DC motor A22C-29

6 Vcorelessfor power tools

Overview
Coreless motors A22C series (outer diameter φ22 mm). The series includes multiple sub-models covering different lengths, voltages and performance ranges suitable for precision instruments and mechanical tools. Some sub-models are commonly used in surveying instruments and high-pressure nailers (notably A22C-12 and A22C-24).
