Balmar Hairpin Stator AT Series Alternators

Balmar’s newest AT-Series alternators are uniquely designed to deliver greater output and higher efficiency than OEM or traditional S-wound aftermarket alternators.

Equipped with the latest technology hairpin stators, 129 mm AT-12-165 and 139 mm AT-12- 200 series alternators deliver more output in a smaller frame size than any competitor’s small and mid-case alternators.

AT-Series alternators are designed for use with Balmar’s multi-stage Max Charge MC-614 voltage regulators, making it possible for these powerful alternators to provide targeted, customizable charging for a wide range of marine battery technologies. The densely-packed hairpin stator delivers exceedingly impressive low-end output and efficiency nearly 30 percent greater than comparable traditional wound designs.
