Abstract

A marine propulsion unit with a slip-ring cooling system and a contra rotating motor having an inner rotor and an outer rotor, comprises a slip-ring housing and a slip-ring assembly arranged within the slip-ring housing, wherein the slip-ring assembly comprises at least one slip-ring element being in contact to the outer rotor. The marine propulsion unit further comprises an air channel arrangement comprising a first position being connected to the slip-ring housing and a second position. An air fan device is configured to generate a cooling airflow that flows from the first position to the second position of the air channel arrangement creating a negative pressure within the slip-ring housing and an outflow filter unit arranged at the second position of the air channel arrangement for filtering the cooling airflow exiting the air channel arrangement.
