Description
The RS-50 DC Geared Motor is a heavy-duty, industrial-grade actuator engineered for applications that demand exceptional torque, high durability, and prolonged operational cycles. Outperforming standard Johnson geared motors in both torque capacity and energy efficiency, the RS-50 is built to run continuously for hours under demanding loads. Featuring a robust 4500 RPM base motor paired with a precision metal reduction gearbox, it delivers incredible mechanical force while maintaining a lower current draw.
Operating smoothly across a voltage range of 6V to 15V DC (with a recommended 12V sweet spot), this specific variant delivers 30 RPM with a massive rated torque of 26 kg-cm and a full-stall load torque reaching an astonishing 125 kg-cm. The motor is equipped with an 8mm D-type shaft for secure, slip-free coupling with wheels, gears, or heavy-duty mechanical linkages. Whether you are building commercial floor-cleaning machines, automated industrial shutters, heavy robotic platforms, or custom DIY projects requiring immense power, the RS-50 provides uncompromising reliability and industrial-grade strength.
Note: This motor has a manufacturing tolerance of ±20% in RPM.
Key Features
- Monster Torque Output: Delivers a rated torque of 26 kg-cm with an immense full-stall load torque of up to 125 kg-cm for heavy-duty lifting and driving.
- High Efficiency & Durability: Consumes less current than comparable Johnson motors while offering superior longevity for continuous, multi-hour operation.
- Secure D-Type Shaft: Features a robust 8mm diameter, 21mm long D-cut shaft that prevents rotational slippage under high-stress loads.
- Industrial Gearbox Reduction: Combines a high-speed 4500 RPM base motor with a rugged reduction gearbox to translate high velocity into immense rotational force.
- Flexible Operating Voltage: Performs reliably across a 6V to 15V DC range, optimized for standard 12V power supplies and battery banks.
Benefits
- Extreme Load Handling: Easily manages high-resistance mechanical loads that would stall or damage standard hobbyist motors.
- Extended Operational Life: Engineered for industrial environments, ensuring reliable performance during long, continuous work cycles.
- Robust Mechanical Coupling: The 8mm D-shaft profile ensures your drive wheels or custom gears lock securely in place without requiring destructive set screws.
- Energy Efficient: Lower current draw (0.2A no-load / 1.2A full-load) preserves power source longevity in mobile and remote automated platforms.
- Versatile Professional Deployment: Trusted by engineers and makers alike for applications ranging from commercial cleaning equipment to heavy-duty robotics.
Applications
- Commercial Cleaning Equipment: The ideal choice for driving heavy brushes or drive wheels in floor-cleaning and scrubbing machines.
- Industrial Automation: Perfect for auto-shutters, welding machine wire feeds, heavy-duty actuators, and mechanical weighing machines.
- Heavy Robotic Platforms: Provides exceptional drive power and torque for large, all-terrain robotic vehicles and combat robots.
- Specialized Machinery: Widely used in peristaltic pumps, garbage disposers, grill rotisseries, and automated ticket/coin dispensers.
- Advanced DIY & Prototyping: A premier actuator for makers building high-torque custom machinery or mechanical art installations.
