Submersible motors require efficient cooling solutions for optimal performance, durability, and energy efficiency. This article explores the four main cooling methods used in submersible motor technology.
The closed-loop cooling system uses the latest technology. It ensures high performance in both dry and wet installations, where the motor is not fully submerged.
A key strength of closed-loop cooling is that it is not sensitive to impurities in the pumped media. The closed-loop ensures the coolant is never contaminated. The pump can also berun at lower speeds compared to other cooling types.
Direct cooling is a simple and cost-effective solution that relies on the pumped liquid to cool the motor. It is ideal for installations where the motor is submerged during operation.
Media cooling involves circulating a portion of the pumped liquid inside a cooling jacket surrounding the stator housing. This method is suitable for both dry installations and wet installations where the motor is not sufficiently submerged.
External cooling is a complex solution for high-temperature applications where liquid temperatures exceed 40°C for extended periods. An external water supply is connected to a cooling jacket surrounding the stator housing, and access to clean water is required whenever the pump is running. External cooling is required to maintain the motor’s full power rating in warm-liquid applications.
