Q1: What causes a motor to turn?
A1: There are two parts to a motor: a stator, or field, and a rotor, or armature. Around one part there exists a magnetic field from the line current, and in the other part there is an induced current that causes a magnetic field of opposite polarity. These magnetic fields repel one another, thereby causing the rotating member to turn.
Q2. Why would you use a phase splitter and a three-phase motor instead of a single-phase motor?
A2: It is possible that at the moment single-phase power is all that...
