CHS-GM12-10BY Mini Stepper Gear Motor

CHS-GM12-10BY Mini Stepper Gear Motor, DC 3.7-12V, 2-Phase 4-Wire with M4 55mm Screw Shaft

Product Overview

The CHS-GM12-10BY miniature stepper gear motor is a compact, high-precision 2-phase 4-wire motor designed for applications requiring controlled linear or rotational motion. It features a long M4 threaded screw shaft, metal gear reduction, and multiple gear ratios to suit various speed/torque needs.

Key Features

• Precision Stepper Control: 2-phase 4-wire bipolar drive with an 18° step angle, compatible with common stepper drivers (e.g., L6219) and PLC control systems for accurate positioning.
• Threaded Screw Output: 55mm long M4 standard threaded shaft, ideal for direct linear motion applications or custom mounting.
• Multiple Gear Ratios: Choose from 1:10, 1:30, 1:50, 1:100, or 1:298 to optimize speed and torque for your project.
• Durable Construction:
  • Pure copper windings for low resistance, high conductivity, and increased torque output.
  • Metal gear reducer for impact resistance, high precision, and low noise operation.
  • Compact dimensions (10×12×19.5mm, excluding shaft) and lightweight design (approx. 12g).
  
  
• Wide Voltage Range: Supports DC 3.7-12V operation (recommended driver current <150mA), making it versatile for different power setups.
