ABSTRACT:
An electric motor for wholly sealed compressors using, as a coolant, HFC-134a and using, as a refrigerator oil, a polyalkylene glycol oil, a polyol ester oil or a polyvinyl ether oil, and having a structure in which the free conductors are firmly secured and insulated with an insulating material which is chemically stable and has excellent insulating property. A plurality of free conductors are insulted from and secured to each other with an epoxy resin and, preferably, with a powdery epoxy resin. The powdery epoxy resin is particularly effective in insulating the coil ends of the electric motor for sealed compressors provided with a stator in which a coil wound on the stator core is constituted by a plurality of conductor segments, and the ends (coil ends) of the conductor segments protruding beyond the core are joined to each other to form the coil.
