PROBLEM TO BE SOLVED: To provide a liquefied dimethyl ether dipped type motor which operates long-term in liquefied dimethyl ether. SOLUTION: This liquefied dimethyl ether dipped type motor provided with a plurality of slots in an iron core is mounted with a coil and an insulation spacer in the slot, and is formed by dipping the motor in which the coils are fixed by driving a wedge in an opening portion of the slot in the liquefied dimethyl ether. The resin or its complex where the lowering of a bending elastic modulus after dipping in the liquefied dimethyl ether for a predetermined time is≤5 %, are used as a wedge material and an insulation spacer material, therefore each elastic modulus of the wedge and the insulation spacer does not lower even after long driving, and the coil is not loosened, thus providing the liquefied dimethyl ether dipped type motor having long insulation life.
