Product Advantages
Optimized Electromagnetic Design
Finite element analysis has beenapplied to evaluate electromagneticperformance, heating, mechanical stress,and deformation, followed by an optimizedelectromagnetic design. A thoroughoptimization of dimensions, air gap, slot fit,and slot shape has been carried out,resulting in appropriately matched motordimensions and optimal performance.
Low Harmonic Windings
The use of low harmonic windingsreduces stator copper loss and stray losses,leading to enhanced operational efficiencyof the motor.
High-Strength MagneticSlot Wedges
The use of high-strength magnetic slotwedges,stable slot wedges, as well asfastening processes and materials successfullyresolves the issue of magnetic slot wedgedetachment,leading to enhanced electricalperformance of the motor.
Optimized Ventilationand Cooling System
The use of backward-curved centrifugalfans and axial flow fans optimizes the interna!and external ventilation systems of the motor.This improves the cooling effect, reducesventilation losses(especially in high-speedmotors),lowers ventilation noise，andenhances motor efficiency.
Insulation System
This series of motors employs aninsulation system with significantlyenhanced performance in every aspectThe tests on voltage characteristicstemperature characteristics, bendingstrength,breakdown voltage, thermaaging, and electrical aging all indicate thatthe insulation system has reached a first-rate level.

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.
