MOTOX Helical Geared Motors

The Conventional Solution for Your Drive Application

Helical geared motors are the conventional solution for your drive application. Helical gear units are coaxial units where the gear unit output shaft is in-line with the motor shaft. A solid shaft is always used as output shaft. Additional components – e.g. gear wheels or chain wheels – to transfer the force to the driven load are therefore required. Solutions utilizing helical geared motors are capable of an extreme variable speed range. In many cases, helical geared motors represent the most cost-effective solution for your drive task.

MOTOX helical geared motors are available for the power range up to 200 kW and rated gear unit torques up to 20,000 Nm. These geared motors are available in the following versions:

Foot and flange-mounting versions
