SKU: 65107
Availability: InStock

Description

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.
