Technology and benefits

The absence of brushes and a commutator reduces components subject to wear, lowering routine maintenance requirements. Compared with conventional brushed motors, brushless technology provides quieter operation and improved energy efficiency, reducing the load on the battery.

High torque contributes to a more responsive drivetrain, while the CNC-machined aluminium housing provides a robust structure and helps dissipate heat.

Compatibility and installation

This motor is intended for electric AEG replicas requiring a long-shaft motor. Before installation, check the replica's mechanical configuration and compatibility with any existing ETU or MOSFET electronics.
