Driven by Thorlabs' Elliptec™ piezoelectric resonant motor technology, these linear stages are
available in kits that include a stage and interface board (Item # ELL10K(/M)). The imperial stage is
also offered as a standalone option (Item # ELL10). With a mass of 0.104 kg and maximum
dimensions of 102.3 mm x 67.0 mm x 15.3 mm (without the mounting bracket), the stage is lightweight
and compact. They are also designed for closed-loop operation, which allows the translating platform
be positioned with an accuracy of 50 µm and a repeatability of
±20 µm. When power is not applied to the motors, the stage is held
in place by an approximately 1 N combined force exerted by the
stationary arms of the motors. The assembled components of the
ELL10K are shown in the image to the right, with key features
labeled. The motor is highly dynamic and has no gearing. As the
motor includes no magnets, it is compatible with EM-sensitive
environments. Please see The Elliptec™ Motor tab for more

Thorlabs offers software for our Elliptec products capable of providing full and independent control of the stage. When the interface board is used as an accessory to change the position of the stage, its status in the software is automatically updated.

- Page 5 The electronics on the interface board convert the applied DC signal to a sinusoidal signal oscillating at the required resonance frequency. The ELL10K(/M) bundles include a 5 VDC power supply whose connector mates with the power socket on the interface board. Delivering power through this socket also leaves the Micro-B USB connector available to accept a USB cable connection to a computer, which can be used to control the stage remotely.
- Page 6 Operation of the Motors The motion of the ELL10 stage is controlled by forcing the piezoelectric elements to vibrate at specific ultrasonic frequencies. For each motor, there is an ultrasonic resonant frequency that will push the stage forward, and another that will pull the stage backward. Operating a motor at one of its resonance frequencies causes the tip of the motor to continuously cycle in a tight clockwise elliptical path.
