    GE AC motor wiring
    Greetings! I just purchased a new surplus AC electric motor and need help with wiring it to the plugin and switch. Keep in mind please that I have no wiring experience and can't read a schematic anymore that I read Russian. Here are the specs from the motor:

    GE Motor
    Model # 5KC32GN19H
    CAT# C250

    The following specifications are per the manufacturer

    HP:1/4
    RPM:1725
    Volts:115/230
    Enclosure:Totally Enclosed Fan Cooled
    Type:Capacitor Start
    Frame:56
    Bearings:Ball
    Rotation:Reversible
    50Hz/60Hz:No/Yes
    SF:1.00
    Protection:None
    Base:Welded Base
    'C' Dimension (inches):10.4
    Full Load Amps @ N.P. Volts:5.4/2.7
    Model Number:5KC32GN19H
    Item:AC Mtr 1/4 HP 1725 RPM 115/230 V 56 FR Capacitor Start TEFC
    Catalog Number:C250

    Here is a photo that shows wiring:

    Thank you for any assistance you may be able to provide and happy holidays to all!

    Well, for starters you could try telling us whether you need it wired for 120 volts or 240volts. Also a closeup picture of wiring diagram will help, can't quite make it all out in that picture.

    I can read it. Are you wiring for 120 or 230?

    It's pretty simple if you pay attention to the wiring schematic... what direction do you want the motor to spin... clockwise or counter clockwise and what is the voltage you plan to run this motor on? (direction is determined by looking at the shaft)

    I had no idea how to help.

    Edited: Added small correction,

    Mis, the technical "front" of a motor is the bell end, opposite the shaft. Looking at the bell end is how CW and CCW is determined.

    Note on nameplate it states "viewing lead end of motor".

    TK, you are correct about this motor, it says so on the name plate. But unless otherwise marked (as in this instance) direction is always determined by the shaft end, not the bell end as you stated. Most often when that notation is made on the nameplate it is because the motor has a shaft which extends through both ends of the motor. There are some exceptions, of course, perhaps in this case. Thought you might like to know.

    Now HERE is a subject that I'm good at, I've installed dozens of motors!

    For 120 volts CCW operation

    Connect Black, White, and Yellow to one lead (hot)
    Then connect Blue, Orange, and Red to the other (Netural)
    Then ground it via the ground terminal.

    For 230 volt CCW operation

    Connect Black and Yellow to one lead
    Then Connect Blue to the other

    Then connect Red, White, and Orange together

    Ground the motor using the ground screw.

    It's hard to read, but it looks like in order to reverse rotation (CW) Black and Red leads must be swapped, so in this case:

    For 120 volts CW operation
    Connect Red, White, and Yellow to one lead (hot)
    Then connect Blue Orange and Black to the other (Netural)
    Then ground the motor

    For 230 volts CW operation

    Connect Red and Yellow to one Lead
    Then connect Black, white and orange together
    Then connect Blue to the other lead.

    Ground the motor.

    That should do it.

    I don't know how you plan to control (operate it) but if you want it hooked to a switch, then for the 120 volt set up, install the switch in series with the hot lead. (black wire coming from the source (outlet?))

    For 230 volt set ups, I recommend a double pole switch in series with both hot leads.

    15 amp switches should do according to the data plate.

    Made in the USA - well done!

    Missouri,

    Can you explain why every source I can find, such as the following glossaries:


    PTplace.com
    Electric Motors - Electric Motor Manufacturers - Electrical Motors
    Electric Motors - Glossary F
    Reliance - Motor Glossary
    http://www.ab.com/support/abdrives/d...on/fb/1022.pdf

    All state in similar words:

    The front end of a normal motor is the end opposite the coupling or driving pulley (NEMA). This is sometimes called the opposite pulley end (O.P.E.) or commutator end (C.E.)

    Elsewhere you can find that a double shafted motor the front will be the lead end of the motor.

    Good info, TK... But the shaft end, aka the drive end is the source for determining the rotation... as I mentioned.
