RS775 DC Motor 12V 21000RPM High Speed Double Bearing Copper Motor

Experience industrial-grade power with the RS775 DC 12V High-Speed Motor. Unlike standard hobby motors, this “Double Bearing” edition is engineered for heavy-duty applications requiring extreme speed and torque. With a blistering top speed of 21,000 RPM, it is the ultimate choice for building DIY drills, table saws, CNC spindles, and lawnmowers.

Built with a pure copper coil and a built-in cooling fan, this motor maintains high efficiency even under load. The inclusion of dual ball bearings (front and rear) ensures smooth, vibration-free rotation and significantly extends the motor’s lifespan compared to cheaper bushing-based alternatives.

🚀 Key Features & Benefits

• Extreme Speed: Delivers up to 21,000 RPM at 12V, making it one of the fastest motors in the 775 class.

• Double Ball Bearing Design: Features ball bearings on both the front and rear shafts. This reduces friction, minimises noise, and prevents the shaft from “wobbling” under high lateral loads (crucial for cutting and drilling).

• High Torque: Generates substantial torque capable of driving drill bits, saw blades, and sanding discs without stalling easily.

• Pure Copper Windings: Ensures better conductivity, lower heat generation, and higher power efficiency.

• Self-Cooling: Equipped with an integrated cooling fan that forces air through the metal casing to regulate temperature during continuous operation.

Technical Specifications

Power Supply Guide (Important for Users)

This is a high-power motor. Standard 9V batteries or small 1A/2A wall adapters will not work.

• Minimum Requirement: Use a power supply rated for at least 12V 5A or higher.
• Recommended: A 12V 10A Switch Mode Power Supply (SMPS) or a high-discharge 3S LiPo battery is ideal to handle the startup current surge.

💡 Common Applications

• DIY Power Tools: Cordless drills, mini table saws, and chop saws.
• CNC Machines: Spindle motors for PCB milling and engraving.
• Robotics: Combat robots and high-speed rovers.
• Garden Tools: Electric lawnmowers and trimmers.
