Proportional actuators

Linear & rotary actuators for a constant torque force

illustration: Proportional actuators  

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
  • Easy integration of suspension spring/blades for vibrating designs
  •  Compatible with basic electronics
  •  Additional functions available on request
