Description
The SPG30E-20K DC Geared Motor with Encoder is a popular, cost-effective compact brushed DC motor solution from Cytron Technologies, engineered specifically for medium-sized rovers, omni-drive robots, and automated mechanisms. Featuring an integrated 5V quadrature Hall-effect encoder, this motor provides both position and direction sensing via two out-of-phase output channels (placed 90° apart). This advanced telemetry allows you to monitor shaft rotation and regulate motor speed with high precision.
Housed in a sturdy cylindrical gearbox with a 20:1 reduction ratio, this 12V motor delivers a reliable 1.2 kg-cm of torque at 185 RPM. It features a convenient 6mm diameter D-shaped output shaft (15.5 mm length) for secure, slip-free coupling. Imported directly from Cytron, every unit is rigorously bench-tested for performance reliability. Note: Due to warehouse performance verification, the physical label on the motor may display ratings that slightly differ from standard manufacturer specifications.
Mounting Caution: The mounting thread depth of this motor is 3.2 mm. Ensure you use M3 screws of appropriate length (factoring in the thickness of any mounting brackets) to avoid damaging the internal gearbox.
Note: Product images are for reference only. The actual product may vary slightly in appearance or dimensions. Connector cables are not included with this motor.
