CHW-9L370 DC Worm Gear Motor, 5V 18RPM 131:1 Reduction, High Torque Turntable Motor with 9-Tooth Output Gear
Product Overview
The CHW-9L370 DC Worm Gear Turntable Motor is a high-torque, low-speed gear motor designed for turntables, display stands, and automation projects. It features a robust worm gear drive structure and a large modulus output gear, delivering reliable performance with built-in self-locking capability.
Key Features
- Worm Gear Drive: Copper worm paired with a POM worm gear reduces noise (≤45dB under standard conditions), improves wear resistance, and extends service life. The design also provides strong self-locking for stable positioning.
- High-Torque Output: With a reduction ratio of 131:1, it delivers a stall torque of ≥3.5 kg·cm at 5V, ideal for heavy-duty turntable applications.
- Durable Gear Structure: The 9-tooth, 2.0 modulus output gear enhances load capacity and wear resistance, ensuring reliable power transmission under high torque.
- Multiple Configurations: Choose from the standalone motor, motor with solderless plug-in wiring, motor with speed controller, or complete kit with power supply for plug-and-play convenience.
- Compact & Versatile: 61.5mm x 31.3mm dimensions, lightweight (approx. 125g), and a wide voltage range (3-24V customizable, standard 5V).
