“…Alternate QD Model (AQDM) simultaneously included magnetic nonlinearties and the distributed nature of rotor circuits which CQDM in [9][10][11][12][13] has deficiency in representing over all possible operating conditions due to its constant parameters. Stator and rotor leakage inductance, and the absolute inverse magnetizing inductance are expressed as function of magnitude of magnetizing flux linkage, m λ , which is equal to 2 qm λ , and are denoted The steady-state equivalent circuit representing the AQDM in [14] is shown in Fig.…”

“…Among many efforts to obtain efficient operation, an Adaptive Maximum Torque Per Amp (Adaptive MTPA) control of induction motor drives was validated to drive induction motor in highly efficient way [7,8]. That is because it employed an alternate qd induction machine model (AQDM) rather than the classical qd model (CQDM), such as in [9][10][11][12][13].…”

-Efficient operation of induction motor at light loads has been getting wide attention recently because the operating of induction motor at light loads occupies big portion of its operating regions in many applications such as environment friendly vehicle. As one of approaches to improve efficiency, Adaptive Maximum Torque Per Amp (Adaptive MTPA) control for induction motor drives has been proposed to achieve a desired torque with the minimum possible stator current. However, the Adaptive MTPA control was validated only at heavy load where, in general, control scheme tends to perform better than at light loads since the error in measurement of sensors is lower and signal to noise is better. Thus, although the performance of a control scheme is good at rated operating point, its performance at light load is somewhat in doubt in practice. This has led to considerable interest in efficiency of Adaptive MTPA control at light loads. This work experimentally demonstrates performance of Adaptive MTPA control at light loads regardless of rotor resistance variation, thus showing its good performance over all operating conditions.

[1]- [7] 과 IEEE 논문 [8] AbstractMany efforts have focused on the improvement of power density and efficiency by downsizing the motor and inverter. Recently, Toyota, Honda, and GM realized that the compact-sized motor uses the hairpin structure with increased space factor. Reducing the maximum torque from high-speed technique also makes it possible to design the high-power density model. Toyota and Honda used the newly developed power semiconductor IGBT to decrease conduction loss for high-efficiency inverter. In particular, Toyota used the boost converter to increase the DC link voltage for high efficiency in low-torque high-speed region. Toyota and GM also used the double-sided cooling structure for miniaturization of inverter for high-power density.

Acoustics comfort is an increasingly important factor at the design stage of electrical machines associated with converters. Skewing has a direct impact on pressure in the air-gap, which can be responsible for electromagnetic noise. This paper aims to compare different models to study the skewing. The impact of pressures is evaluated and analyzed for no-skew and skew rotors. Three numerical electromagnetic models are compared: 2D finite element method (FEM), 2D FEM multi-slice and 3D FEM. In addition, an experimental measurement validates our results.Ke y words-Maxwell forces; air-gap radial pressure; spatial order and frequenc y ; finite element anal y sis; anal y tical anal y sis; skew rotor;
