Product Description

The three-stage planetary structure achieves a larger reduction ratio through series stages, suitable where speed is low and torque is high.

It balances torque output with compact size and is often used in small drives that require fine motion control.

Craftsmanship · Details Matter

Care in every detail — each process is strictly controlled for factory-grade quality.

Motor Housing

Motor Housing

The housing is stamped from galvanized steel sheet for high strength and stable, reliable performance.

Pure Copper Coil

Pure Copper Coil

Copper wire delivers stronger conductivity and lower heat build-up, cutting energy loss so the motor keeps putting out power.

Motor Rear Cover
