Abstract
Purpose
In order to keep the advantages of PM generators and eliminate its disadvantage – difficulty in regulating the magnetic field, hybrid excitation is an effective way. The purpose of this paper is to propose a novel way to achieve hybrid excitation by use of tooth harmonic field.
Design/methodology/approach
Unlike weakening the tooth harmonics field and EMF in traditional machines, in this paper the tooth harmonics field is proposed to form a novel hybrid excitation permanent magnet synchronous generator (HEPMSG).
Findings
The generation mechanism of tooth harmonic electromotive force (EMF) of rotor winding is introduced, and its influencing factors are discussed in detail. The matching design of tooth harmonic winding and field winding for maximum output field current of tooth harmonic excitation system is analyzed.
Practical implications
This machine can achieve not only effective adjustment of the air-gap magnetic field, but also elimination of the brushes and slip rings.

Abstract
Purpose
The purpose of this paper is to clarify the relationship between automated assembly and mass production environments such as the manufacture of cars, airplanes and white goods and methods of modelling and simulation. Even in this environment high‐level automated assembly is restricted to the original equipment manufacturers where production volumes are high and flexibility and the ability to quickly reconfigure systems are not major drivers. It proposes modelling of the fixing/assembly process and outlining why and how new methods are important throughout the manufacturing process. The paper aims to expand the domain of co operation of different research institutes, universities and companies.
Design/methodology/approach
The paper focuses on typically, fixture design, which involves the identification of clamp, locator, and support points, and the selection of corresponding fixture elements for their respective functions. In addition, the automation of fixture design activities in manufacturing is an important research area, which aims to achieve the integration of design and manufacturing. The most commonly used methods are pointed out.
Findings
The paper summarizes the main modelling and simulation methods applied to new fixing and assembly processes.
Research limitations/implications
Because of the chosen research approach, the paper is more general.
Practical implications
The paper includes implications for the development of a powerful new fixing method applied in the automotive and aerospace industry, which is important for stability and easy change in a rough manufacturing environment.
Originality/value
This paper fulfils an identified need to study how new fixing methods can improve motorcar and aerospace manufacturing.
