Power Corrupts, Three-Phase Power Corrupts Absolutely
Toolmonger: "Three-phase power used to be one of those things that separated the professionals from the amateurs — but now, with the availability of inexpensive AC drives, you can easily run three-phase equipment in your shop. In the past, phase converters were large and expensive, and in some cases they decreased the motor’s power. Inverter technology has solved all of those problems."

Thank you ToolMonger! Its always so nice when large professional items are introduced into the public domain for everyone to use. In the post, the guys is talking about his lathe, now the everyday guy can have his own lathe now that he can get this tool. Isn't technology great!
Does it really mater if your lathe is single phase or three phase. If a single phase motor can do the same thing I see no reason to pay for a three phase motor drive. Sometimes people will spend money on things that are completely unnecessary just to make themselves seem “professional” or important.
Lenny, three phase motors are far more efficient than single phase motors, and many "professional quality" tools aren't available in a single phase version. Also the desire to use three phase tools partially stems from the availability of older "professional" tools that are still good but have been upgraded in professional shops.
