Product Advantages
Optimized Electromagnetic Design
Finite element analysis has beenapplied to evaluate electromagnetic performance, heating, mechanical stress,and deformation, followed by an optimized electromagnetic design. A thorough optimization of dimensions, air gap, slot fit,and slot shape has been carried out,resulting in appropriately matched motor dimensions and optimal performance.
Low Harmonic Windings
The use of low harmonic windings reduces stator copper loss and stray losses, leading to enhanced operational efficiency of the motor.
High-Strength Magnetic Slot Wedges
The use of high-strength magnetic slot wedges, stable slot wedges, as well as fastening processes and materials successfully resolves the issue of magnetic slot wedge detachment, leading to enhanced electrical performance of the motor.
Optimized Ventilation and Cooling System
The use of backward-curved centrifugalfans and axial flow fans optimizes the internal and external ventilation systems of the motor. This improves the cooling effect, reduces ventilation losses(especially in high-speed motors), lowers ventilation noise，and enhances motor efficiency.
Insulation System
This series of motors uses an insulation system whose performance has been significantly enhanced in every respect. Tests of voltage characteristics, temperature characteristics, bending strength, breakdown voltage, thermal ageing and electrical ageing all show that the system has reached first-rate level. High-quality mica tape and environmentally friendly impregnating resin are employed, and every stage of coil manufacture—winding, expanding and taping—is completed on CNC machines. The final VPI treatment guarantees reliable insulation, superior mechanical strength and excellent moisture resistance.
High Efficiency
This series of motors reduces losses by 20% compared to the efficiency outlined in JB/T 10446 and GB/T 13957. They comply with the Grade-2 energy efficiency requirements specified in GB30254-2013, making them truly high-efficiency motors. These motors cansignificantly boost customer operational efficiency compared to products with Grade-3 energy efficiency,
Applicable Scope
This series of motors is widely used to drive general-purpose machinery such as compressors, fans, water pumps, machine tools, conveyors and other mechanical equipment. Serving as the prime mover in mining, machinery, petrochemical and power-generation industries, they reliably drive high-inertia loads including blowers, coal mills, rolling mills, hoists, crushers and belt conveyors.

OUR PRODUCT
Distributed Phase-Shifting Machine
With the implementation of the new GB 38755-2019 Guidelines for Security and Stability of Power Systems, requirements for short-circuit capacity and inertial support at new-energy stations have risen sharply. Distributed synchronous condensers are thus set to become standard equipment at such stations. High-capacity synchronous condensers offer outstanding reactive-power compensation; their sub-transient characteristics keep the internal voltage practically constant during faults, allowing them to absorb or inject large amounts of reactive power instantaneously and thereby safeguard grid operation. In particular, as the country vigorously expands its new-energy power sector, the deployment of distributed synchronous condensers can effectively counteract current surges, frequency deviations, voltage fluctuations and flicker—mitigating the inherent volatility and intermittency of renewable-energy sources.

Flywheel Energy Storage System
Flywheel energy storage constitutes a physical energy storage method, harnessing the kinetic energy inherent in a rotating body to store and release electrical energy. This conversion between kinetic and electrical energy is achieved via an electric motor/generator coaxially mounted with the flywheel assembly. When operating as a motor, the drive unit accelerates the flywheel rotor, converting input electrical energy into stored kinetic energy. When operating as a generator, the drive unit decelerates the flywheel rotor, converting stored kinetic energy back into electrical energy for output. The acceleration and deceleration of the drive unit are controlled by a dedicated control unit.
