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.
