The rim and the rotor have serrated iron poles offset from each other. The reluctance torque is created due to the reluctance (variable magnetic resistance) with respect to the position of the rotor and rim. The force acts in such a way that the tooth of the rim wants to be placed in an aligned position of maximum inductance or minimum reluctance. After the rotor is placed in an aligned position, the next phase is powered in relation to which the rim is in an unaligned position, and a force occurs that rotates the rotor again to a new aligned position. Each phase is powered independently from its branch of the asymmetric half-bridge converter.

In this version, the windings are connected in series to reduce the input current. The drive is with switched reluctance.

ADVANTAGES: Simpler and cheaper design – the windings are only on the stator, there are no windings or expensive permanent magnets on the rim, there is less heating, the electrical error of one phase does not affect the other phase.
