The Malkus-Robbins dynamo with a nonlinear motor

Abstract

In a recent paper Moroz considered a simplified version of the
third class of self-exciting Faraday-disk dynamo model, introduced by Hide
, in the limit in which the Malkus-Robbins dynamo
results as a special case. In that study a linear series motor was incorporated
which led to an enriching of the range of possible behaviour that the
original Malkus-Robbins dynamo could support. In this paper, we replace the
linear motor by a nonlinear motor and consider the consequences on the dynamics
of the dynamo.
