Abstract

DC60 (23/05/57) sealed compressor motor that can reduce leakage current caused by latent capacitance. Between the winding and the stator steel core, that is, a sealed compressor motor consists of the compressor and motor part that This motor's stator 7b is driven through a spindle inside a sealed container, with 23 stator iron cores 24 windings around the stator steel core and 32 insulating material between the steel cores. stator with winding This insulating material is made up of several sheets of thin insulation 32a, 32b overlapping. By several sheets of 32a one-side insulators, 32aa folds are formed at the two ends in the axial direction. And at this flap there is a tip in the axial direction of another 32b thin insulator sheet is inserted. The selected image is Figure 5.
