STAMFORD® PERMANENT MAGNET ALTERNATOR

Generating Power through Variable Speed Cummins Generator Technologies have used their expertise in generator design and manufacture to bring you a new generation of axial flux bearing-free STAMFORD Permanent Magnet Alternators (PMA). Advantages of this development include a substantially smaller footprint by replacing the engine flywheel, high efficiency and use in either fixed or variable speed applications up to 4000 RPM. Working in conjunction with the STAMFORD Power Conditioning System (PCS) the packager can produce a full variable speed generating set to deliver high quality output power in a very compact package, providing benefits of significantly reduced overall size, weight and fuel consumption.

FEATURES Substantial mass and volume reduction High efficiency No bearing Integrated flywheel replacement Compact modular design Independent self regulated 3 phase output Can operate as a motor or a generator High Power / Weight / Torque ratio High Short circuit handling capability Can be used for "Drive Through" applications. APPLICATIONS Military Telecom Marine Mobile Refrigeration Vehicle mounted mobile power
