The RS-555 DC Motor is a high-power, versatile motor designed for applications requiring both speed and torque. It features an internal cooling fan and a robust carbon brush construction, allowing it to handle sustained loads without burning out. This is the standard motor used in DIY PCB drilling rigs because its 3.17mm shaft is perfectly compatible with most mini-drill chucks and collets.
High Torque Output: Strong enough to drive small cutting tools, fans, and high-traction wheels.
Dual Ball Bearings (Optional/Variant): Often features a front ball bearing for smoother rotation and longer life.
Internal Cooling: Built-in fan blades help dissipate heat during continuous operation.
Standard Shaft Size: The 3.17mm (1/8) shaft fits a wide variety of pulleys, gears, and drill chucks available in the market.
Wide Voltage Range: Runs safely from 5V (for low speed) up to 24V (for maximum power).
