Abstract: | |||||||
This thesis presents a study of two outstanding problems
in eddy-current coupling theory:
(a) the steady-state performance of copper-faced
couplings.
(b) the transient performance of eddy-current
couplings.
After a general introductory chapter which reviews the
problems of coupling analysis and existing theories of the
machine, the work falls, broadly, into two parts.
The first part (chapters 2-4) presents a three-dimensional
theory of the copper-faced coupling and describes experiments
designed to test the validity of the theory.
The second part (chapters 5-9) is devoted to the transient
performance of eddy-current couplings; in particular, torque
response at constant slip speed. After reviewing existing
practice and possible theoretical approaches, a theory, based
on the transient solution of the diffusion equation, is developed.
Experiments on a new test machine, which investigate the
assumptions of the theory and the method of torque prediction,
are discussed in detail.
