Hatz shows new fiPMG generator at EIMA

German engine specialist Hatz has presented its flywheel-integrated permanent magnet generator (fiPMG) at EIMA 2026.

This is a load-dependent generator used to recharge associated battery packs. Charging is triggered by the battery management system.

This translates to less noise, reduced emissions, less fuel expenditure (Hatz notes a reduction of around 40%) and reduced maintenance.

Applications include recharging of electric machines, small cranes and lighting towers.

The fiPMG is available with either the 1B50E (0.51 liters displacement) or 1B30E (0.34 liters) engine. Unlike a standard setup which would have the generator alongside the engine, the integrated flywheel adds almost no additional length to the unit.

With minimal overall change in the dimensions, integration can be completed with little additional engineering.

The fiPMG is also available as a Silent Pack version – this houses the unit in a box that further reduces noise emissions by about 10%.

All fiPMG models are both Stage 5 and Tier 4 Final emissions compliant across the full engine speed.

According to Hatz, the new fiPMG will enter series production in early 2027.
