Abstract

The invention provides a high-temperature-resistant winding, a manufacturing method thereof and a motor. The manufacturing method of the high-temperature-resistant winding comprises the following steps: a high-temperature-resistant conductor is wound into a coil; the conductor comprises a conductor and an insulating surface layer made of an inorganic insulating material; Placing the wound coil ina mold; Pouring slurry made of high-temperature-resistant inorganic insulating material into the mould, and solidifying the slurry and the coil into an integral structure; Opening the mold to obtain ahigh temperature resistant winding. As the high-temperature-resistant wire is wound into a coil, the insulate surface layer of the wire is made of an inorganic insulate material, so that the coil canwithstand a high-temperature environment of more than 300 DEG C; The inorganic insulating material is used for potting and solidifying the coil, which plays the role of fixing and protecting the coil, and enhances the effect of bearing current and force of the winding manufactured in the high temperature environment above 300 DEG C. The limit that existing motors and electrical appliances using polymer organic materials fpr insulation and temperature resistance are difficult to be above 300 DEG C is broken through.

Description

Technical field [0001] The invention belongs to the field of motors, and more specifically, relates to a method for manufacturing high temperature resistant windings, high temperature resistant windings manufactured using the method, a motor using the high temperature resistant windings, and an electrical appliance using the high temperature resistant windings. Background technique [0002] The current motor temperature resistance grades are Y, A, E, B, F, H, C, and the corresponding maximum operating temperatures are 90℃, 105℃, 120℃, 130℃, 155℃, 180℃, and above 180℃. , A total of seven levels. Generally speaking, the higher the temperature resistance of the motor, the greater the unit mass power of the motor and the better the overall performance. The temperature resistance of the motor is mainly determined by the temperature resistance of the insulating material used. At present, most motors use polymer organic materials as motor insulation materials. Only a few polymer materi...
