WebThe synchronous electric clock has no timekeeping properties in itself and is wholly dependent upon the frequency stability of the alternating current supplied. If this … A reluctance synchronous motor is synchronous motor in which the rotor is a temporary magnet made from a magnetically soft material. There are some differences in detail but most reluctance synchronous motors used in clocks have the same main features. An exception is the Marigold movement … See more As the name of a magnetised synchronous motor implies, the rotor is permanently magnetised.
