Abstract
An ammonia-resistant motor used for a closed-type refrigerating compressor comprising a stator and a rotor; during work, the stator and the rotor of the motor are immersed in the ammonia refrigerant; the winding, the slot wedge and the slot insulation are locked through self-lock fasteners, thereby preventing them from moving in the slot; the self-lock fasteners are fluorine plastic fasteners; the end portion of the motor winding is wound with a layer or multi-layers of fluorine plastic tape, and the outer layer of the fluorine plastic tape is provided with a binding tube; the binding tube is made from fluorine plastic, and the tensile strength of the binding tube is greater than that of the fluorine plastic tape.
