MAC025B-0-ZS-4-E/040-A-0/WI652LV/S001

The Bosch Rexroth Indramat MAC025B-0-ZS-4-E/040-A-0/WI652LV/S001 AC servo motor from the MAC AC Servo Motors series delivers a robust solution for industrial automation, combining reliable performance with compact design. This 12.5 kg motor provides a continuous standstill torque of 3.7 Nm, ensuring precise holding capability under static loads. With a nominal speed of 10000 min⁻¹, it achieves rapid dynamic response for high-speed motion applications. Encased to IP65 protection category, the motor resists dust and water ingress, making it suitable for demanding factory environments where contamination is a concern. An integrated incremental encoder with standard mounting offers accurate position feedback for closed-loop control systems.

Detailed technical characteristics underpin the MAC025B design. It operates with a continuous current rating of 2.38 A and exhibits a torque constant of 0.22 Nm/A, providing predictable torque output under varying electrical input. The rotor moment of inertia is 0.32 x 10⁻⁴ kgm², which contributes to low overshoot and rapid acceleration. Thermal management relies on natural convection cooling and a thermal time constant of 45 minutes, ensuring stable temperature rise during extended operation. Insulation classification of Class F guarantees reliable performance under elevated thermal stress, while the absence of blocking brakes simplifies maintenance and reduces weight.

Operational features emphasize reliability and precision. The motor's tacho constant of 0.75 V/1000 min⁻¹ supplies proportional voltage feedback for speed monitoring and control. A broad operating temperature range from -20 to +80 °C enables use in both cold-storage and hot-process applications without additional heating or cooling provisions. The natural convection cooling method eliminates the need for auxiliary fans, reducing noise and minimizing particulate cleanup. At a mass of 12.5 kg, the motor balances inertia and rigidity, supporting stable operation even in high-acceleration cycles.

System integration is facilitated by standard encoder mounting and compatibility with common servo drives in industrial environments. The motor’s IP65 rating and robust construction make it ideal for packaging machinery, CNC equipment, and robotic axis modules. Its precise feedback and predictable torque behavior support advanced motion profiles in assembly lines, pick-and-place systems, and material handling platforms. The compact footprint of the MAC025B series accelerates machine design, enabling higher throughput in automation installations where space and reliability are critical.
