The Malkus-robbins dynamo with a Linear Series Motor

In a recent paper Moroz [2003] considered a simplified version of third class self-exciting Faradaydisk dynamo model, introduced by Hide [1997], in the limit in which leads to the Malkus–Robbins dynamo [Malkus, 1972; Robbins, 1977] as a special case. In that study a linear series motor was incorporated which led to an enriching range of possible behavior 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.
