Overview
The Compumotor M57-51-R13 is a servo amplifier and motor drive from Parker Compumotor’s M57 series. It provides digitally-controlled proportioning for precise motor control in motion-critical applications. This unit combines hybrid permanent magnet stepper motor technology with a 20 kHz bi-polar chopper power amplifier to deliver stable torque output across variable speeds.
Key Features
- Digital current proportioning for smooth torque delivery at low speeds
