Module assembles directly to board-mounted camera, accepts a standard threaded lens, operates on 3.3V and accepts high-level digital motion commands
Article in Design News – Dramatic reductions in voltage and power requirements are making tiny piezo motors and drive systems an interesting option for portable, low-power medical devices. By eliminating the need for the high voltage normally associated with piezo systems, a new piezo motor design from New Scale Technologies enables miniature motion systems that operate on a single 3-V battery without using voltage boost circuits.
The closed-loop actuator module incorporates piezoelectric micro motors and control electronics (drive ICs, position sensor and microprocessor) in a one-inch-cubed volume. The actuator system generates no magnetic fields, and can therefore be located in close proximity to navigation systems that use the earth’s magnetic field to measure orientation and roll rate.
Intelligent Automation has demonstrated a fully functional prototype.
New Scale Technologies’ M3 (Micro-Mechatronic Module) Design Platform enables rapid development of custom closed-loop micro actuator modules, building on the company’s miniature SQUIGGLE motor and TRACKER position sensor technology.
The “Reduced Voltage” SQL-RV-1.8-6-12 piezo micro motor and NSD-2101 drive chip deliver performance comparable to much larger motion control systems, at 40% lower power and less than one-fourth the size
