How Do You Build Rotary Phase Converters?
Constructing a rotary phase converter is the perfect solution for small shops that may have restrictive access to three-phase power. A good understanding of motors and electricity is needed before attempting to build and install a rotary phase converter. Calculate the amount of horsepower you want to run from your rotary phase converter. You can easily operate a number of motors from one phase converter. The total load should never exceed more than 80% of the rated load for the phase converter. Example for load calculation would be utilizing a 10 hp (horsepower) phase converter should only run up to 8 hp in load. Connecting the rotary phase converter is a very easy task once you have the load figured out. You must also have the proper sized capacitor for the load demand placed on the motor circuit. A great rule of thumb is 40 MFD (Micro Farad) per hp. In the use of capacitors more is better and less is not. These capacitors should be of the oil filled type. It may take some experimenta
