1 Phase Motor on 3 Phase Power?
1 Phase Motor on 3 Phase Power?
(OP)
I'm running a 1 Phase 220V Motor (Compressor) at a site that has only 3 Phase power. Hooked up to two lines but motor start is difficult. Power measured at about 205 VAC. I've been told to use a Buck-Boost Transformer? Does this sound reasonable. (I'm only into computers and woodworking)





RE: 1 Phase Motor on 3 Phase Power?
1. Is the 3-phase system voltage 208V/120V?
2. Is there a normal/standard three phase transformer or two overhead transformers on a pole (open delta)?
3. What is Horsepower rating of your motor?
4. What are sizes of the power supply conductors?
The buck and boost transformer may or may not be the solution.

Why not consider using a three phase 208/230/460 Volt motor for the compressor. This will probably require a new motor starter to cycle the compressor on/off with the pressure switch. Once the conversion is made,future changes will be easy and the replacement cost for 3 phase motors are less than single phase when the HP goes above about 1 HP.
