Abstract:
The self-synchronization characteristics of the two excited motors for the nonlinear vibration system with the asymmetrical hysteresis have been proposed in the exceptional circumstances of cutting off the power supply of one of the two excited motors. From the point of view of the hysteretic characteristics with the asymmetry, a class of nonlinear dynamic model of the self-synchronous vibrating system is presented for the analysis of the hysteretic characteristics of the soil, which is induced by the relation between the stress and the strain in the soil. The periodic solutions for the self-s

Abstract:
The hysteresis motor is a well-known synchronous motor that is used in special small power, high speed applications. Dynamic modeling and analysis of this motor is more complicated than permanent magnet synchronous motors (PMSMs) or induction motors (IMs) due to nonlinear behavior of rotor magnetic material. Short over-excitation is a unique phenomenon that only occurs in hysteresis motor in which the terminal voltage increase at synchronous speed for a short duration, and then continuously is decrease to initial value. Therefore, the input current is reduced, this leads to more power factor a

Abstract:
This paper presents the implementation of indirect vector control of three phase Induction Motor using Hysteresis Band PWM current control and Synchronous Current Control in PSIM environment. In any machine drive system, current control directly influences both flux and torque developed directly. In Hysteresis current control method, actual current tracks the command current within a hysteresis band. There is no difficulty in current control tracking when CEMF is low, but at higher speeds, current controller gets saturated due to higher CEMF and hense becomes difficult to track due to which th

Direct-torque-control-driven permanent magnet synchronous machines eliminate the need for a position sensor while providing improved torque dynamics.

Abstract:
Abstract Synchronous reluctance motor drives are one of the most attractive alternatives of permanent magnet synchronous motor drives and induction motor drives in the field of conventional industrial and household applications. This tendency is expected to be continued in the case of motion control applications as well. This article investigates two torque-control algorithms that are possible candidates for motion control synchronous reluctance motor applications. The examined torque-control algorithms are direct torque control (DTC) and hysteresis current vector control (HCVC).

The operation principle of STATCOM (Synchronous Static Compensator - STATCOM) is analyzed. To improve STATCOM response speed, and to sustain the STATCOM main circuit switching device operating frequency stability, the direct current control method is introduced. Fixed frequency hysteresis control method based on the traditional hysteresis control strategy is proposed. The proposed strategy is simple, high precision, fast response speed, while it has less fluctuation with the impact of load parameters, and good robust characteristics.

Abstract:
This thesis deals with the analysis of magnetic losses in electrical machines and the possibilities of their measurement. Magnetically soft and hard materials are very prone to changing magnetic properties. They can be changed simply by changing the temperature of the material or different stresses induced in the material, resulting in different results. These changes are important to keep in mind when an electric machine is being designed. The original parameters of the affected materials can be restored by annealing or grinding. These methods release the induced stresses within the material.

Abstract The basic principles of the ultrasonic motor, which were discussed in Chapter 1, are not difficult to grasp, at least qualitatively.

A mechanical engineer, for instance, should have no difficulty in understanding how the ultrasonic motor works. However, as we have seen in Chapters 2 to 5, the details involved are fairly complex and many aspects of the motor are as yet unresolved. In this chapter we present a metho

The paper critically examines the New Keynesian explanation of hysteresis based on the role of long-term unemployment. We first examine its analytical foundations, according to which rehiring long-term unemployed individuals would not be possible without accelerating inflation. Then we empirically assess its validity along two lines of inquiry. First, we investigate the reversibility of long-term unemployment. Then we focus on episodes of sustained long-term unemployment reductions to check for inflationary effects. Specifically, in a panel of 25 OECD countries (from 1983 to 2016), we verify b
