DC Cradle Motor | High-Torque Electronic Swing Actuator ⚙️👶

The WRK-370SD-10655 is a specialized brushed DC motor engineered for high-durability applications, most commonly used as the primary drive unit in automatic baby cradles and electronic swing systems. This motor is designed to provide consistent, low-speed oscillating power while maintaining the quiet operation necessary for nursery environments.

Key Performance Features

• Optimized Torque Profile: Specifically wound to handle the rhythmic weight distribution of a rocking cradle, ensuring smooth motion without stuttering.

• Precision Carbon Brushes: Equipped with high-grade internal brushes that extend the operational lifespan and reduce electrical noise during long sessions of continuous use.

• Balanced Output Shaft: Features a hardened steel shaft designed to interface perfectly with the eccentric cams or gear assemblies typically found in cradle drive-trains.

• EMI Suppression: Designed to minimize electromagnetic interference, ensuring that the motor does not disrupt nearby electronic baby monitors or nursery sensors.

• Ventilated Metal Casing: The rugged steel housing includes strategically placed ventilation holes to dissipate heat efficiently, preventing thermal cut-off during overnight operation.

Technical Specifications

• Motor Type: 370-Series Brushed DC.

• Housing: Zinc-plated anti-corrosive steel.

• Terminals: Solder-tab connectors with a dedicated red-dot polarity indicator for correct rotational direction.

• Mounting: Features dual M3 threaded mounting holes on the front face for secure chassis attachment.

Typical Applications

• Electronic Baby Cradles: The primary motor for automatic rocking and swaying mechanisms.

• Automated Displays: Used in point-of-sale moving displays that require consistent, long-term rotation.

• Smart Home Gadgets: Powering automatic curtain drawers or small-scale oscillating devices.

• DIY Robotics: A reliable choice for rovers or mechanical arms requiring a 370-class motor footprint.

Top 3 Customer Questions & Concerns 🙋‍♂️

⚙️ What is the input voltage for this motor? The 370SD series typically operates between DC 6V and 12V. For cradle applications, it is often paired with a 9V or 12V power adapter to provide the necessary torque for the swaying motion.

🔌 How do I ensure it rotates in the right direction? Check the rear of the motor for a small red dot near one of the solder terminals. Connecting the positive wire to this marked terminal will result in a standard clockwise rotation.

⚠️ Can I use this with a speed controller? Yes. To adjust the rocking speed of a cradle, this motor is fully compatible with DC PWM (Pulse Width Modulation) controllers, allowing for a gentle start and custom speed settings.
