Abstract :
This paper presents a new method which is based on directly applying Ampere´s circuital law and Gauss´ divergence law to analyze PM motors, which we call the Direct Ampere-Gauss Analytical Method (DAGAM). This method can be used to calculate the motor´s main performance as well as its secondary characteristics such as cogging torque and back-EMF waveforms, which are important considerations for motor optimization. A comparison of the results using DAGAM and FEA is presented to discuss the accuracy and efficiency of DAGAM. Some applications of DAGAM in optimizing the design of permanent magnet motors are presented.
