One of the most important things that you should look at is an engine and alternator coupling. The coupling techniques include direct drive (close or open coupled), as well as gearbox drive and pulley system.

When you are looking to select the type of engine and alternator coupling to use, your system engineer will consider all aspects of the application. The system engineer would consult with the manufacturer will then consider the following design features, to ensure engine-alternator drive

 system compatibility:

Suitability of the prime mover to support the alternator’s rotor mass.

Suitable flywheel housing design in terms of stiffness and rigidity with the engine cylinder block.

Torsional analysis of the Generating Set to ensure engine/alternator compatibility is achieved.

Suitable Generating Set mechanical support scheme in terms of base-frame design and carefully considered AVM locations.

Meeting the SAE International Standards 

The Society of Automotive Engineers (SAE) standard is often used as a guide by the industry to define the dimensions of the adaptors and couplings. This particular method of sizing for adaptors and couplings has been adopted by the manufacturing industry as a standard. SAE designs specify the dimensions - diameter, length, width, and tolerance. These are used for engine flywheel housings and the mating transmission housing flanges. Typical dimensions used on alternators range from SAE 00 to SAE 6 (adaptor sizes). On the other hand, typical dimensions for the coupling discs used on alternators range from SAE 24 to SAE 6.5. You need to adhere to SAE designs so to ensures consistency in the product and system configuration, especially when interfacing with other standard-compliant equipment. The correct SAE arrangement for a Generating Set is always determined by the prime mover.

So, get in touch with a professional distributor to get the compliant engine and alternator coupling in UAE. Get help from the leaders and ensure that you get the right solutions for your needs.
