Aerotech 1050DC-MSO1 E500 Permanent Magnet Servo Motor

Aerotech 1050DC-MSO1 E500 Permanent Magnet Servo Motor is a 1,050-series permanent-magnet servo motor from Aerotech's DC servo family, designed for compact, high-precision single-axis motion. It features a 0.25 in shaft diameter and MSO1 mounting footprint for straightforward integration into tight assemblies. The E500 encoder option provides 500 lines per revolution, enabling fine position and velocity feedback for accurate servo control. In continuous-torque terms, the 1050-size unit delivers about 50 oz-in (approximately 0.35–0.4 N·m), with a peak torque around 186 oz-in (roughly 1.3 N·m), supporting brisk acceleration within its torque band. The motor achieves a nominal speed near 4,200 rpm, and is powered from a 40 V DC bus with a 5 A fuse, reflecting its compact, electronics-friendly drive requirements. Weight is about 3.8 lb (1.7 kg) and rotor inertia is about 8×10^-3 oz-in·s^2 (57×10^-6 kg·m^2), indicating responsive dynamic performance. With an approximate motor output of 115 W, the 1050DC-MSO1 is a compact, high-performance option in Aerotech’s 1000 Series for precision motion control in single-axis systems where a reliable, encoder-rich motor is needed.
