Proportional actuators
Constant Torque - Force - over the stroke
MMT has developed a complete family of Linear and Rotary actuators providing a constant force (torque) and fast positioning on a limited linear or rotary stroke. The main features of these magnetic structures are:
- A constant force / torque over the displacement
- A reversed force / torque for a reversed current
- A force / torque directly proportional to the current
- Rotary displacement considered are less than 1 turn (360°)
- Linear displacement are between 1mm to 15 mm
- Very fast actuation time (40 ms for 80° stroke for example)
- A simple, robust and compact actuator structure
- Operational on a large temperature range : -40°C to +150°C
- Compatible with basic electronics
- Additional functions available on request
