Product Attributes
Product Description
The YPKK series high voltage three phase asynchronous motor, with frame size H355 to H1120, features a reasonable structure and advanced manufacturing technology. It offers high efficiency, energy saving, low noise, low vibration, reliable operation and convenient installation and maintenance.
The motor power, mounting dimensions and electrical performance comply with the national standard GB755-2000 "Rotating Electrical Machines Rating and Performance", relevant IEC standards and the industry standard JB/T10314.2-2002.
The motor is suitable for environments at an altitude of no more than 1000m, with ambient air temperature no higher than 40°C, and without serious dust, corrosive or explosive gases. Motors for hot and humid zones, plateau areas and other special working conditions can also be produced according to customer requirements.
The motor adopts a box-type structure. The frame is welded from steel plate, giving light weight and good rigidity. A closed air-to-air cooler is installed on the top of the motor, which is easy to dismantle and install, making maintenance more convenient. The stator uses an external pressure mounting structure. The stator windings are made with F-class insulating materials, and the winding ends are reliably fixed and bound. During manufacturing, the windings pass turn-to-turn impulse voltage tests and ground withstand voltage tests, and are treated with advanced vacuum pressure impregnation solvent-free paint VPI process. This provides excellent insulation performance, good mechanical strength and strong moisture resistance.
The squirrel cage rotor adopts a copper bar structure and is manufactured by reliable welding technology. It is verified by dynamic balancing, helping ensure smooth and stable operation. Rolling bearings or sliding bearings can be selected according to motor power and speed.
The motor can be used with frequency conversion speed control, with a speed control range of approximately 5 to 50Hz. Standard rated voltage is 6kV or 10kV, and protection level can be IP44, IP54 or IP55. Other voltage, frequency, protection level, cooling method and mounting requirements can be customized.
Packaging & Shipping
Standard seaworthy export packaging is used for long distance transportation. Plywood cases or fumigated wooden cases are available according to destination country requirements. Professional packing helps protect the motor, cooler and accessories during sea freight.
