Aerotech Inc.Request Info
PITTSBURGH, Dec. 18, 2013 — Aerotech Inc.’s Npaq 6U high-power drive rack provides up to 30 A for brush, brushless or stepper motors, and its plug-in amplifiers support both linear and pulse-width-modulation (PWM) topologies.

Featuring high-performance, double-precision digital signal processors (DSPs), the system performs current- and servo-loop closures digitally, enabling loop-closure rates up to 20 kHz. It handles digital and analog I/O processing, data collection, laser firing and encoder multiplication tasks in real time.

Standard options include integrated encoder multiplication, per-axis brake control logic, I/O expansion and integrated emergency stop circuitry. The device contains two configurable power supply sections rated at 600 W each to support a variety of motors with different operating voltages.

A dedicated Ethernet port communicates with third-party I/O modules for increased I/O count applications.

stepper motor
A positioning drive that rotates a fraction of a 360° turn when the motor coils are activated, resulting in linear or rotary motion. They are generally one of two types, either variable reluctance or permanent magnet; the characteristics are much the same. Also called stepping motors.
