing carefully. That was not possible at that time. So, for every 100 µF required on 220 volts, only 7 µF is required on 830 volts. And the higher step-rates needed to turn these motors results in lower torque than a similar size low-step-count motor at similar speeds. I personally feel that they should be marking the motor covers with necessary wiring so they can be hooked up as they were originally. Label the next pair T2 and T5 and the last T3 and T6.
All of the six lead motors I am familiar with are connected in a Y configuration for high voltage and Delta for low voltage. One thing is for sure, the motor we have is definitely not the one that we were supposed to have purchased. Unfortunately, that conflicts with your statement that it was running on the higher voltage, right? Bipolar drivers use H-bridge circuitry to actually reverse the current flow through the phases. If that is the case the high and low voltages have to differ by a factor of 1. Indicates that two particular wires are connected to each other, and then connected to the indicated terminal on the drive. Temporaly label one pair T1 on one end and T4 on the other. I think your shop most send a Wiring diagram each they perform a repair in special motors.
