Abstract

An electrical synchronous machine (1) comprises a rotor (20) with rotor field windings (22) and a stator (10) with stator windings as well as a rotor power supply (50) and a stator power supply (60). The rotor power supply (50) is arranged to supply rotor field current for causing a magnetization of rotor magnetic poles (24). The stator power supply is arranged to supply alternating stator current for causing a rotating stator magnetic field. The electrical synchronous machine (1) further comprises at least one sensor (30), arranged to measure a quantity that is dependent on a relative angle between the rotor (20) and the rotating stator magnetic field. The electrical synchronous machine further comprises a rotor magnetization control arrangement (40), arranged for repeatedly varying amplitude and/or direction of the rotor current as a response to a change of the measured quantity. A corresponding control method is also disclosed.
