INFINITY CNC Motor by ASG ULTIMATE

The INFINITY CNC motor is designed for maximum torque and reliable performance across spring tensions. It features a CNC-machined aluminum cap, stainless steel shaft, steel pinion gear, and a high-performance rotor with heat-resistant magnets. Thanks to carbon brushes and silver-plated wiring, it delivers excellent efficiency even under long-term use.
Unlike the BOOST series, this model has a full CNC aluminum housing and base for optimal heat dissipation. Ball bearings ensure smooth shaft stabilization and operation. Naturally, it comes with a CNC steel pinion gear and wear-resistant stainless shaft.

Key Features

  • Aluminum endbell – CNC-milled for precision and cooling.
  • Stainless steel shaft – twist- and wear-resistant.
  • Silver-plated wiring – better conductivity and reliability.
  • Ball bearings – for smooth operation and shaft stability.
  • Carbon brushes – longer life and minimal sparking.
  • Strong magnets – high torque and stable rotation.
