Abstract

PURPOSE:To improve the dimensional accuracy of an underwater molded motor by molding the periphery of a coil end with unsaturated polyester resin and covering the outer periphery of a stator core with metal and unsaturated polyester resin, thereby eliminating a damage to the coil. CONSTITUTION:The outer periphery and the side of a stator core 2, to which a thin stainless steel can 3 is inserted into the inner periphery and the periphery of a stator coil end 5 are molded with resin molding member 4 made of unsaturated polyester resin, and the outer periphery of the member 4 is covered with an inner layer sheath 61 made of metal and a metal sheath 62 made of unsaturated polyester resin. In this manner, since the resin can be molded at low pressure and temperature, a damage of a coil can be eliminated, and the dimensional accuracy can be improved due to low shrinkability. Further, the sheath 61 can be prevented from corroding via the sheath 62.
