The Aerotech BA20-160 is a high-performance servo amplifier for precise DC motor control in industrial automation and robotics. It drives both brush and brushless DC motors with self-commutation via Hall effect feedback, delivering peak currents to 20 A and continuous output at 10 A across a 24–160 VDC bus. The amplifier combines transformer isolation between control and power stages with opto-isolated drive and feedback signals, ensuring reliable operation in electrically demanding environments. An integral 5 VDC, 250 mA auxiliary supply powers encoders and Hall effect devices. Advanced thermal management and a rugged aluminum housing enable stable performance to 3000 RPM with minimal backlash through high-resolution feedback and sinusoidal current command generation.
