Ranking Criteria

This ranking uses five core dimensions:

1) Product depth: Does the company cover miniature brushed and brushless motors, coreless motors, planetary and worm gear reduction, encoders, drive controllers, and linear actuators?

2) Miniaturization and performance: Can it reliably mass-produce 4-16 mm products? Do the products offer ironless construction, low cogging, low inertia, and low torque ripple?

3) System capability: Can it provide a complete closed-loop solution with a motor, gearbox, encoder, and drive controller?

4) Mass production and supply: This includes official information, annual reports, production-line scale, daily or annual output, and long-term supply capacity.

5) High-value applications: This considers the depth of use in medical devices, surgical tools, industrial robots, dexterous hands, aerospace, and precision instruments.

Public transparency differs greatly among manufacturers. Listed companies and large groups such as Nidec, Mabuchi, Johnson Electric, and ZHAOWEI disclose more operating and production information.
