Controllers suit linear motors

The MC-3000 and MC-1000HR controllers generate ultrasonic-frequency electronic signals to drive Squiggle motors.

New Scale Technologies has released two new motor controllers for its miniature piezoelectric Squiggle motors.

Both offer on-board electronics for closed-loop control of the company's linear motors.

The miniature controllers are suitable for Squiggle motor evaluation, for integration into OEM instruments, and for use as reference designs for OEM systems.

The MC-3000 and MC-1000HR controllers generate ultrasonic-frequency electronic signals to drive Squiggle motors.

Both controllers accept position feedback from commercially available analogue or digital position sensors, allowing complete closed-loop control of Squiggle motors.

Users can easily control motor direction and speed (from um to mm/s), move to a target position, move a specified distance, and numerous other functions.

Squiggle motor position resolution as small as 20nm.

Closed-loop position resolution is determined by the resolution of the position sensor and A/D convertor.

The controllers ship with New Scale's motor control software for easy evaluation of Squiggle motors via the Windows PC user interface.

An ActiveX control is included, and may be integrated into other applications written in languages such as C++ or Visual Basic.

The controllers can also accept ASCII commands or input from an optional manual handset.

Documentation describes the low-level ASCII control codes that an embedded system or microcontroller would send to a motor control chip.

The new MC-3000 motor controller drives the tiny SQL-1.5 Squiggle motor, the world's smallest linear motor.

Each MC-3000 controller runs two motors in open-loop or closed-loop configuration.

The MC-1000HR motor controller is a high-resolution version of the original MC-1000 controller for SQL-3.4 and SQ-100 series linear Squiggle motors.

Each controller runs one motor in open-loop or closed-loop configuration.

Evaluation kits include a Squiggle motor, motor controller, control software, AC power adapter and cables.
