MAC AC Servo Motors
The Bosch Rexroth Indramat MAC090B-0-JD-4-C/110-A-1/WA604XX from the MAC AC Servo Motors series is a high-performance permanent magnet motor manufactured by Bosch Rexroth Indramat. It features a winding resistance (RA) of 0.75 Ohm and a winding inductance (LA) of 3.9 mH at 20 °C, ensuring rapid current changes with minimal energy loss. The torque constant (km) of 0.580 Nm/A at 20 °C provides precise torque control, delivering consistent performance across a range of speeds. A dedicated power connector on Side A, integrated B encoder, and standard blocking brake facilitate straightforward integration and safe operation.
This servo motor supports a continuous current at standstill (IdN) of 13.0 A under natural convection, boosting to 20.0 A with optional surface cooling for extended duty cycles. It provides a continuous torque at standstill (MdN) of 6.7 Nm, ideal for holding and low-speed positioning tasks. For dynamic applications, the maximum peak of pulse current (Ipeak) is 98 A, enabling short bursts of high acceleration. The motor sustains a nominal speed (n) of 3000 min^-1 while managing thermal loads with a thermal time constant (Tth) of 60 min.
Designed for fast-response motion control, the motor’s rotor moment of inertia (JM) of 36 x 10^-4 kgm^2 balances inertia and agility, optimizing acceleration and deceleration profiles. Certified for long-term reliability, the MAC090B-0-JD-4-C/110-A-1/WA604XX excels in applications requiring precise positioning, repeatable torque, and robust braking. Its consistent mechanical footprint and standardized electrical interfaces make it a versatile choice for OEMs in packaging, robotics, and CNC machinery.
