OK group... what am I missing? I just bought a brand new surplus, 1 HP
commercial Phas a Matic rotary converter. Retails for $405.00 new.. bought it for $50.00. I figured it was worth 50.00 as it is truely brand new. Went to their website http://www.phase-a-matic.com/RotaryDescription.htm , read all the great stuff about how good their rotary is blah, blah blah , and well, I figured got a good deal. So lets see whats inside...... Opened up the metal enclosure on top to see the guts of the unit and what do I see.... nothing but a SINGLE 30 microfared oil filled capacitor. No potential relay, no banks of capacitors to balance the phases, no fuses, no nothing else. One single starting capacitor. THIS is worth $405.00 retail.. a 1HP Baldor motor with one single 30 uf capacitor????? Is there something special in the rotor of the motor that I am missing? Is there something in the wire? Please someone let me know why and how Phase a Matic gets away with this BS!!! Steve Koschmann Second question... can I parallel a standard 2HP 3 phase motor with this 1 HP unit and try to get a 3 HP converter going? Should I balance the phases of the 1 HP unit and or the combined 1 and 2 HP (=3 HP) units? Steve |
