MAC090B-0-PD-4-C/110-A-1/WA605XX

The Bosch Rexroth Indramat MAC090B-0-PD-4-C/110-A-1/WA605XX from the MAC AC Servo Motors series is a high-performance MAC Permanent Magnet Motor designed for precision motion control in automated systems. It features a nominal motor speed of 2000 min^-1 and a continuous current at standstill rating of 11.9 A (17.4 A peak), ensuring reliable start-up torque for demanding applications. With a continuous torque at standstill of 7.2 Nm (10.5 Nm peak), this motor delivers smooth, controlled motion ideal for conveyor drives, robotic joints, and packaging machines.

Built on a robust Motor Size 90B frame, this servo motor employs natural convection cooling to maintain optimal operating temperatures without the risk of contamination associated with forced-air systems. The motor’s torque constant at 20 °C of 0.67 Nm/A and windings inductance of 5.1 mH ensure responsive torque control and minimal phase lag, while a windings resistance at 20 °C of 0.97 Ω provides predictable power consumption. A rotor moment of inertia of 36 x 10^-4 kg·m^2 delivers precise dynamic response, enabling fast acceleration and high positional accuracy. Integrated thermoswitches guard against thermal overload, extending motor lifespan in high-duty-cycle environments.

Designed for seamless integration, the MAC090B motor includes a standardized power connector on Side A and supports both incremental and absolute B encoder feedback systems, facilitating compatibility with a wide range of drives and controllers. The standard blocking brake utilizes 24 V DC actuation to cancel the permanent magnetic field, offering fail-safe holding torque and reduced maintenance compared to mechanical brakes. Weighing 18 kg with a thermal time constant of 60 min (45 min for peak) and a maximum pulse current of 86 A, this motor excels in continuous operation and intermittent duty. Its compact design, high efficiency, and robust construction make it ideal for industrial automation, enhancing machine uptime and precision in production processes.
