Optical and RF Tuning
Tiny closed-loop modules provide high-precision motion for
adaptive tuning, filtering, focusing and more
Field-deployable and mobile tuning systems require smaller
actuators that use very low power, yet offer high precision and
accuracy as well as long travel. For fiber communications and RF
transmission systems, the demand for smaller size comes from the
need to pack more capability into smaller boxes – whether to satisfy
consumer preference for compact in-home devices, or the need for
higher densities in outdoor instruments.
New Scale provides compact, high-precision motion solutions for this
market. Based on our patented piezoelectric motor and related
technology, our miniature closed-loop motion modules provide
unmatched position resolution and accuracy. Unlike traditional
motors, the modules do not generate magnetic fields while moving. Their compact size and
low power use make them ideal for field-deployable and portable
systems.
M3-L Linear Actuator Modules
M3-L micro-mechatronic modules are customizable, fully integrated,
closed-loop actuators.
- Size approximately 27.5 x 13.0 x 7.5 mm
- Resolution 0.5 µm
- Accuracy better than +/-25 µm
- Stroke 6 mm or more
The M3-L module is based on New Scale’s M3 design platform. This
platform incorporates a piezoelectric SQUIGGLE micro motor,
motor drive ASIC, position sensor and microprocessor. The modules
accept high-level digital commands via standard serial interface
(I2C or SPI). No external control board is necessary.
M3-L modules have low power consumption and maintain position during power-off. They use a 3.3 V input for
battery-powered operation.
M3-L modules have smaller size, higher resolution, and lower
power use than traditional stepper motors. They can be rapidly customized to OEM
specifications including mounting and load interface, dimensions, and
push and/or pull operation.
Figure 1 shows a block diagram for the M3-L module. The SQUIGGLE motor moves
a mechanical assembly which is designed to fit the application. The
TRACKER NSE-5310 position sensor detects the movement of a multi-pole magnetic
strip attached to the moving mechanical assembly, and provides the direct digital
position information to the motion control processor. The NSD motor
drive ASIC accepts commands from the processor and drives the motor.
System input is provided as high-level commands from the system microprocessor via standard I2C or SPI serial interface. The
M3-L operates on standard 3.3 V battery power.
