Direct Drive Motor
Our direct drive motors deliver high torque as well as acceleration performance and high-precision control that are not possible with conventional speed reduction mechanisms. This makes them optimal for the manufacture of high-grade film.
Features/functionality
- Customizable high-torque, super low-speed motors
- Low noise, low maintenance thanks to gearless design
- Optimal for high-grade film manufacturing
These motors deliver a high torque/super low speed of about 8,000 Nm/20 min-1. We offer motors with the torque and rotating speeds that meet our customers’ demands.
