3 axis nema23 200n.Cm(285oz.In)/3.0a stepper mot

This 3-axis NEMA23 stepper motor kit from Link Motor Industrial Co., Ltd. provides 200 N.cm (285 oz.in) of holding torque per motor at a 3.0A phase current, representing a 67 percent torque increase over lower-current variants in the same 57 mm frame size. The specific model referenced is 23H2A8430-01B, a bipolar hybrid design with 1.8 degree full-step resolution, supplied as a matched set of three motors for coordinated multi-axis motion systems. The higher current rating demands proportionally greater heat dissipation attention but enables direct drive of heavier inertial loads without mechanical reduction stages.

The 23H2A8430-01B designation follows common Chinese manufacturer numbering where '23' denotes NEMA23 frame, 'H2' indicates hybrid construction with two rotor stacks, and '84' typically corresponds to 84 mm body length (though this should be confirmed with the supplier). At 3.0A, resistive losses in the copper windings generate approximately 44 percent more heat than a 2.5A motor with equivalent winding resistance, making thermal management and driver current regulation accuracy more critical. Standard construction for this torque class includes N35 or N38 grade neodymium-iron-boron rotor magnets, 0.5 mm silicon steel laminations with insulating coating, and Class F insulation systems rated for 155 degrees C continuous winding temperature. The bipolar connection with four leads (or optional six-lead center-tapped configuration) permits full winding utilization for maximum torque density.

Engineers running higher-force CNC mills, direct-drive extruder mechanisms in filament deposition systems, or precision positioning tables with substantial payload mass will find the 200 N.cm rating suitable for applications where 120 N.cm motors would stall during acceleration. The kit format specifically targets machine builders who need synchronized axis performance from a single supplier source. Buyers must confirm with Link Motor Industrial Co., Ltd. whether the 3.0A figure represents the continuous thermal limit or a peak value, as driver setting errors that push continuous current beyond this threshold will accelerate insulation degradation. Also verify shaft geometry, connector pinouts, and whether the motors include integrated cables or require field termination.

Link Motor Industrial Co., Ltd. maintains its registered address at No.378 Hanjiang Road, Xinbei Zone, Changzhou 213022, Jiangsu Province, China, positioning it within the Changzhou National Hi-Tech District where precision motor manufacturing clusters have developed over two decades. The company's imported-tier supplier classification with harbor trust status indicates it has completed basic marketplace registration without verified on-site audit or sustained transaction history visible in this dataset. The zero percent response rate and zero recorded average response hours are identical to its sibling listing, reinforcing the need for direct communication channel testing before order commitment rather than reliance on platform-mediated metrics alone.

The product focus evident in this listing centers on higher-torque NEMA23 configurations for demanding automation applications, with the 23H2A8430-01B model suggesting a degree of product standardization and model numbering discipline. No information is disclosed regarding in-house versus outsourced manufacturing, winding automation levels, or raw material traceability systems. The supplier does not claim ISO 9001, ISO 14001, or IATF 16949 certification in the available profile, nor does it list export experience by destination market. Buyers evaluating this supplier against alternatives should request factory audit reports, sample test data including torque curves at multiple supply voltages, and references from existing OEM customers in comparable applications.
