摘要: Interior Permanent Magnet Synchronous Motor(IPMSM) have gained an increasing popularity in recent years for a variety of industrial applications, because their high power density, efficiency and possibility flux weakening operation. Because the IPMSM is one important performance characteristic, Maximum Torque Per Ampere(MTPA) operating method has been indispensible. In theory, MTPA point can be calculated using exact values machine parameters. However, parameters are known to vary widely according condition. Therefore, operate point, should estimated real-time. this paper, new based on signal injection presented. By injecting frequency current signal, criteria by measuring input IPMSM. The proposed find with simple processing regardless parameter variation.
