Custom SQ-100 SQUIGGLE Micro Motors

High-force custom piezo motors for research, test and manufacturing

Custom SQ-100 Series micro motors offer higher resolution and push force than the smaller SQL Series motors, and have travel ranges to 50 mm. These patented piezoelectric motors are used for nanopositioning in the research lab, in semiconductor testing, and in manufacturing. They offer:

 

  • High resolution (20 nm)
  • Long travel (to 50 mm)
  • Fast, quiet and smooth motion
  • Self-locking operation for “set and hold” positioning
  • Vacuum and ultrahigh vacuum versions available with ultra-low outgassing and heating
  • Non-magnetic version available

 

Custom SQ-100 motors drive axial loads of greater than 5 Newtons with 20 nm resolution. Like all SQUIGGLE motors, they generate no magnetic fields in operation and hold position with the power off.

 

We also create vacuum (10-7 Torr) and ultrahigh vacuum (10-10 Torr) versions for in-vacuum alignment without mechanical feed-throughs.

SQ-2300 Motor Controller

The SQ-2300 bench top controller operates one custom SQ-100 Series motor. The controller operates on DC power from an AC wall plug transformer (provided). Each SQ-100 SQUIGGLE motor has a “smart” connector that stores its optimum drive parameters including frequency, phase and voltage. These parameters are downloaded to the SQ-2300 drive electronics when the motor is connected.

 

Connect the SQ-2300 to your PC to control the motor using the New Scale Pathway™ software (included), or use the optional SQ-2310 handset (sold separately).

 

New Scale Pathway Software

New Scale Pathway™ Software enables easy PC/Windows-based control of the SQUIGGLE motor using the SQ-2300 controller. The easy-to-use, "point and click" graphical user interface lets you operate the motor by entering values in boxes (speed, step, frequency, etc.) and clicking graphical buttons (jog, run, etc.). It also features a powerful script generator that enables you to create and run automated commands and sequences for almost any motion control task. The script editor is fast, flexible and easy to use, even by non-programmers.
