A Single-phase Spindle Motor Design for DVD Application

材料科学技术学报 , 2000,
Abstract: A single phase brushless spindle motor with innovative design has been developed for application in a DVD drive. The methods used to reduce the cogging torque and to improve the dynamic performance of this new design motor are proposed in this paper. The single phase brushless spindle motor is usually applied for cooling fan, pump and blower before the performance is improved by the reengineering process. The stator configuration and the drive circuit have been remodeled in order to meet the requirements of the spindle motor used in the DVD applications.

International Journal of Engineering Trends and Technology , 2012,
Abstract: In Industrial applications, two forms of electrical energy are used: Direct Current (DC) and Alternating Current (AC). Usually constant voltage, constant frequency Single-Phase or Three-Phase AC is readily available. However, for different applications different forms, magnitudes and/or frequencies are required. This paper proposes how the Three-Phase inductive load is run by a Single-Phase supply by using Cycloconverter and a Scott-T connected Transformer. The controlling of a ThreePhase Induction Motor is done by Frequency variable method. Single-Phase to Three-Phase for motors offered by using high in performance, low on maintenance and is used to reduce of breakdown of electrical equipment, our range is also suitable for saving energy and require low maintenance.

Research Journal of Applied Sciences, Engineering and Technology , 2013,
Abstract: This study deals with the optimization control of a single-phase brushless DC motor (BLDCM) with Hall sensor. A simple modeling method with feasible parameter identification is adopted to meet characteristics of single-phase BLDCM. With the linear Hall sensor feedback, the advantages of current-mode control scheme and soft-commutation scheme are proposed to achieve maximum efficiency over the entire speed range. This thesis also develops a low-cost and high efficiency control for single-phase BLDCM. The hardware test platform has been constructed on a single-chip Field Programmable Gate Array (FPGA) of Cyclone II Family of Altera to verify the performance and feasibility of the proposed optimization control strategies. When using the control scheme with Hall sensor, experimental results show that there are at least a 10% improvement for average value of dc-link current, a 10% improvement for RMS value of phase current and a 40% improvement for peak value of phase current.

International Journal of Advanced Research in Electrical, Electronics and Instrumentation Engineering , 2013,
Abstract: :AC drive systems have been widely accepted for industrial applications. In general, they take the advantages of a higher power density and a higher efficiency than DC drive systems. This paper presents a novel chaotic-speed control of split-phase induction motor drives, especially for application to cooling fans. Based on the state vector analysis of the system, the d qaxis model of the split phase induction motor is deduced. It reveals the periodicity and chaos for various system parameters. Mathematical analysis, computer simulation and experimental results are given to testify the proposed chaotic-speed fan.

Journal of Engineering and Applied Sciences , 2012,
Abstract: Questions of great interest deserve to be raised in the precise calculation of the single phase induction motor. They relate to the influence of the active losses in iron and of the higher harmonics on the technological performances. These problems were developed a little for the symmetrical machines. On the other hand, they were the subject often of negligence in the research tasks for the actuators of low power. Their consideration more complicates the mathematical models and consequently calculations of the technological performances. The consideration of these two non linearities made it possible to improve rigorously precision of the calculation of the mechanical characteristic and the energy indices of condenser micro motor. The results obtained as well theoretical as experimental confirm well the considerable impact of the losses iron and the higher harmonics on the characteristics. This constrained to hold account of it in any calculation of optimization of the asynchronous condenser micro motors.

Journal of Electromagnetic Analysis and Applications (JEMAA) , 2010, DOI: 10.4236/jemaa.2010.25039
Abstract: A Particle Swarm Optimization (PSO) based design of three-phase induction motors are proposed. The induction motor design is treated as a non-linear and multivariable constrained optimization problem. The annual material cost and the total annual cost of the motor are chosen as two different objective functions. The PSO is used to find a set of optimal design variables of the motor which are then used to predict performance indices and the objective functions. The proposed method is demonstrated for two sample motors, and it is compared with the genetic algorithm (GA) and the conventional design methods. The results show that the PSO-based method effectively solved the induction motor design problems and outperforms the other methods in both the solution quality and computation efficiency.

Journal of Applied Sciences , 2012,
Abstract: Studying of braking process in the Alternating Current (AC) motors has a great importance due to the need for reducing the braking and stopping time. In many applications, it may be necessary to use a three-phase induction motor on a single-phase supply system. The aims of this study are to investigate and discuss the behavior of a three-phase induction motor operating from single-phase supply when steady-state zero-sequence braking is used. Therefore, mathematical model was developed and the symmetrical components' method was used. To verify the obtained results, an experiment was performed and oscillograms of transient speed were recorded. Results show that the synchronous speed under braking has fallen to one-third of the motoring synchronous speed. And it was also observed that braking time can be controlled by changing the capacitance and rotor resistance values.
