300N, vacuum compatible linear actuator

LTC300 delivers nanometer resolution with load capacity of 300 N with a 20 mm stroke

Acuvi Piezo LEGS LTC 300 Linear Actuator

Heavy duty linear actuator with nanometer precision

  • True linear direct drive
  • Vacuum compatible
  • Resolution down to sub-nanometer
  • 300 N force
  • 20 mm stroke
  • Self-locking
  • No backlash

True direct linear drive

The drive technology is direct, meaning no gears or lead screws are needed to create linear motion. The motor moves by microstepping, dividing a full waveform-step into nanometer size increments. Speed ranges from nanometers per second to millimeters per second, and can be seamlessly controlled in the whole dynamic range with no need to alter the driving mode.

The twin concept makes for high force output in a compact body, in this case a stall force of 300N. This gives a more robust design without the need of ball bearings.

It has direct drive with no backlash and can microstep in the sub-nano millimeter range. Designed for vacuum environments

Full force greater then 300 Newton power-off locking safety function inherent to the design.

Main dimensions LTC300

Motor performance LTC300

Motor performance with waveform Rhomb (filled) and waveform Delta (dotted). The full step length is the average distance the drive rod moves when the legs take one full step (i.e. for one waveform cycle).

Note: A standard deviation σ of 0.5 μm should be taken into account.
Typical values are given for 20ºC.

Controlling the motor

Our motor control units come in many different versions, with controllers and amplifiers for laboratory use as well as for integration into OEM devices.

We can also license the drivers for customers that want to build their own driver electronics.

LTC300 LEGS® Piezo Motor Starter Kit

Starter kits are available for the LTC300. Starter Kits are for evaluation purposes only with a max quantity of 3 kits/customer. You only pay for the motor.
