PROBLEM TO BE SOLVED: To provide a high efficiency stator of an electric motor to be built in a totally-enclosed compressor with HFC enclosed inside as a refrigerant and to provide a low cost electric motor eventually. SOLUTION: In the slot of the stator of the electric motor built in the totally- enclosed compressor with HFC enclosed inside as a refrigerant the bobbin is partitioned as integrated fabrication, the winding as concentrated winding via the bobbin is prepared at the teeth of the stator, the dispersion-proof insulation cover to prevent the concentrated winding, draw-out wire and connectors from dispersing, and the fixture is partitioned to fasten and unify the bobbin with the dispersion-proof insulation cover. The dispersion-proof insulation cover is facilitated with the fixing method to ensure fastening the ventilation hole for the refrigerant with the draw-out wire, where the material of the bobbin and dispersion-proof insulation cover is of super-engineering plastic. All these specifications now develop the electric motor, high in efficiency and low in manufacturing cost.
