MAC090B-0-ND-4-F/110-B-0/WI569LV

The MAC090B-0-ND-4-F/110-B-0/WI569LV from Bosch Rexroth Indramat represents a high-performance member of the MAC AC Servo Motors family, engineered for precision motion control in demanding industrial settings. This AC servo motor delivers a Continuous torque at standstill of 6.7 Nm, peaking at 10.5 Nm for dynamic load requirements. Rated for a Nominal motor speed of 3000 min-1, it accommodates both low- and high-speed applications. The design supports a Continuous current at standstill of 13.0 A, with a maximum pulse current surge of 98 A to handle rapid acceleration events. With a rotor optimized for inertia, the Rotor moment of inertia measures 36 x 10⁻⁴ kg·m², balancing torque buildup and dynamic response. At just Mass 18 kg, the compact form factor simplifies retrofits and new machine integrations.

Performance is driven by a finely tuned electromagnetic design featuring a Torque constant at 20 °C of 0.58 Nm/A and a winding assembly with Windings inductance of 3.9 mH. The winding copper resistance of Windings resistance at 20 °C 0.75 Ω ensures efficient heat distribution, while the Thermal time constant of 60 (45) min governs safe thermal run-up and cooldown cycles. The motor’s configuration includes an Incremental encoder with Standard Mounting for precision feedback, enabling closed-loop control systems to achieve repeatability within microradian resolution. Standard mechanical dimensions—Motor Size 90 and Motor Length B—facilitate direct replacement in established machine architectures. Natural heat dissipation through Cooling Type Natural Convection eliminates the need for auxiliary cooling circuits, reducing maintenance overhead.

Reliability is reinforced by a robust rotor and stator interface designed to withstand multi-axial shaft loads and maintain stable operation over millions of cycles. Although the unit is Not Equipped blocking brake, its friction-locked shaft end or optional keyway (DIN 6885 compliant) provides secure torque transmission and backlash-free coupling to gearboxes, pulleys, or direct-drive systems. The motor’s AC Servo Motor architecture integrates seamlessly with common drive controllers from Bosch Rexroth Indramat, offering auto-tuning, diagnostic monitoring, and protective interlocks. Ideal for robotics, packaging, and rotary indexing tables, the MAC090B-0-ND-4-F/110-B-0/WI569LV ensures high uptime and predictable performance in continuous-production or intermittent-duty applications.
