There are ideal ratios of stator-to-rotor poles, depending upon motor type/desired output characteristics. Reluctance motors usually come in pole ratios of 6/4, 4/2, 8/6, or 12/8, though more ratios exist. A 1/1 ratio works best for synchronous reluctance motors, as it allows for more precise synchronism. Rated power/torque

Reluctance is an engineering term that means that when you create an electromagnetic field, any steel part that is located near that field is reluctant to remain un-aligned with the field that is provided. The electromagnetic field will exert a strong force onto any steel part near it to align with the invisible magnetic field.
