MAC090B-0-JD-1-B/110-A-1/-I00625/S021

The MAC090B-0-JD-1-B/110-A-1/-I00625/S021 from Bosch Rexroth Indramat in the MAC AC Servo Motors series is a high-performance AC Servo Motor MAC that delivers precision motion control in a compact 90-B frame. It features a Motor Size 90 with a Motor Length B housing and employs Cooling Type Natural Convection to eliminate the need for auxiliary fans. Rated for a Continuous current at standstill 18.2 A and delivering a Continuous torque at standstill 6.7 Nm, it maintains steady output under load. The integrated brake provides a Holding torque of brake 6.5 Nm for secure locking in position.

Built for dynamic applications, this motor tolerates a Maximum peak of pulse current 137 A and spins at a Nominal motor speed 3000 min^-1 for rapid acceleration. Its Torque constant at 20 °C 0.41 Nm/A ensures accurate torque-to-current conversion, while Windings inductance 2 mH and Windings resistance at 20 °C 0.38 ohms contribute to predictable electrical dynamics. With a Thermal time constant 60 min the design dissipates heat efficiently, and built-in thermal switches within the stator housing protect against overheating. A standard mounting encoder and blocking brake enable closed-loop feedback and reliable holding performance.

Engineered for low inertia and linear torque-speed characteristics, the MAC090B excels in precision indexing, positioning, and speed regulation without brushes or slip rings. Its IP65-rated enclosure and noiseless operation lower maintenance demands and extend service intervals. The result is a robust servo solution that integrates seamlessly into automation systems requiring compact size, stable torque output, and long-term reliability.
