Abstract

Compact electric compressors/motors, especially compressors/motors used for subsea applications, need cooling systems to provide good efficiency and durability. Such cooling systems consist of pump, pressure compensator, separate external cooler and piping. This system cools down the electric motor. Referring to this, the reduction of costs and components is a common known aim in the present development.

Motor Cooling in Housing Wrapper by Holes within Seawater

Idea: Jan Slotman, NL-Hengelo

Compact electric compressors/motors, especially compressors/motors used for subsea applications, need cooling systems to provide good efficiency and durability. Such cooling systems consist of pump, pressure compensator, separate external cooler and piping. This system cools down the electric motor. Referring to this, the reduction of costs and components is a common known aim in the present development.

The following proposed cooling system of electric motors allows a direct cooling of the medium in which the compressor is in (see Figure 1). The medium flows through holes and pipes and cools the housing.

The proposed solution has the main advantage that some components of cooling systems may be unnecessary, e.g. pump, accumulator cooler and external piping.
