The inverse method that we use involves minimizing the residual between the machine's internal losses and the total amount of heat extracted to ambient air in a thermal steady-state condition. First, we start by establishing the initial conditions for the optimization algorithm. Then, we introduce an optimal law of variation of heat exchange coefficients for different thermal phenomena. Finally, this approach is tested for different operating conditions to certify its validity using data extracted from tests performed on an internal permanent magnet synchronous machine.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"72 1","pages":"1115-1123"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85930400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The output torque with the 3rd harmonic current is analytically established and the optimal value of 3rd harmonic injected into the current waveform for maximum torque improvement is analytically derived and validated by finite element (FE) analyses. It is found that the optimal 3rd harmonic is dependent on the ratio of third harmonic back-EMF to the fundamental one but not 1/6 of the fundamental one as pulse width modulation in inverter. For the 10-slot/8-pole and 40-slot/8-pole five phase SPM machines having the same PM rotor, the electromagnetic performance including the back-EMF waveform, average torque, copper loss, and iron loss, are compared considering the 3rd harmonic current injection. The torque can be improved for both of the machines by injection third harmonic current under the peak current constraints, whilst only 40-slot/8-pole machine can have higher torque when 3rd harmonic current injection under the same rms value constraints.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"29 7 1","pages":"630-636"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82734285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PMa-SynRM is the hybrid structure of interior permanent magnet (IPM) motor and synchronous reluctance motor (SynRM). In this study, an optimized 15kW five-phase PMa-SynRM has been proposed as a better substitute for three-phase IPM motor for ISG operation in Honda Civic Hybrid car. A new reverse engineering technique (RET) has been applied to model the Honda IPM ISG. In order to develop a better PMa-SynRM ISG, the model developed using RET has been used as reference. Thorough analytical and finite element analysis have been performed to obtain the optimal PMa-SynRM design which has better performance characteristics compared to the Honda IPM ISG. Lumped parameter modeling (LPM) has been utilized with differential evolution (DE) optimizer to extract the best optimal design for the five-phase PMa-SynRM ISG. For the same power and volume, five-phase PMa-SynRM design has shown better performance characteristics in terms of cogging torque and torque developed.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"63 1","pages":"433-439"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83071920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Droop control is also included in the control loop. The underlying inverter is designed with voltage and current control loops in the dq-frame and proper filtering and coupling inductors are included. The synchronous machine is also modeled as a generator represented by model 2.1 of the IEEE Std. 1110-2002.

In this work, an innovative method is presented and developed for the online identification and correction of the electrical parameters of electrical machines based on cluster technique. This technique allows for the estimation of all electrical parameters with low computational cost. It uses the information of stator currents, stator voltages, and rotor angular speed. The algorithmic performance has been tested using simulation data of a 75-kW permanent magnet synchronous motor for electric vehicles.

The studied machine is designed for the application in electric vehicles and has a maximum output power of 53.6 kW. The acoustic noise of the electrical machine is mainly generated due to vibration of the stator yoke, which is caused by the radial forces acting on the stator's teeth. The radial force is directly correlated with the flux density in the air gap. Through modification of the outer frame of the rotor, the composition of the air gap field, which consists of the fundamental wave and its harmonics, can be modified. The distribution of the radial force density on the surface of the stator teeth will be affected and the dominant order of the radial force can be reduced selectively, which will improve its acoustic behavior.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"67 1","pages":"1359-1365"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77888768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
