MAC090B-0-JD-4-C/110-A-2/WA604XX/S013

The MAC090B-0-JD-4-C/110-A-2/WA604XX/S013 from Bosch Rexroth Indramat is a high-performance member of the MAC AC Servo Motors series, designed for demanding industrial motion control applications. This AC Servo Motor features a Motor Size of 90 and a compact Motor Length of B, combining power density with a small footprint. With a nominal motor speed of 3000 min-1 and a continuous torque at standstill rating of 6.7 (10.5) Nm, it delivers reliable torque for precision positioning tasks. The motor’s integrated power connector on Side A and modular feedback options streamline installation and setup across a variety of control platforms. Its robust design accommodates a wide range of operating conditions while maintaining consistent performance.

Technical capabilities are at the core of this servo motor’s appeal. It requires a continuous current at standstill of 18.2 (28.5) Amperes to produce rated torque, and can withstand a maximum peak of pulse current of 137 A during high-demand cycles. The rotor’s rotor moment of inertia of 36 x 10-4 kgm2 supports rapid acceleration and deceleration sequences. Precision is enhanced by a torque constant at 20 °C of 0.41 Nm/A, while electrical responsiveness is defined by a windings resistance at 20 °C of 0.38 Ohm and windings inductance of 2.0 mH. With a thermal time constant of 60 (45) minutes, the motor can sustain intermittent peak loads without thermal degradation.

Operational features deliver both reliability and efficiency in continuous use. The motor’s Cooling Type of natural convection ensures stable thermal management without external fans, contributing to a lightweight design at a mass of approx. 3.2 kg (radial cooling). The natural-convection cooling strategy couples with the thermal time constant to maintain optimal winding temperatures under variable load profiles. High peak current capability supports dynamic motion profiles, while the durable construction minimizes maintenance requirements in harsh environments. Seamless integration with tachogenerator and encoder options further enhances closed-loop control accuracy and system responsiveness.

Integration and application flexibility make this motor suitable for a wide spectrum of automation tasks. Its standardized form factor and power connector arrangement simplify replacement and retrofitting in machine tools, packaging lines, and conveyor systems. Engineers can leverage the consistent nominal motor speed and broad torque range to optimize performance in multi-axis setups and robotics. Compatibility with Bosch Rexroth Indramat drive controllers and feedback modules ensures precise synchronization and scalable motion solutions across diverse industrial installations.
