AEG drive revolution
Dark Matter™ is the new generation of brushless motors for demanding players and service technicians. The absence of brushes and commutator means higher efficiency, silence, lower power consumption and longer life of the entire drive system.
Brushless vs. brushless - differences you can feel
- No friction → no brushes = less heat, less noise, longer life.
- Higher efficiency → longer playing time on the same battery.
- Better trigger response → high TPA and instant start.
- Lower component load → smoother gears and bearings, stability over long runs.
- Maintenance → no brush replacement or commutator sparking.
Key features of Dark Matter™ 27k (Long)
High torque
Stable operation with strong springs(up to M190) while maintaining a smooth cycle.
Trigger response
High TPA and instant start - ideal for S-AEG and precision semi-automatic.
Quiet running culture
Noticeably quieter than classic brush motors - greater comfort and less vibration.
CNC housing
CNC-milled aluminium - rigidity, robustness and effective heat dissipation.
Energy efficiency
Lower current consumption and less strain on the battery compared to brushed counterparts.
Longer service life
Fewer wearing parts → less maintenance and stable performance over time.
