A variable reluctance stepper motor relies upon magnetic flux seeking the lowest reluctance path through a magnetic circuit. This means that an irregularly shaped soft magnetic rotor will move to complete a magnetic circuit, minimizing the length of any high reluctance air gap. WebA transformer core serves the following three important purposes: Provides mechanical support to the windings. Provides a low reluctance closed ferromagnetic path to the magnetic flux. Reduces the losses due to flux leakage. The primary and secondary windings of a transformer are wound over the core but physically separated from each other. crypto terpopuler
