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

The MAC090B-0-JD-4-C/110-A-1/WA605XX servo motor from Bosch Rexroth Indramat is a high-performance unit in the MAC AC Servo Motors series, designed for precision motion control in demanding industrial environments. This MAC Permanent Magnet Motor features a compact Motor Size of 90 with a Motor Length of B, delivering robust performance in a space-efficient package. It incorporates surface cooling (radial surface cooling) for enhanced heat dissipation during continuous operation, complemented by Cooling Type: Natural Convection to maintain optimal thermal stability. The motor’s Insulation Classification: F ensures reliable winding integrity up to its maximum permitted winding temperature, while the Protection Category: IP65 rating provides full defense against dust ingress and water jets. A built-in 6.5 Nm holding brake secures the rotor when power is removed, making it ideal for applications that require immediate load retention.

Performance characteristics of the MAC090B series motor are defined by precise electrical and mechanical parameters. The Torque Constant of 0.41 Nm/A quantifies the torque output per unit of current, delivering responsive acceleration and deceleration. A Winding Resistance of 0.38 Ohm minimizes I²R losses for improved efficiency, while a Winding Inductance of 2.0 mH ensures controlled current dynamics and reduced sensitivity to supply fluctuations. The rotor’s Moment of Inertia: 36 x 10^-4 kgm^2 is calibrated for rapid speed changes without compromising stability. Short-term surge capacity is rated to a Maximum Peak of Pulse Current of 137 A, enabling high-torque bursts essential for dynamic positioning tasks. A Thermal Time Constant of 60 min reflects the motor’s ability to manage internal heat build-up, providing predictable thermal behavior under sustained load.

Engineered for reliable integration into automation systems, the MAC090B-0-JD-4-C/110-A-1/WA605XX balances rugged construction with precise control. Its IP65 protection rating and robust braking system make it suitable for packaging machinery, material handling, CNC equipment, and robotics where environmental exposure and load holding are critical. The use of Natural Convection and surface cooling simplifies installation by eliminating the need for external fans or water cooling loops. With standardized mounting dimensions and electrical interfaces, the motor can be paired seamlessly with Rexroth servo drives and controllers. Backed by a comprehensive one-year warranty, this servo motor delivers predictable performance, extended service life, and ease of maintenance in the most challenging industrial applications.
