    That’s actually a little high for resistance on an ac 480 or 600 volt motor it should really only read 3 ohms or less most normal reading is .5 ohms

  • @shamanking5195

    Hi everyone. can someone tell me what could be causing high amps on two legs only ??? motor voltage = 460 motor amps rating = 283 Line 1 voltage to ground = 278 Line 2 voltage to ground = 281 line 3 voltage to ground = 280 Motor connection are secure , there is no loose connections. we Megged the motor and cables and shows over 2k megaohms . motor amps when running Phase A amps = 280 Phase B amps = 292 Phase C amps = 285 as you can see only one phases is below the name plate rating but still little bit to high. There is no enough voltage imbalance to explain the high current on the two phases . why is the high current in two phases only ??? motor was rebuilt recently. Anybody has any idea what our problem is ??? Any suggestions ???

    Hello there, thanks for making this video. I just wanted to comment about the inductance values you mentioned. Like you said it’s helpful if the value in Henry’s is known. If it is then the inductive reactance can be calculated by XL = 2(pi)fl, then that value can be squared off along with the resistance value and added together then square rooted. The result should give us the Impedance value.

    So is low voltage 240 single phase or 240 3 phase?

    • @jhooah1
      @jhooah1 8 หลายเดือนก่อน

      It's a 3 phase motor, your just changing the voltage setup, not the location of the windings, so it's manufactured as 3 Phase and cannot run single phase.(either 230 V or 460V depending on how you configure the wiring of the coils)

  • @jimkillen1065
    @jimkillen1065 ปีที่แล้ว

    I appreciate the information, it helped me to determine the correct numbers on the wires . The little metal tags were very hard to read . So i used this method and checked the condition of the windings . . What a learning experience especially trying to get the motor to run properly with a phase convertor. I going to buy a vfd and use it on the bridge port mill. Thanks

    • @v4lhulme
      @v4lhulme 8 หลายเดือนก่อน

      Just remember to check rotation direction. If it's spinning backwards just swap L1 with L2 OR L2 with L3 OR L3 with L1. Basically just swap any 2 and it will change direction.

  • @jeffgerst3619
    @jeffgerst3619 2 ปีที่แล้ว

    Good video. All coils are used irregardless of the supply Voltage. High voltage uses the +3 method for connecting the leads together and low voltage connects the windings in parallel with each lead connected to 1 and 7, 2 and 8 and 3 and 9 with 4-5-6 connected together just like 10-11-12 are from the factory. Hig voltage connects windings in series.
