Product Advantages
Permanent magnet synchronous motors offer unrivalled efficiency and high power factor compared to asynchronous motors. Depending on the original motor model, power rating, and load factor, energy savings range from 5% to 6–10%.
They maintain high efficiency and power factor across a load range of 25% to 120% of rated capacity.
The system achieves a power factor exceeding 0.98, significantly reducing grid current and lowering line losses by 2% to 4%.
Permanent magnet synchronous motors employ variable frequency drives, enabling load speed adjustment by altering operating frequency. This enhances operational efficiency and minimizes power losses, with variable frequency speed control achieving energy savings of 5% to 15%.
Applicable Scope
This series of products features frame sizes ranging from 100 to 355, with power ratings and mounting dimensions fully compliant with International Electrotechnical Commission (IEC) standards.
The motors employ F-class insulation, and frames H180 and above incorporate oil drainage devices.
Upon customer request, stator temperature monitoring can be provided. The operating mode is S1, the cooling method is IC411, and the enclosure protection rating is IP54.

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.
