    3 phase motor interesting ohm readings

    Additional information, after discussion I meggered 4,5,and 6. 4 = 343M ohm to Gnd 5 = >1G ohm 6 = 343M ohm Interesting so I measured and 4 t0 6 are shorted. So evidently I had a phase to phase short which ble open to the line side causing these readings. by why an internal phase to phase...

    3 phase motor interesting ohm readings

    Customer returned a burnt up motor. 460VAC 1HP. Nothing special about the motor or application other than the load does shift in a cyclical pattern. We are driving an offset cam. Initial inspection looked good. Wires 1,4,7 are red 2,5,8 are black and 3,6,9 are white. It is a dual voltage...

    Hitachi MLFC wire

    We're looking for something generic and inexpensive that we can install on any OEM CNC machine without having to engineer for each make and model. Using the current transducer and having the customer clamp it on the motor / drive input lead seems like the simplest way. I agree the drive output...

    Hitachi MLFC wire

    I was setting up a chip conveyor speed control and was going to use a current tranbsducer on the spindle drive AC input as my speed reference. As the spindle drew more current (cutting deeper and making more chips) the chip conveyor speed would increase. However I cannot get a current read...
