RS-550VC DC Motor – Direct replacement for power drills and screwdrivers, ready to install
Has your motor burnt out, lost its speed, or are you looking for more power for your RC project? The RS-550VC DC motor is the ideal solution, requiring no modifications. It is a direct drop-in replacement for the original motor in most 9V–12V power tools and comes with the pinion gear pre-installed — simply swap it out and you’re ready to go.
Note: This product is sold as a single unit (1 piece). Please verify the compatibility of the 12-tooth pinion (8.6 mm outer diameter) with your equipment’s gearbox before ordering.
Why choose this model? (Key benefits):
- 60W power in a 37.2 mm diameter body — genuine power for drilling into dense wood or thin metal without taking up extra space compared to your original motor.
- Up to 25,000 RPM — provides instant throttle response, perfect for both workshop screwdrivers and high-speed RC models.
- Compatible with 9V, 10.8V, and 12V — works seamlessly with standard Li-Ion battery packs and most popular power tool brands.
- Factory-fitted 12-tooth pinion — no need to buy parts separately or hunt for the right size; it is already attached.
- Standard 550-series dimensions — the 25 mm mounting hole spacing and 75.1 mm length ensure a direct fit without the need for custom adapters.
- 5.5A starting current — controlled startup even under heavy load, preventing power spikes that stress your battery.
Details and Performance
The 550 series is the de facto standard for portable power tools, and the RS-550VC adheres to these specifications with precision. The 3.2 mm diameter shaft (12.5 mm length) holds the included pinion securely, while the 37.2 mm housing fits perfectly into the motor cavity of most 9V–12V drills and screwdrivers.
With 25,000 RPM and 60W of rated power, this motor is also well-suited for more demanding applications: DIY robotics, miniature ventilation systems, or RC models where speed is essential. The 5.5A starting current is engineered to manage resistive loads during startup without overloading your power supply circuit.

Frequently Asked Questions
Will this fit directly into my 12V screwdriver?
In most cases, yes. The RS-550VC is designed as a direct replacement for the RS-550 series. Please ensure the 12-tooth pinion (8.6 mm diameter) and the 25 mm mounting hole spacing match your specific tool.
Can I power it with less than 9V?
This is not recommended. Below 9V, the RPM drops significantly and the carbon brushes may wear out faster. The minimum operating voltage is 9V.
Is it suitable for RC projects or DIY robots?
Yes. The high speed of up to 25,000 RPM and the compact size make it ideal for RC models, robotics, and any 9V–12V project where you need a balance of speed and power in a small form factor.
How many units are included in an order?
One motor per order. If you require more, please adjust the quantity in your basket before checking out.
Do I need to buy the pinion separately?
No. The motor comes with the 12-tooth pinion already mounted on the shaft (8.6 mm outer diameter, 5.2 mm thickness). It is compatible with standard gearboxes found in RS-550 series tools.
