DC Generator for Military and Defence — High-Reliability PM Power for Field Applications
Military and defence power requirements share two characteristics that matter more than almost any other specification: reliability and reduced logistical burden. A generator that requires frequent service visits, carries consumable spare parts, or has wear-based failure modes creates logistical complexity in field environments where supply chains are constrained.
Innotec Power’s brushless permanent magnet DC generators address both requirements. The 80,000+ hour MTBF of our PM alternator design means no alternator-related failures within any reasonable operating schedule. The absence of brushes, slip rings, and exciters means no consumable parts to carry, no wear-based maintenance intervals, and no skill requirement for alternator service in the field.
Military Applications
Vehicle-Mounted Generator Heads
Engine-mounted PM generator heads for military vehicles requiring on-board DC power generation beyond the vehicle’s standard alternator capacity. Used for vehicle systems power, communications equipment charging, and weapon system auxiliary power. Available in 24V, 48V, and 96V to match vehicle electrical architecture.
Silent Watch / Quiet Operation
Hybrid military vehicle architectures allow the main engine to charge a battery bank while moving, then shut down the engine for silent observation or patrol operation. Our generator heads provide efficient battery charging during engine operation to maximise silent watch duration.
Field Power Units (APUs)
Compact DC generator sets for forward operating bases, command posts, and deployed field positions requiring reliable DC power without grid connection. Our 5 kW and 14 kW gensets are used in configurations from individual vehicle support to small base camp power.
Communications and Sensor Power
Remote sensor installations, communications repeaters, and surveillance equipment in austere environments use DC generator sets for primary or backup power where solar alone is insufficient.
Logistic and Support Vehicles
Recovery vehicles, field workshops, and engineering vehicles use DC generator heads for auxiliary power tool supply, welding equipment, and battery charging for fleet vehicles.

Reduced Logistical Footprint
The alternator is typically one of the highest-maintenance items in a conventional vehicle electrical system. Brush sets, voltage regulators, and diode packs are standard stocked items in military vehicle support units.
Innotec Power’s PM generator heads eliminate this logistical requirement entirely:
- No brush sets to stock — there are no brushes
- No slip ring service kits — there are no slip rings
- No exciter components — there is no exciter
- No diode pack replacement — internal rectification is sealed and non-serviceable
For a fleet of vehicles, eliminating these part numbers from the supply chain reduces stocked inventory, training requirements, and service time.
