AI Technical Summary
Technical Problem
Conventional submerged pumps using canned motors face efficiency losses due to wide gaps between the stator and rotor, increased manufacturing costs from requiring a casing, and risk of coating and impregnating resin degradation in anhydrous ammonia environments.
Method used
A manufacturing method for an immersion motor that directly immerses the stator and rotor in anhydrous ammonia, using polyethylene-based heat-sealing materials for coatings and impregnation, applied via powder coating methods to enhance corrosion resistance.
Benefits of technology
The method enables the motor to operate efficiently and prolongs lifespan by preventing resin degradation and improving corrosion resistance in anhydrous ammonia environments.

Abstract
The manufacturing method of an embodiment of an immersion motor is a manufacturing method of an immersion motor that is driven while immersed in anhydrous ammonia, and includes assembling a plurality of conducting wires that constitute a stator coil to a stator core, forming a first coating of a polyethylene-based heat-sealing material on the entire stator core to which the plurality of conducting wires are assembled using a powder coating method, assembling the rotor core to a rotor, forming a second coating of a polyethylene-based heat-sealing material on the entire rotor to which the rotor core is assembled using a powder coating method, and assembling the rotor with the second coating formed to the stator core with the first coating formed.
