Axial-field electrical machines offer an alternative to the conventional machines. In the axial-field machine, the air gap flux is axial in direction and the active current carrying conductors are radially positioned. This paper presents the design characteristics, special features, manufacturing aspects and potential applications for axial-field electrical machines. The experimental from several prototypes, including d.c. machines, synchronous machines and single-phase machines are given. The special features of the axial-field machine, such a ....etc

ABSTRACT



Because of high requirements in power, efficiency, installation space and weight, the design of electrical machines for hybrid electrical vehicles is a particular challenge. This seminar describes a comparative study allowing the selection of the most appropriate electric-propulsion system for a parallel hybrid electric vehicle (HEV). This seminar is based on an exhaustive review of the state of the art and on an effective comparison of the performances of the four main electric propulsion systems, namely the d ....etc

Electrical Machines (EE256)
1. What is the function of carbon brush used in D.C generator?
The function of carbon brush is to collect current from the commutator and supply is to the external load circuit and to the field circuit.
2. Distinguish between lap winding and wave winding used in dc machine
 Lap winding is designed for high current and low voltage machines.
 Wave winding is designed for low current and high voltages.
3. Write the number of parallel paths in a lap and wave connected win ....etc

INTRODUCTION
This paper provides an introduction to automation. Automation is the use of control systems and information technologies reducing the need for human intervention. In the scope of industrialization, automation is a step beyond mechanization. Then it provides the applications of automation in industries such as manufacturing, agricultural, health care, distribution and logistics, cold storage, retail, field service, government. Automation (including roboticizati ....etc

3-Phase Induction MotorsIntroduction
• 3-phase induction motors
are simple, low cost,
and easy to maintain.
• They run at essentially
constant speed from
zero-to-full load.
• Therefore, they are the
motors most frequently
encountered in industry.
