Abstract

Objectives: This article is aimed at providing a detailed design of a 250 W AC series motor. Analytical design of the motor is performed to determine the armature winding design, commutator diameter, magnetic circuit analysis. The motor is simulated to estimate its performance. Methods/Statistical Analysis: To estimate the performance of the motor, the motor is simulated and finite element analysis is implemented to determine the flux density, electromagnetic torque under different operating speeds. The results of magnetic circuit design and commutator design are used in the finite element method to simulate the motor accurate to practical conditions. Form the obtained results the losses are determined. Findings: The results obtained include the flux density plot and the electromagnetic torque for different speeds. From the obtained results the performance of the motor is evaluated and the losses are tabulated. Applications/Improvements: The motor is designed to run a washing machine. Other general applications of the motor are mixers, drilling machines, vacuum cleaners, water sprinklers.

Abstract

Background/Objectives: This paper deals with the design and implementation of Series Field Converter (SFC) for Doubly Salient Reluctance Motor (DSRM). Methods/Statistical Analysis: SFC is developed to reduce the total power loss by reducing the components. By including Resistive-Capacitive-Diode (RCD) snubber the losses are decreased and regenerative operation is provided. Findings: The RCD snubber is used to suppress the high voltage spike which occurs on the collector of the IGBT during turn ON and turn OFF period of the switch. Applications: The designed converter can be used for all types of reluctance motor.

Abstract

Day in, day out millions of people all around the world use public transportation systems. Within a metropolis, local rail transport is usually the only cheap and efficient way to get from one place to another. This is making new demands on the rail-bound mass transit. The door system needs to be robust, reliable, maintainable, safe and unaffected by the environment in order to guarantee an efficient train service. Because of round the clock operation of these trains, it is difficult to maintain the door systems regularly. They also get exposed to harsh environment like rain, sunlight and rough handling which may lead to malfunction. Safety is a very important constraint in any mass transit system and any malfunction in the door system can lead to severe mishap. Considering all the above constraints, we are proposing Linear Switched Reluctance Motor (LSRM) based door systems for railway carriages. The phase independent nature of LSRM makes it the best choice for door systems application as it can be made to operate even if any phase fails to work. This paper presents a clear design guide for a longitudinal flux single sided LSRM. The design parameters have been verified using two dimensional finite element analysis (2D-FEA). Finally a prototype has been built and tested. Test results imply the features of LSRM that make it a strong candidate for door systems of railway carriages.

Abstract

Background/Objectives: A steady increase in industrial applications has secured an important place for linear electric motors. This paper deals with the design, development and electromagnetic analysis of PMLSM for conveyor and transit applications. Methods/Statistical Analysis: PMLSM for the stated application has been designed and modelled. Electromagnetic analysis of the model has been done using 2D Finite Element Method (2D-FEM) to predict the performance of PMLSM. Findings: Electromagnetic characteristics of PMLSM have been investigated and results have been presented. Results show the upper hand of PMLSM over Linear Induction Motor (LIM) in terms of normal force to propulsion force ratio which is one of the primary concerns while choosing a linear drive for transit and conveyor applications after manufacturing costs. Applications: Some typical industrial applications of linear motors like PMLSM include electronic assembly, baggage handling, machine tools, PCB assembly/drilling, robotics, conveyors, elevators etc.
