Core Technology Analysis: What is the YJTKK Series?

YJTKK Xima Electric MotorIt is not merely a simple model designation; it representsXi'an Simo Motor在High-voltage frequency conversionthree-phase asynchronous motorThe pinnacle of innovation in the field. Here, “Y” denotes asynchronous motors, “J” signifies compact structure, “T” represents variable frequency speed control, and “KK” indicates air-to-air cooling (IC611).

This motor is specifically designed for applications requiring precise speed regulation. Compared to ordinaryHigh voltage motorsUnlike conventional systems, it can integrate with variable frequency drives to achieve smooth, stepless speed regulation across a wide frequency range. This enables the equipment to “allocate power on demand” according to actual load requirements, eliminating the significant energy waste previously caused by regulating flow through valves or dampers.

Why Choose Xima YJTKK Motors?

Among numerous motor brands,YJTKK Xima Electric MotorThe company's significant market share is primarily attributable to several core breakthroughs in its design and manufacturing processes:

1. Exceptional energy-saving performanceFor fan and pump loads, energy savings from variable frequency speed control typically reach 20% to 50%. Xima Motors has optimized electromagnetic design to reduce high-order harmonic losses, enabling the motor to maintain high efficiency even during low-speed operation.High efficiency and low temperature rise。



2. The insulation system is robust and durable.Considering the impact of variable-frequency power supplies on insulation systems, this series of motors employs a specialized insulation structure and advancedVPI Vacuum Pressure Impregnation ProcessThis not only enhances electrical strength but also improves moisture and corrosion resistance, ensuring the motor's long-term stable operation even in harsh environments.
3. Heat Dissipation and Noise ControlThe unique box-type structure combined with an efficient air-to-air cooler enables a more scientifically optimized heat dissipation path for the motor. Simultaneously, fluid dynamics optimization of the airflow design significantly reduces operational noise, meeting the environmental standards of modern green factories.

Case Study: Induced Draft Fan Retrofit Project at a Thermal Power Plant

To provide a more intuitive demonstrationYJTKK Xima Electric MotorTo illustrate the application value, we take the induced draft fan retrofit project at a large thermal power plant as an example. The plant originally used outdated fixed-speed motors, relying on adjusting damper openings to control airflow. This approach resulted in significant throttling losses and large inrush currents during startup, causing substantial impact on the power grid.

• Smooth startAchieves true soft start functionality, reducing starting current from 5-7 times the rated current to approximately 1 times the rated current, significantly extending the service life of mechanical equipment.
• Energy Efficiency EnhancementDuring low-load operation, the motor speed automatically reduces, achieving a measured comprehensive energy savings rate of 35.1%.
• Automated IntegrationThe motor seamlessly integrates with the DCS system, enabling closed-loop automatic control of airflow and reducing errors caused by manual intervention.

Selection Recommendations and Considerations

AlthoughYJTKK Xima Electric MotorOutstanding performance, but the following points should still be considered during selection to ensure the right fit:

• Define load characteristicsIt is necessary to confirm whether the load is constant torque (e.g., belt conveyors) or variable torque (e.g., fans and pumps), as different loads impose distinct fundamental frequency design requirements on the motor.
• Cooling method matchingAlthough the YJTKK standard configuration features air-to-air cooling, if the installation environment is confined or the ambient temperature is excessively high, water cooling or other customized solutions may need to be considered.
• Variable Frequency Drive MatchingEnsure that motor parameters are matched with inverter parameters (particularly regarding voltage reflection issues during long cable operation). Install output reactors or filters as necessary.
