Product Description

The High-Torque 5*9*3 Motor, also known as the Compact Micro Motor 5x9x3, is a precision stepper motor model engineered for demanding industrial applications. Featuring a compact 5mm x 9mm x 3mm footprint, it delivers exceptional torque density while supporting direct integration with 2-4 external control modules via pulse/direction inputs. This stepper motor operates across a 5-24V DC range and withstands temperatures from -20°C to +85°C, ideal for robotics, automated manufacturing, and medical instrumentation. Its 1.8° step angle ensures ultra-precise positioning, with optional encoder feedback reducing step loss. The design includes a universal 4-pin interface compatible with CAN or RS485 protocols, though lacks onboard battery support. Key advantages include vibration damping, silent operation, and a 2-year service life, while potential thermal constraints require active cooling in continuous high-load scenarios. Detection distances reach 3mm via built-in Hall sensors. Limited to standard NEMA-8 mounting, this motor sacrifices modularity for space efficiency.
