The Schneider Electric BCH2MR3523CA6C AC servo motor belongs to the BCH2 family and is designed for high‑power industrial automation applications when paired with a compatible Lexium 28 servo drive. At 3.5 kW output power, this servo motor delivers a balanced combination of torque, speed, and precision — making it ideal for medium‑to‑heavy machinery in manufacturing, processing, or production environments.
It features a substantial 180 mm flange and a 35 mm keyed shaft, ensuring secure mechanical coupling in demanding installations. With a maximum mechanical speed of 3000 rpm and nominal operating speed around 2000 rpm, BCH2MR3523CA6C accommodates both high-speed and heavy‑load requirements. Its nominal torque is 16.7 N·m, while peak (stall) torque reaches 50.3 N·m — enough for heavy load starts, acceleration, and dynamic operation.
The integrated 20‑bit single‑turn absolute encoder provides accurate position feedback for precise motion control, without needing external sensors. The motor’s design includes oil‑seal and keyed shaft configuration and supports straight electrical connection via a MIL connector, facilitating straightforward installation.
Given its robust design, power, and feedback capabilities, this servo motor is well suited for CNC machines, heavy material handling conveyors, industrial presses, packaging machinery, printing or assembly lines, and other automation systems demanding reliable torque, precision, and durability under load.
