- 要約等...or control for induction motors using an adaptive flux observer makes it difficul......to output high and stable torque at a standstill condition when the output voltage error mainly due to dead-time of the inverter. This voltage error leads to a speed estimation error. Consequently, axis misalignment occurs, and a torque value that tracks the reference command value cannot be output. A method has been proposed to compensate for this voltage error by using a current command value; however, the compensation accuracy is limited because of the forward voltage drop and nonlinear characteristics of power switching devices. This...

- 要約等A characteristics calculation of induction motors is rather complicated in closed-slot induction motors. The inductance of a closed-slot bridge, that is, its leakage reactance has been problematic due to saturation of a magnetic steel sheet at a bridge. In this paper, the inductance characteristics of a closed-slot induction motor are studied with an experiment and finite eleme......t method (FEM) analysis. In the experiment, the flux linkage of a model rotor was measured by a search coil and was compared with FEM results.

- 要約等In previous studies, we applied reluctance network analysis (RNA) to the dynamic analysis of the induction motor. However, the accuracy of our analysis of the motor characteristics using the RNA model was not high because the detailed magnetic flux distribution in the rotor was not taken into account. In this paper, we propose a 3D RNA model that considers the detailed magnetic flux distribution in the rotor and skew of the rotor bar. Using the proposed RNA model, the winding currents of the induction motor under no-load and locked rotor conditions can be calculated with higher accuracy than with the previous RNA model.

- 要約等<p> This study presents instantaneous inductance estimation and a sensorless stroke estimation method of a linear resonant actuator (LRA). In LRA, the stroke information is most important since the maximum distance of the mover is not mechanically constrained. In order to estimate the stroke from the voltage equation, motor parameters such as effective resistance, effective inductance and force constant are required. Especially, the inductance of LRA may change due to magnetic saturation. Therefore, it is necessary to estimate the inductance during operation and update its value continuously. This paper proposes a method to estim...

- 要約等In this paper, the analysis and the modelling of a Dual-Stator Induction Motor (DSIM) are presented. In particular, the effects of the shift angle between its three-phase windings are studied. A complex steady state model is first established in order to analyse its harmonic behavior when it is supplied by a non-sinusoidal voltage source. Then, a new transformation matrix is proposed to develop a suitable dynamic model. In both cases, the study is made using an arbitrary shift angle. Simulation results of its PWM control are also presented and compared in order to confirm our theoretical observations.
