Our 57mm NEMA23 DC Stepper Motor is a high-performance 2-phase hybrid stepper motor, engineered for precision motion control in space-constrained industrial environments. With a standard 57×57 mm flange design, body lengths ranging from 41 mm to 112 mm, and optional 1.8° or 0.9° step angle configurations, this motor balances compact footprint with exceptional structural rigidity and thermal stability. Adopting open-loop control driven by pulse signals, it delivers reliable positioning without complex feedback systems, making it a versatile motion solution for industrial equipment manufacturers and system integrators.
The optimized 57×57 mm form factor fits seamlessly into equipment with tight mounting space, while maintaining high mechanical strength and heat dissipation performance, eliminating deformation or performance degradation under long-term continuous operation.
Built with precision-machined components and premium magnetic materials, the motor delivers a true standard step angle, supporting up to 256 microstepping for ultra-smooth motion and low vibration. It achieves positioning accuracy within ±0.05° and over 98% repeatable accuracy, meeting the strict requirements of high-end precision equipment.
With an optimized magnetic circuit and high-performance rare-earth magnets, this 2-phase hybrid stepper motor delivers holding torque ranging from 0.39 N·m to 3.1 N·m, outperforming comparable models by over 25% in torque output. It ensures smooth startup, consistent power transmission, and stable performance even under variable load conditions.
Designed for global industrial deployment, it operates reliably in an ambient temperature range of -20℃ to +50℃, with a maximum temperature rise of 80℃. It features 100MΩ minimum insulation resistance at 500VDC and 500VAC dielectric strength for 1 minute, ensuring long service life in harsh industrial settings.
This 57mm NEMA23 DC Stepper Motor is widely deployed across high-demand industrial sectors, including medical devices, optical measurement systems, CNC equipment, textile machinery, collaborative robots, industrial pumps, automated production lines, and smart home appliance manufacturing. Its balance of precision, compact size, and cost efficiency makes it ideal for both standard and custom motion control systems.
We offer comprehensive customization services to meet unique project requirements. Our engineering team supports tailored modifications including custom winding parameters, adjustable holding torque, matched encoders, gearboxes, and drive controllers, as well as custom lead length and connector configurations. We also provide full OEM support for mass production needs, ensuring consistent quality and alignment with your equipment design specifications.
Mount the motor via the standard NEMA23 flange, ensuring concentric alignment with the driven load to avoid radial or axial overload; maximum radial force is 75N (20mm from the flange), maximum axial force is 15N.
Connect the motor leads strictly according to the wiring diagram for your 4/6/8 lead configuration, ensuring correct phase matching to avoid loss of torque or motor damage.
Maintain shaft radial play within 0.02mm max and axial play within 0.08mm max during installation, and ensure adequate clearance around the motor for heat dissipation.
The standard sample MOQ is 3 units, with a standard lead time of 15 days; fast-track production is available for urgent project needs.
Yes, we offer full custom machining and configuration, including integration with encoders, gearboxes, and controllers, with dedicated technical support for your design needs.
First, validate compatibility between the motor and drive parameters, check for bearing fatigue or misalignment, and our technical team can provide targeted optimization solutions to minimize noise and downtime.
