Orange Planetary Gear DC Motor 12V 427 RPM 12.5 N-cm PG28M395-11.2K

The Orange Planetary Gear DC Motor PG28M395-11.2K is a compact, high-torque motor engineered for precision robotics, automation systems, and mechanical drive applications requiring controlled rotational force. This 12V DC motor delivers 427 RPM with exceptional torque output of 12.5 N-cm, making it ideal for professionals in robotics, industrial automation, and embedded systems who demand reliability and consistent performance. This motor solves the critical challenge of achieving high torque at low speeds while maintaining compact form factor, essential for space-constrained applications like robotic arms, conveyor systems, and automated machinery.

Product Overview

The PG28M395-11.2K features a planetary gearbox mechanism that multiplies motor torque through a series of precisely engineered gear stages. Unlike traditional spur gears, planetary gear systems distribute load across multiple gear teeth simultaneously, resulting in superior efficiency, reduced backlash, and extended operational lifespan. The 11.2:1 gear ratio converts the high-speed output of the DC motor into the specified 427 RPM with amplified torque, delivering 12.5 N-cm of holding and driving force. This configuration ensures smooth, quiet operation with minimal vibration, making it suitable for sensitive applications requiring precise motion control.

The motor's construction incorporates a robust brushed DC motor core with sealed planetary gearbox housing, providing protection against dust and minor moisture exposure. The 12V operating voltage makes it compatible with standard battery packs, power supplies, and automotive electrical systems, while the compact cylindrical design allows integration into tight mechanical assemblies. The motor shaft is precision-machined with standard mounting flanges, enabling straightforward coupling to load mechanisms without additional adapters.

How to Use

Connect the motor's positive and negative terminals directly to a 12V DC power source, ensuring polarity is correct to prevent damage. The motor will immediately begin rotating at approximately 427 RPM under no-load conditions. To control speed, integrate a PWM (Pulse Width Modulation) controller or variable voltage regulator between the power source and motor terminals. For load applications, mechanically couple the motor shaft to your mechanism using appropriate couplings or gear adapters. Always ensure the motor shaft rotates freely before applying load, and verify that the gearbox is properly sealed and undamaged.

When operating the motor continuously under maximum torque load, monitor temperature to ensure it does not exceed 60 degrees Celsius. If sustained high-torque operation is required, consider adding a small heatsink or allowing periodic cooling intervals. For applications requiring directional control, use a DPDT relay or H-bridge circuit to reverse polarity and change rotation direction. Always use appropriate circuit protection including fuses or circuit breakers rated for the motor's stall current of approximately 5-8 amperes at 12V.

Frequently Asked Questions

What is the difference between this planetary gear motor and a standard DC motor with external gearbox?

Planetary gear motors integrate the gearbox directly into the motor housing, eliminating separate coupling components and reducing overall assembly size by 40-50%. The planetary configuration provides superior load distribution across multiple gear teeth, resulting in lower backlash (typically under 5 degrees versus 10-15 degrees for spur gears), higher efficiency (85-90% versus 75-80%), and extended lifespan. This integrated design also reduces vibration and noise, making it ideal for precision robotics and sensitive applications.

Can I operate this motor at voltages other than 12V?

Operating the motor at voltages significantly different from 12V will damage the brushes and windings. However, you can safely operate at 10-14V using PWM controllers or variable voltage supplies for speed control. At 10V, output speed drops to approximately 356 RPM with proportionally reduced torque. Never exceed 14V as this will cause brush arcing and premature motor failure. For applications requiring different voltage levels, contact our technical team for alternative motor recommendations.

What is the maximum continuous torque and stall torque of this motor?

The rated continuous torque is 12.5 N-cm at 427 RPM under normal operating conditions. The motor can briefly deliver stall torque of approximately 18-20 N-cm when power is first applied or under sudden load conditions. However, stall conditions should not be maintained for more than 30 seconds as this generates excessive heat and can damage the motor windings. For applications requiring sustained high torque, ensure adequate cooling and consider using a larger motor model.

Is this motor suitable for outdoor or wet environments?

The sealed planetary gearbox housing provides protection against dust and light moisture, making it suitable for covered outdoor applications. However, it is not fully waterproof and should not be submerged or exposed to heavy rain or spray. For applications in wet environments, use appropriate weatherproof enclosures and ensure electrical connections are protected with waterproof connectors and insulation. For fully submersible applications, consult our technical team for specialized motor recommendations.
