Torque ripple minimization in Consequent-Pole PM Machines using harmonic current injection
نویسندگان
چکیده
In this paper, the torque ripple of consequent-pole PM machines (CPPMMs) is reduced by injecting 2nd order harmonic armature current. into stator coils. proposed method, based on machine back-emf spectrum and main load current, appropriate current obtained. An analytical model developed to obtain CPPMMs. addition, obtained used compute electromagnetic as a function currents. Validity verified using finite-element analysis. To investigate efficacy in minimization, optimum one separately direct search algorithm related waveforms for two different harmonics are compared together. The waveform computation. Although method not exact it precise enough considering its negligible computation burden over method.

متن کاملTorque Ripple Minimization in Hybrid Stepper Motors Using Acceleration Measurements ?
Hybrid stepper motors (HSMs) are commonly used in many cost-sensitive industrial and consumer applications. With the use of micro-stepping techniques, they could theoretically achieve a very high resolution in positioning of mechanical loads, even without position sensors. However, it is well known that HSMs are affected by a large torque ripple, due to cogging and phase unbalancing. This, in t...
