Helical Geared Motors – Compact and Powerful Drive Units for Industrial Use
Helical geared motors are integrated drive systems that combine a helical gearbox with an electric motor, offering an efficient and compact solution for applications requiring reliable torque transmission and precise motion control. Due to their high efficiency, low noise level, and flexible mounting options, helical geared motors are a standard choice in many industries. In this article, you’ll learn how they work, where they are used, and why Rehfuss Drive Solutions is the ideal supplier for tailored helical geared motor systems.
What is a Helical Geared Motor?
A helical geared motor is a fully integrated drive unit consisting of:
A helical gear unit for torque multiplication and speed reduction
An electric motor (usually AC or servo) directly mounted to the gearbox
A solid output shaft, typically arranged in parallel with the motor shaft
This design ensures space-saving installation, smooth operation, and high mechanical efficiency, even in demanding continuous-duty applications.
How Does a Helical Geared Motor Work?
The electric motor generates a high-speed rotation, which enters the helical gearbox. The angled teeth of the helical gears mesh gradually and distribute the load smoothly, reducing speed and increasing torque. The output shaft delivers the torque directly to the driven machinery.
Helical geared motors are available with different gear ratios, torque ratings, and mounting configurations to meet various performance and space requirements.
Benefits of Helical Geared Motors
1. High Efficiency
Thanks to the optimized meshing of helical gears, efficiencies of up to 98% are achievable – minimizing energy loss.
2. Quiet and Smooth Operation
The gradual engagement of gear teeth reduces vibration and operating noise, making them suitable for noise-sensitive environments.
3. Compact and Space-Saving
Integrated motor and gearbox in a single housing saves space and simplifies installation.
4. Robust Torque Output
Helical geared motors offer high torque density and are capable of continuous operation under load.
5. Flexible Installation
Foot-mounted, flange-mounted, or shaft-mounted configurations are available to suit every machine layout.
6. Ready for Automation
Available with encoder feedback, brake systems, and connectivity for variable speed drives and PLCs.
