If that is the case the high and low voltages have to differ by a factor of 1. Try with the shop some course about it. European countries and Australia only have one voltage for low voltage 3 phase supplies so multitap windings like the 9 wire type are unnecessary in such countries. Static converters are made for these motors, and the capacitance required at 830, vs. 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.
Normally will the motor work optimally at 60 hz at a approximately; voltage 1. Good Connection : Low L1- 1 L2- 2 L3- 3 4-5-6 Open 1 Delta This could explain why the motor don´t work proper. Determine how many lead wires your motor has 4, 6, or 8 wires. Connect motor lead 1 to L1 typically black , motor lead 2 to L2 typically red , and motor lead 3 to L3 typically blue. I would assume at 50 hertz, where this is a German motor. Well, the X, Y, Z terminals are throwing me for a loop.
To operate at 230 Volts you made external conection called double connections and to operate at 460 V you connect in single connections, the wye or Delta Connections depends of winding design but the 9 leads Motors can´t start in star delta starting. I personally feel that they should be marking the motor covers with necessary wiring so they can be hooked up as they were originally. All of the six lead motors I am familiar with are connected in a Y configuration for high voltage and Delta for low voltage. This is because of the way stepper motors are made, stepper motors will have two coils and since this motor has six wires that means there are 3 wires per coil. Monarch has a series of machines intended for handling material for that industry's unique applications.
If this one is wired for high voltage as stated over the low voltage shold be approx 240 V The power shold be fed into U;V and W. I didn't understand any other words on the instruction plate of the motor or control transformer. Huge motors may have other voltages, usually with a voltage difference of about 1. Indicates that two particular wires are connected to each other, and then connected to the indicated terminal on the drive. Ideally, you will be connecting motors per an installation drawing. How do you get that dual voltage rating with a 6 lead three phase motor? Two speed starters make the required connection when the six motor leads are connected to the corresponding ports of the starter.
Miniature versions of these can be found as head positioners in many disk drives. We mentioned a catch, earlier. Dgarland, how big is the motor? Did you check if the name plate is installed on the motor? Connect the remaining leads 4, 5, and 6 together. The 230 Volts current is the twice of 460 V so you need double connection to support the twice of current. Can anyone take a stab at this.
Take an ohm meter and find the leads that have continuity. If you don't have one, it's worth buying one as you can get one for just a few bucks nowadays, and even the cheapest one you can find is good enough for this sort of project. Thank you guys what a great board thank you all for allowing me to be a part of it! That would fit with your description as this being connected for the lower voltage. It is required that it already be rotating at the 1800 rpm setting. I had a connection diagram but I couldn't upload it because of its size so I'll try ro describe it. This connection is 1 circuit Delta. Tesla, that's what I was thinking, my father in law who's a retired maintenance electrician said the same thing.
If it won't run reverse T3-T6. Like YoungDen, there are guys more qualified than me to answer this query. If the motor hums on high speed when the shaft is free no load the winding is wrong. 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. If you have a 6 lead motor, the only two ways to connect it are wye or delta. In this lesson we'll learn to read and interpret motor connection diagrams and determine the electrical relationship of the stator windings using motor connection diagrams. This 230 has been used in other countries too.
This is what you need to look at to decide if the motor has the strength to do what you want. Join your peers on the Internet's largest technical engineering professional community. Well, i dont think wrong or faulty wiring is the root cause of such bearing failure its far beyond usual experience. If you have a Bipolar drive, the terminal on your drive will be labeled A, A-, B, B-. Does anyone here know if it is possible to derive 2 speeds from this motor? These are desirable when high torques are involved. Lately, I have had to hook several European - German motors.
Some motors come with flexible wiring that allows you to run the motor as either bipolar or unipolar. As far as starting at the high speed, this is what I was told about it. 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. Typically, the motor will be a 6-lead or 9-lead motor. Check if your electricians needs to know more about this special motors.
Meanwhile I had them bring the motor in question back to the shop for some experimenting. The 6 leads are what's throwing me. The motor manufacturer's website has an online selection tool and it has the motor that was specified should be a 9-lead motor. It should be good on one on one of these connections. 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! A two phase bipolar motor has 2 groups of coils. I also want to post what the exact nameplate lettering was as well.
