Motor DC775 12V DC Electric Motors High Torque DC Motor Ball Bearing 6000RPM

The RS-775 DC motor is a high-performance brushed motor designed for demanding applications requiring high torque and stable output. It features a copper commutator set at the rear end, with a five-group winding configuration, ensuring enhanced electromagnetic efficiency and thermal stability.

The motor supports operation at 6V, 12V, or 24V DC, providing flexibility across a wide range of system designs. It is engineered for low acoustic noise and high torque output, making it particularly suitable for use in electric tools, small spindle drives, and DIY machinery.

The 775 designation refers to the standardized outer frame size of the motor housing, ensuring mechanical compatibility across multiple applications and mounting systems. The 12V variant offers a nominal speed of 4000 RPM under load, combining high-speed rotation with substantial torque performance.

This motor incorporates ball bearing support, contributing to reduced friction, extended service life, and improved load-handling capability. Key parameters such as operating voltage, rated current, shaft dimensions, gear assembly, and load characteristics can be custom-engineered to meet specific application requirements.

The RS-775 DC motor is widely adopted in applications requiring high power density, continuous duty operation, and compact form factor, such as:

• Cordless power tools
• Portable cutting/drilling equipment
• DIY automation projects
• Miniature mechanical spindles
• Robotics and motion control systems

Its robust design and high adaptability make it one of the most utilized brushed DC motor platforms in both industrial and consumer-grade applications.
