Product Description
The Ypkk series high voltage three phase asynchronous motors with frame size H355 to H1120 are designed with a reasonable structure and advanced manufacturing technology. They offer high efficiency, energy saving performance, low noise, low vibration, reliable operation and convenient installation and maintenance.
The power rating, mounting dimensions and electrical performance of the motors follow the national standard GB755 2000 Rotating Motor Rating and Performance as well as relevant IEC standards and industry standard JB T10314.2 2002.
These motors are suitable for environments at an altitude of no more than 1000m above sea level with ambient air temperature no higher than 40°C and without serious dust corrosive or explosive gases. They can also be produced for hot humid zones plateau areas and other special working conditions according to customer requirements.
The motor adopts a box type structure. The frame is welded from steel plate, providing light weight and good rigidity. A closed air to air cooler is installed on the top of the motor, making dismantling, installation, maintenance and repair easier.
The stator uses an external pressure mounting structure. The stator windings are made of F class insulating materials, with reliably fixed and tied end sections. During production, the windings pass repeated turn to turn impulse voltage tests and withstand voltage tests to ground, and are treated with advanced vacuum pressure impregnation solvent free paint VPI equipment and process. This gives the motor excellent insulation performance, good mechanical strength and strong moisture resistance.
The squirrel cage rotor uses a copper bar structure and is produced with advanced reliable welding technology. It is verified by dynamic balancing to ensure smooth and dependable operation.
Rolling bearings or sliding bearings can be selected according to motor power and speed. The motor supports frequency conversion speed control with a speed control range of 5 to 50Hz. The rated voltage is usually 6kV or 10kV and the protection level can be IP44 IP54 or IP55. Other voltage frequency protection levels and technical requirements can also be provided according to customer needs.

Quality Control
All measuring apparatus and instruments are calibrated every year. Quality control is carried out for each key component and production stage.
Test
Each motor must be tested before leaving the factory. Only qualified motors can be shipped, and each motor is provided with a test report.
Routine test items include winding three phase DC resistance, winding insulation resistance to ground, winding withstand voltage test, no load current, no load power, no load loss, three phase no load current imbalance, locked rotor current, locked rotor torque, maximum torque, rotation direction, horizontal vibration, vertical vibration, axial vibration and noise.
Type test items include full load input power, full load current, stator winding loss, rotor winding loss, iron loss, mechanical loss, other losses, full load slip ratio, stator winding temperature rise, bearing temperature, thermal winding insulation resistance, overload test, full load power factor and efficiency.
After Sales Service
Standard warranty is 12 months after commissioning or 18 months after delivery, whichever comes first. Extended warranty can be discussed according to project requirements.
