AT-Series and the New XT-Series Alternators from Balmar bring together the latest innovations in alternator design to deliver incredible charging power in a compact, Marine-friendly package.

The New XT-Series Alternator family features a state-of-the-art, braided stator wire design to generate exceptional output in the smallest possible area. The XT-Series produces slightly more power than our previous AT-Series 165A design and operates 5o-10oC cooler.  In addition, we’ve added Balmar’s Smart Ready® internal regulator technology to provide an additional level of fault tolerance for cruising boaters.  Available XT-Series mounting styles have also expanded to include the “Vortec” 9Si design found on many GM gasoline engines.

The AT-Series 220A Alternator family features a hairpin-wound stator design which uses densely wound square copper wire to generate up to 220A at 3,000 engine rpm.   Hairpin-wound stators feature 96 slots – compared to 36 slots in a traditional S-wound stator – allowing the hairpin-wound stator to develop superior electromagnetic energy and efficiency to other traditional stator designs.
