Abstract

The invention concerns a propulsion system for small and medium sized boats, of the type that provides a bank of storage batteries (10) for an electric motor (40) suitably connected to a propulsion screw (50). According to the invention, the said electric motor (40) is an asynchronous motor of the squirrel-cage type and, between the said electric motor (40) and the said bank of storage batteries (10), a static converter (30) is inserted, which is capable of generating a mainly sinusoidal voltage for the said asynchronous motor, with variable voltage and frequency. According to the invention the ratio between the said voltage and said frequency is maintained constant (figure 5).
