Mechanical Resolution & Engineering Advantages
By coupling our stepper motors with precision-machined gearheads, we significantly improve the transmission efficiency and effective resolution at the output shaft. The theoretical step angle seen by the load is reduced proportionally to the reduction ratio, facilitating smoother motion profiles and higher holding torque.
Precision PM Series: Utilizing vacuum-impregnated porous bronze bushings, this series offers exceptional vibration damping and a nearly silent acoustic profile. It is the ideal choice for patient-proximal medical devices and high-end office automation where user comfort and thermal stability are critical.
Industrial NEMA Series: Leveraging high-grade gear materials and precision ball bearings, this series can achieve theoretical effective step angles as fine as 0.05°. These units maintain high structural integrity under significant radial loads, enabling ultra-precise motion control for high-dynamic industrial environments.
Kechen Motor ensures all geared assemblies are fully compliant with CE and RoHS standards. Customized gear ratios, shaft modifications, and integrated encoders are available to meet your unique engineering specifications.
