N9 leads out motor connection books

I now get to customers before they even start shopping the transfers play a big role in building. In such case, each cable will be marked with the appropriate lead number. In this lesson well learn to read and interpret motor connection diagrams and determine the electrical relationship of the stator windings using motor connection diagrams. A megger is the best way to see if any of the leads show leakage to the frame of the motor. Motor connections vary depending on 1 or 3 phase, y vs delta, and many other factors. Each lead may have one or more cables comprising that lead. Delta connected, 9lead motor dualvoltage and can be. The leads are numbered to aid the electrician when connecting the motor. If leads 123 and 546 are swapped, the motor will probably run on the high speed connection, but it will be noisy and the speed will be identifying unmarked leads of 6lead motors with 1 or 2 windings procedures also help identify type of connection when there is no nameplate table 3. Available for low 1 kv and medium voltage 58 kv applications, 3m motor lead connections and kits are designed to withstand extreme industrial environments abrasion, moisture, grime and temperature extremes. Each motor will have 9 numbered leads coming out of the motor. Heres what a few of them say about connected leads.

Each csa and nrtl certified kit contains everything you need to make three splices. Single voltage shunt fields have only two field leads f1, f2 while dual voltage shunt fields have four field leads f1, f2, f3, f4. Car music interface, aux charging y cable coiled cord, 3. Body size wt0 erg4002 erg4005 tbm45s tbm6,tbm6s tbm5, tbm5s. Next, use an ohmmeter to determine if the motor is y or delta connected. Test light or ohmmeter lowvoltage dc source 6 or 12volt battery lowscale dc voltmeter must be analog numbered lead labels the motor must be assembled the rotor is needed to complete the magnetic circuit.

We have a long list of clients, who come back again and again, thanks to the high quality leads were able to provide. Working with live transfers has added a new dimension to get my sales up. Terminal markings and internal wiring diagrams single phase and polyphase motors meeting nema standards see fig. The last few pages of the parts books contain assembly kits and repair kits such as lower unit assemblies, powerhead assemblies, carb kits, water pump kits, gasket and seal kits, electrical kits and more. How to identify motor leads in their order coming out from. If you look at the manufacturers nameplate it will have a table similar to table 1 that describes how the leads should be connected. Unless it is a two speed motor which is highly unlikely in a rpc all motor leads are wired up and connected in any dual voltage motor 12 lead motor. Identifying unmarked leads of 6lead motors with 1 or 2. Manufacturers nameplate for delta connected 9 lead motor. Identifying unmarked leads in a ninelead threephase motor. A yconnected motor will have 3 groups of 2 wires each which show nearly 0ohms between each pair, and a 4th group which shows near 0ohms between 3 wires. Washing machine motor wiring basics let me show you how to wire a washing machine motor the basics stuff for transform this universal motor in a washing machine motor.
