Technical Features:
1- Motor frame welded from premium-quality Q235B steel plates. Finite element modeling analysis applied to the motor structural and component design to ensure excellent rigidity and reliability. Low vibration and high-precision machining of rotating parts to ensure stator and rotor concentricity. Low noise, and frame stress relief technology ensures frame stability and dynamic performance.
2- Stator core laminations made of 0.5mm-thick, low-loss silicon steel sheets, with radial ventilation ducts separating the core segments.
3- Stator with windings insulated with mica tape entirely vacuum pressure imprenated (VPI) to ensure extremely reliable insulation and excellent temperature rise tolerance. Advanced technology for coil slot fixing and connection ensures long-term motor reliability.
4- Laminated pole core made of 1.5mm thick steel plates. Damping bars and damping rings made of premium-quality copper. Pole coils Class F insulated. Pole coils and damping rings soldered with brazing.
5- Premium-quality bearings to ensure long service life, easy maintenance, and excellent reliability.
6- Sensors and probes for coil & bearing temperature, vibration, cooling water leak detection, etc. to ensure effective real-time monitoring and safe running.
7- Options of brush and brushless excitation system:
* Static exciter are designed with slip rings and brushes that allow the current supply to reach the rotor poles by means of sliding contact. The direct current comes from an AC/DC static controller and converter located outside the motor. They are more often used in applications with variable speed with a frequency drive operation or in applications where the system dynamic response must be extremely fast.
* The brushless excitation system consists of an AC exciter and a rotating rectifier disk in an independent structure that rotate coaxially with the main motor that has higher reliability and is suitable for use in hazardous conditions by removing slipring-brush structure. The rotating rectifier disk is small and compact with the electrical connectors, structural fixings, and electrical heat sinks integrated and the petals insulated from each other to ensures reliable operation, low failure rate, and easy installation and maintenance. It uses technologies of automatic excitation, automatic removal of de-excitation resistors, and re-synchonization after pull-out, etc. to ensure reliable operation. The excitation cabinet adopts a fully digital circuit with high reliability and strong anti-interference. The main circuit control elements and air cooling system components have a low failure rate, ensuring long-term operation. Monitoring, disassembly, and maintenance are convenient with non-stop plug-in replacement and no debugging required after replacement.
