Induction motor
For example; a single-phase motor with 3 north and 3 south poles, having 6 poles per phase, is a 6-pole motor. A three-phase motor with 18 north and 18 south poles, having 6 poles per phase, is also a 6-pole motor. This industry standard method of counting poles results in the same synchronous speed for a given frequency regardless of polarity.

Three-phase motors 101
In a generated 230 or 460 VAC 3 phase system, you should always measure about the same 230 or 460 volts between any two legs, (unless your supply power factor is way off). All of this applies here in the US. Three-phase in Canada, and much of the rest of the world, operates the same but at lower voltages (190 / 380) and at 50 Hz instead of 60.
