CHW4058-42 Worm Gear Stepper Motor 2-Phase 4-Wire, 3-24V DC, 1:17/1:36/1:54 Ratio, with Bracket & Pulse Driver Options

Product Description


Meet the Chihai CHW4058-42 Worm Gear Stepper Motor, a high-torque 2-phase 4-wire stepper motor designed for precision positioning in demanding automation projects. With a rugged worm gear design, it delivers exceptional holding torque (up to 50 kg·cm with reduction) and zero-backlash performance, making it ideal for camera sliders, smart home devices, and 3D printers.

Available in multiple reduction ratios (1:17, 1:36, 1:54, and custom ratios starting at 5 units), this motor lets you fine-tune speed and torque for your project. Choose from standalone motor, motor + mounting bracket, motor + pulse driver, or a full kit for plug-and-play integration. The 8mm D-shaped shaft (customizable) and compact 42×42×106mm body fit tight spaces, while the wide 3-24V input range ensures compatibility with most stepper drivers.

Key Features & Benefits


✅ High Torque Worm Gear Design: 3.5 kg·cm base holding torque (up to 50 kg·cm with reduction) for heavy-load applications.

✅ Precision Control: 1.8° step angle (down to 0.00345° with high reduction ratios) for ultra-fine positioning.

✅ Flexible Configuration: Choose reduction ratios, mounting brackets, and pulse drivers to match your project needs.

✅ Wide Voltage Compatibility: Works with 3-24V DC, compatible with most 2-phase 4-wire stepper motor drivers.

✅ Durable Build: Insulation Class B (130°C) and robust construction for long-term use in automation setups.

Notes :

Important Safety & Usage Warning:

  • The motor's maximum allowable torque is 50 kg·cm. Do not operate it above this value.
  • Do NOT subject the motor to repeated stalling, as this can cause permanent damage to the gears and motor windings.
