Propulsive unit ELEPSY50
The propulsive unit ELEPSY50 is based on the collector-free synchronous electric motor on permanent magnets. Unlike traditional bow-thrusters, the propulsive unit unites the electric motor with blades of the rowing screw. From there all shafts, bearings, gaskets, gear wheels, couplings, transfers and lubricants are removed. Only the electromagnetic field is used.
It is proved that banding of a permanent magnet and the prop is possible. This design has better hydrodynamic characteristics, than the ordinary bow maneuvering device.
