MAC090A-0-RD-3-C/110-B-0/S001

The Bosch Rexroth Indramat MAC090A-0-RD-3-C/110-B-0/S001 is part of the renowned MAC AC Servo Motors series, designed to deliver precision control and robust performance in demanding automation environments. With a compact Motor Size of 90 and a lightweight construction weighing just 12.5 kg, this servo motor achieves a nominal speed of 3000 min-1 while maintaining high dynamic responsiveness. The motor’s permanent excited magnetic design integrates seamlessly with a Power connection on Side B, facilitating straightforward installation and wiring. Engineered for versatile mounting, the unit features a B05 flange interface with through holes, enabling flexible orientation and secure attachment in various machine architectures. Its natural cooling method, specified as Cooling Type Natural Convection, ensures efficient heat dissipation without the need for additional cooling devices.

Performance characteristics of the MAC090A model emphasize rapid response and sustained torque delivery. The rotor’s Rotor moment of inertia of 20 x 10-4 kg·m2 and a Torque constant at 20 °C of 0.900 Nm/A produce a standstill continuous torque of 3.5 Nm, while supporting peak current surges up to Maximum Peak Pulse Current of 76 A for transient loads. Electrical parameters such as Windings resistance at 20 °C of 0.24 Ohm help optimize current flow and minimize thermal buildup, complemented by a Thermal Time Constant of 45 minutes for predictable thermal behavior under cycling loads. Although the unit does not include a Blocking brake No, its built-in tachofeedback system provides accurate speed and position monitoring for closed-loop control. The robust winding and insulation materials sustain rigorous duty cycles, and the flange with through holes simplifies mechanical integration in high-speed transfer lines and robotic assemblies.

Reliability is further enhanced by integrated thermal switches that prevent overheating by interrupting current when internal temperatures exceed safe limits. The MAC090A motor supports operation in ambient temperatures from Permissible Ambient Temperature 0°C to +45°C and can be transported in conditions down to –20°C or up to +80°C, ensuring durability throughout the supply chain. Its IP65 protection rating offers complete sealing against dust and low-pressure water jets, making it suitable for wash-down or dusty environments. The floating bearing design on side A absorbs radial loads while side B manages axial forces, guaranteeing extended bearing life and minimal maintenance. Ideal for robotics, handling equipment, transfer facilities, and other precision automation applications, this servo motor combines rugged construction with high-precision control for seamless integration into complex industrial systems.
