However, the higher cost of rare-earth permanent magnets and the complexity of its controller are some of its disadvantages. Its performance also deteriorates in small format disk drive systems. This paper proposes a four-phase (in-hub) miniature switched reluctance motor with an outer rotor structure for the spindle motor in a 3.5\" hard disk drive. The design methodology of the mini-SR motor is described. The magnetic characteristics, flux linkage, inductance, coenergy and static torque, have been calculated using 2D finite element analysis. The field solutions and the analysis of an electric circuit have been processed to give the description of the dynamic-state performance of the prototype. With a suitable control strategy, the prototype of the four-phase (in-hub) mini-SR motor can meet the basic specifications of the spindle motor in 3.5\" hard disk drives. The development of mini-SR motor provides an alternative spindle motor in hard disk drive systems.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

It is proved through theoretical analysis and experiments that a damper flux-oriented drive system has the same steady performance as that achieved with airgap flux-oriented control; moreover the damper flux is not sensitive to the harmonics of the stator currents, and by using the feedback value, the dynamic performances of the drive system can be improved. A 2500 kW 12/6 Hz cycloconverter synchronous motor drive system with damper flux-oriented control has been manufactured and applied in rolling mills in China.

It uses the per-phase torque characteristics of the motor, which is termed the motor identity, for the optimization of the input current to achieve high efficiency and optimal torque production. This control strategy is described as 'identity control'. A self-starting technique is also developed to start the spindle motor and to operate the motor without sensors. This paper also discusses the implementation of a zero voltage switching quasi-resonant power converter (ZVS-QRC) to achieve high power efficiency by minimizing switching losses in the power devices. Simulation and experimental results are presented and a comparison is made for the identity controlled spindle drive and a BLDCM controlled spindle drive.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

This has been done with a view that graduate students of electrical engineering can perform a variety of experiments in order to replenish their knowledge, on thyristor drives, software programming and to test for aspects of modern control theory which they have studied in their course curriculum. Equal emphasis has been placed for their faculty development both on hardware and software. The DC motor drive system has been experimented on a small, separately excited DC motor. A trapezoidal and triangular speed traction drive has been implemented in this laboratory based on a real-time drive system. The microcomputer based PD, PI and PID controllers determine the rate of acceleration and deceleration of the traction drive with user friendly interactive display control facilities. All the control parameters of the drive system can be set and changed through the keyboard in real-time without affecting the smooth running of the motor.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

The output of the PAM inverter can be controlled by the PFC converter. To reduce the torque ripple in the induction motor a new modulating signal is used for a PAM inverter. The modulating signal has the flat portions of 120-degrees. By using the proposed modulating signal, the amplitude of the fundamental component is increased, the switching loss is decreased and the motor driven by the PAM inverter produces approximately constant torque.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

For the BLDC motor system approximately linearized using the field-orientation method, it is shown that the augmented state variable feedback can be applicable to this system. To overcome the problem of the unknown parameter or the parameter variation such as a flux linkage, a model following adaptive control mechanism is employed for the load torque observer. Stability analysis is carried out using Lyapunov stability theorem. As a result, the robustness can be obtained without affecting the overall system response. The load disturbance detected by the adaptive 0-observer is compensated by feedforwarding the equivalent current having the fast response.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

Although useful for evaluating basic machine parameters, such dynamometers are not satisfactory for examining transient behaviour. A device that can present the dynamic response of a load superimposed on the steady state characteristics of that load is required for transient experimentation. This paper presents the key aspects of a design for such a device-a \"dynamic dynamometer\". Using a control strategy based on local vector (LV) control, a DC machine can be controlled to simulate both the static and dynamic characteristics of a representative industrial load. One particularly interesting aspect of this is that nonlinear effects in real loads, such as backlash and stiction, can be accurately simulated. The paper presents some implementation aspects of dynamometer design, along with simulation results. The structure of the hardware being developed for the system is also discussed.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

SIMNON is a user-friendly tool for nonlinear dynamics simulation, in particular. One powerful feature is its ability of allowing integration of individual program modules after each individual module is programmed and tested independently. This particular feature is exploited here for an AC/DC/AC converter drive simulation. Two methods are used to model the rectifier and the inverter. The first method is to model each thyristor of the rectifier as an ideal switch. The second method is to approximate the dynamics of the rectifier with a set of harmonic equations. A similar approach is applied to inverter modeling. Issues related to the simulation difficulties with each model are addressed accordingly.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

The authors have proposed a novel topology with auxiliary transformer-assisted quasi-resonant commutated pole (TQRCP) circuit which can operate under a principle of zero-voltage switching (ZVS) transition without initial resonant current control loop. In this paper, the high-frequency ZVS-PWM power amplifier which incorporates auxiliary TQRCP circuits into the bridge legs is newly developed for the magnetic-field current tracking control system. The control implementation for achieving a precise magnetic-field current tracking realization with low ripple factor is introduced into the switched-mode PWM power amplifier and its design considerations are described for an efficient generation of gradient-magnetic-fields in magnetic resonance imaging (MRI) machines. It is expected that this technique will improve the image quality of MRI machines.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.
