MOTOX Helical Worm Geared Motors

The Cost-effective Angular Geared Motor

Helical worm geared motors are the favorably-priced solution for drives with angular geared motors. The efficiency is significantly better than that of pure worm geared motors due to the implementation as helical-worm geared motors. Due to the worm gear stage, high ratios can be implemented within small envelope dimensions. Further, helical worm geared motors represent an extremely quiet drive solution. Helical worm geared motors represent the most cost-effective solution for angular geared motors in the lower torque range.

MOTOX helical worm geared motors are available in the power range up to 11 kW and rated gear unit torques up to 1,590 Nm.

The geared motors are available in the following versions:

Foot or flange-mounting versions

Version with torque bracket

Solid or hollow shaft

Hollow shaft with key connection, shrunk-on disk, splines
