DC Generators
A DC generator is a device that converts mechanical energy into direct current electricity, playing a crucial role in various applications. Innotec Power stands out in this field by utilising permanent magnet alternators in all of its DC generators. These advanced units are more efficient than traditional induction alternators, offering significant benefits such as lower fuel consumption and reduced maintenance requirements.
The design of permanent magnet alternators not only enhances performance but also contributes to longer lifespan and reliability. Their compact size makes them easier to install and integrate into different systems, making them particularly ideal for mobile and remote applications where space may be limited.
Engine‑Mounted Generator Heads – Building Blocks for Your Best DC Generators
Our engine‑mounted generator heads are modular permanent‑magnet alternators designed to pair with the prime mover of your choice. They are the tools you use to build the best custom DC generator. Key features include:
- Fuel‑efficient design – proprietary permanent‑magnet technology reduces fuel use and electric ripple, maintaining peak efficiency above 93 %.
- Low maintenance – the bearingless DC‑PMG alternator eliminates slip rings, brushes, exciters and diodes. With no wear components, service intervals are extended and mean time between failures exceeds 80 000 hours.
- Compact & lightweight – the alternator’s reduced length and diameter make it about 30 % smaller than traditional units.
Flexible coupling – the design can bolt into virtually any engine housing and work with any manufacturer’s driveshaft.

How to Select the Right DC Generator
When choosing a dc generator system, it is important to match the power requirements with the right engine and alternator design. Here’s how:
Define your power requirement – Multiply the desired voltage by the current draw. For example, charging a 48 V battery bank at 50 A requires about 2.75 kW.
Choose a prime mover – Decide whether you need a diesel engine, turbine, or hybrid drive, and identify the most fuel-efficient RPM range.
Select rectification/control method –
Passive rectification: control generator voltage by adjusting engine speed.
Active rectification: allows a wider input range while maintaining stable output voltage.
Consider application and duty cycle – Decide whether the generator will run continuously or intermittently, and check environmental conditions such as temperature, humidity, and vibration.
