    Three phase 200 volt motor

    Why does Baldor (USA) make a 200 volt motor. Should one be wary of running this motor on 245 volts?

    Transforming converter voltage

    Converting 3 phase voltage from 230 to 600 on a y -delta transformer should one be concerned about the high reference to ground in the generated phase. Should you disconnect the reference to ground...

    Self assembled rotary Phase Converter

    I have been building rotary Phase Converter’s for a number of years. Here is a recent build using a TD relay to drop out the start capacitance and energize a contactor for an remote load. 258650

    Thanks for the good responses. It is my understanding that a split phase motor has more starting torque than a three Phase motor. In this case if the screw had a three phase motor, the starting...
  12. Excessive amp draw on screw compressor upon start

    Friend ordered a screw compressor with a single phase 7.5 hp motor. When he starts it it dims the lights to his whole acreage. He is 60 ft from the pole so voltage drop is not an issue. What could he...
