25GA370 12V 1000RPM Gear Motor | Metal Gearbox DC Motor for Robotics Projects
Disclaimer: This gear motor is designed for DC operation at 12V. Do not exceed rated voltage. Always use appropriate motor drivers (e.g., L298N, L9110S, MOSFET H-bridge). Avoid short circuits and ensure proper heat dissipation if running continuously.
25GA370 12V 1000RPM gear motor
The 25GA370 is a robust, compact DC gear motor designed for applications that require a balance of speed and torque in a small footprint. Combining a 370-series DC motor with a precision metal gearbox, this unit delivers consistent rotation and durability. It is a preferred choice for small-scale robotics, automated mechanisms, and DIY engineering projects. With a no-load speed of approximately 1000 RPM at 12V, it is well-suited for fast-moving robots, conveyor rollers, and high-speed turntables.

Final note: Shaft loading – avoid excessive radial or axial force on the output shaft to prevent premature gearbox wear. Always mount the motor securely; for permanent installations, consider using thread-locker on the mounting screws. When driving this motor with transistors, relays, or H-bridges, install a flyback diode (e.g., 1N4007 or 1N5819) across the motor terminals to protect your electronics from voltage spikes. Do not stall the motor for extended periods – this can overheat the windings and damage the gearbox.
