Standalone Testing Method for Synchronous Reluctance Motors to Determine Their Operating Characteristics

抄録

To realize a decarbonized world, high efficiency in industrial electric motors, including large-sized motors in the range of several hundred kW, is required. Permanent magnet motors are the most efficient for this purpose. However, their adoption in large-sized motors can be challenging owing to the scarcity and cost of rare earth materials. Owing to this, synchronous reluctance motors (SynRMs) are gaining attention. They do not use permanent magnets in the rotor and are more efficient than the widely used induction motors. However, to determine the operating characteristics of SynRMs, an actual load test is necessary. For large-sized SynRMs over in the range of several hundred kW, conducting this test is expected to be challenging owing to the requirement of large test facilities. This paper proposes a method to examine the operating characteristics of SynRMs using a standalone test and reports the evaluation results of the proposed testing method. This method provides a practical solution for evaluating the performance of large-sized SynRMs, potentially facilitating their wide adoption in industrial applications.
