Product Description:

The MAC090C-0-KD-4-C/110-B-1/DI524LX is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. As a motor for analog drives, it converts proportional current commands into controlled torque and speed, allowing closed-loop motion in packaging lines, transfer stations, and other industrial automation axes. The model pairs with Rexroth analog amplifiers to deliver precise rotary positioning and provides an integrated feedback path so the drive can monitor actual shaft movement in real time.

The motor uses a centering diameter of 110 mm, so it fits directly onto compatible gearboxes or machine frames without extra alignment bushings. The thermal load is handled by natural convection, so no external fan or liquid circuit is required when ambient airflow remains unobstructed. Under rated conditions, the rotor reaches 1500 min⁻¹, a speed that suits common 50 Hz and 60 Hz line-referenced processes when used with analog regulators. Power conductors are routed through a connector on side B, which simplifies cable management when the drive cabinet is located behind the axis. Electromagnetic characteristics follow the KD winding code, which matches the voltage constant and current limits expected by the associated drive electronics.

Dynamic accuracy is supported by a standard blocking brake, allowing the shaft to hold position when power is removed or during emergency stops. For velocity feedback, the built-in tacho generator produces 3 V/1000 min⁻¹, a value read directly by older analog amplifiers. Position loops benefit from the incremental encoder with shock-damped mounting, which reduces vibration transfer to the sensing elements. The encoder is part of a combined tacho feedback and incremental or absolute encoder arrangement, giving control systems digital position capture while retaining analog velocity feedback.
