WERNA 6.5KW / 8.1kVA three-phase brushless synchronous alternator designed for generator sets operating at 1500rpm. This industrial-grade alternator features H-class insulation and meets international certification standards including CE and ISO9001.

• Permanent magnetic generators providing invariable excitation under all operating conditions
• Easy connection with power networks or other generators
• Standard 2/3 pitch windings minimize excessive midline current
• Balanced rotor with single or two sealed ball bearings
• Convenient maintenance access to terminals, rotating diodes, and coupling bolts
• Wide range of flange adaptors and single bearing coupling discs
• 100% copper winding wire for optimal conductivity and efficiency
• Two-time vacuum impregnation dipping for enhanced insulation protection

Standard IP22 protection rating with optional IP23 enclosure available for enhanced environmental protection.

All alternator rotors undergo precision balance testing with vibration levels below BS6861 P.1,G 2.5 standards.

Three-field alternator with 12 leads connected to terminals in the terminal box, located on the non-drive end with removable panels for easy access.

H-class insulation with special materials and proprietary immersion technology for superior protection in corrosive environments.

2/3 pitch winding design effectively eliminates third harmonic waves (3rd, 9th, 15th), making it ideal for UPS applications with nonlinear loads.

Each unit undergoes comprehensive testing including 4+ hours of commissioning, idle load testing, full load testing, 10% overload testing, noise level measurement, and control panel verification.

Compliant with GB755, BS 5000 Part 3, VDE 0530, NEMA MG1-22, IEC34, CSA C22.2-100, and ASB59 international standards.
