Abstract: We describe a low-mode dynamo model. This model implements the various known regimes of cosmic dynamo systems, in particular, the various regimes of reversals. The source of regular reversals in the model is its internal dynamics. Violation of this cyclicality, transition to the chaotic regime of reversals are caused by fluctuations of the parameters, that are interpreted as the result of spontaneous coherent addition of the higher modes. The simplicity of the model allows you to easily modify it for various celestial bodies.

Keywords: dynamo models, reversals.
