NMB PG Permanent-Magnet Stepping Motors with Gearboxes

NMB PG permanent-magnet geared stepping motors combine a PM rotor motor with a reduction gearbox for compact OEM motion mechanisms. The range includes miniature K-series configurations and several larger J, D and C arrangements. These PM products are distinct from the PG20 and PG25 hybrid geared families, even though their names share the PG letters.

Applications and Industries
Manufacturer application examples include appliance mechanisms, printer or office-automation motion and related compact OEM drives. Select the exact PM geared configuration by output torque-speed duty, travel scale, reversal behavior and mechanical integration.

Review Summary
Consider the PM geared range when a compact low-speed output and a defined reduction ratio fit a valve, appliance or adjustment mechanism. Keep the complete motor-and-gearhead identity, torque units and ratio in the specification. Large reduction and a small nominal output step do not establish zero backlash, high accuracy or safe load holding.
