Aerotech BA20-40 Servo Drive Amplifier

The Aerotech BA20-40 Servo Drive Amplifier is a single‑axis, linear servo amplifier designed to drive servo motors in precision motion systems. It delivers ±40 VDC to the motor and can supply up to 20 A peak current, enabling strong torque during rapid moves or load transients. The unit arrives as a complete modular package with a heatsink and metal cover, and includes a bus power supply that operates from 200–240 VAC, simplifying integration into lab or production environments. As part of Aerotech’s BA amplifier family, the BA20-40 supports closed‑loop servo control via Aerotech control interfaces, offering accurate position, velocity, and torque performance for demanding applications. It is suitable for driving both brushless servo motors and brushed DC servos, making it well suited for precision positioning stages, automation platforms, and robotics where reliable single‑axis drive performance is required.
