yrkk (seat number 1000) series large high-voltage three-phase asynchronous motor has reasonable structure and advanced technology. it has the advantages of high efficiency, energy saving, low noise, low vibration, reliable operation and convenient installation and maintenance.
the motor adopts box structure. the frame is welded with steel plate, light weight and good stiffness. the closed air/air cooler is installed on the top of the motor, which is convenient to disassemble and assemble, and is conducive to the maintenance and repair of the motor. the sliding ring cover has an observation window for observing the operation.
the stator is equipped with external pressure structure, the stator winding is insulated with f-class insulation material, and the end of the stator is fixed and bound reliably. during the manufacturing process, the stator has undergone many turn-to-turn pulse voltage tests and ground voltage withstanding tests, and has been treated with advanced vacuum pressure impregnating solvent-free paint equipment and technology (vpi) abroad. therefore, the insulation performance of the motor is excellent and reliable, the mechanical strength is good, and the moisture-proof ability is strong.
the winding rotor is made of f-class insulation material. motors can be used to drive various kinds of machinery, such as large crushers, cutting machines, transport machinery and other mechanical equipment.
