Synchronous motors (DC)

Since the permanent magnet is integrated into the synchronous motor, the motor´s field doesn´t need not be introduced into the motor via an external current source (cf. asynchronous drive). This makes it possible to build drives with an high efficiency rating despite their small size. Synchronous motor technology yields fundamental advantages over the asynchronous motor in the form of more compact dimensions, higher efficiency and greater speed stability under load (such as for scanner operation).
