Oswald Torque- and Direct Drives

Electric direct drives, so-called torque motors from Oswald, are permanent-magnet synchronous motors with torques of up to 450.000Nm.
These machines, adapted to customer requirements, offer very high torques in the smallest space thanks to their technology.

Due to the functional principle as well as the customer-specific adaptations to the engine enormous improvements on the customer machine can be achieved.
For example, energy consumption can be reduced and additional components such as gearboxes, belts or hydraulics can be saved.
The use of torque motors or direct drives in dynamic operation is just as worthwhile as it is at constant speeds.

Features of Oswald Motors

  • compact, robust, high power density
  • maintenance-free / low maintenance
  • low inertia, dynamic
  • long useful life
  • electrical calculation and developments according to customer requirements
  • diverse attachments according to customer requirements

Applications:
Press drives, shredders, winch drives, marine drives, mixers, servo hydraulics, hydropower, linear motors for forging machines, traction drives, etc.

We will be happy to adjust the electrical and mechanical design elements according to your requirements.
