Kurzbeschreibung (Abstract)
Ferrite magnet assisted synchronous reluctance motors are prone to demagnetization at high overload torque or electric failures (e.g. sudden short-circuits). A four-pole 11 kWprototype motor was partially irreversibly demagnetized by a three-phase sudden short-circuit test on purpose. Here, the remagnetization process of the demagnetized ferrite magnets by transient inrush currents that occur when the motor is externally driven at rated speed (1500 rpm) and suddenly connected to a sinusoidal grid (400V and 50 Hz) is investigated. Measurement results of the original prototype (I) are compared to the partial demagnetized (II) and the partial re-magnetized (III) ferrite magnet assisted synchronous reluctance motors. At rated load operation (1500 rpm, 70 Nm) the efficiency values (IE4: 93.3%) are slightly reduced from 93.6% (I) to 93.2% (II) and 93.5% (III), while the power factor values are 0.83 (II) and 0.86 (III) compared to 0.88 (I).
