I built an RPC using a 1140rpm, 220v, 2hp motor. I am powering a 850rpm, 220v, 1hp motor. Balance and power factor capacitors, etc. T1 and T2 are incoming/outgoing lines, T3 is generated line. Unloaded voltages and current are as follows: T1-T2=249V and 3.4A, T1-T3=247V and 4.8A, T2-T3=267V and 5.26A. Loaded (1hp equipment motor on): T1-T2=220V and 5.1A, T1-T3=220V and 5.0A, T2-T3=216V and 1.8A. The equipment motor amperes are: T1-T2=4.62A, T1-T3=4.93A, and T2-T3=2.6A Line current (input) is 2.3A unloaded and 4.6A loaded. I have tried various combinations of primary (T1-T3) and secondary (T2-T3) capacitors, and always get the low current on T3 with the 1hp equipment motor on. Has anyone some suggestions on correcting this, or is this normal? I am using the Finch Williams design. zuhnc
