MAC090A-0-ZD-4-C/110-A-1/WA604XX

The Bosch Rexroth Indramat MAC090A-0-ZD-4-C/110-A-1/WA604XX from the MAC AC Servo Motors series is a high-precision AC Servo Motor with a motor size 90 frame, delivering reliable performance in demanding automation tasks. This MAC Permanent Magnet Motor features a nominal speed of 2000 min-1 and a torque constant at 20 degrees C of 0.51 Nm/A, ensuring responsive torque generation under dynamic loads. With a compact length A design and a total mass of 12.5 kg, it balances robust power output with manageable inertia for rapid acceleration. The motor’s winding inductance is 1.9 mH, contributing to smooth current transitions and tight speed control.

Natural convection cooling maintains optimal operating temperatures across the rated thermal envelope, aided by a thermal time constant of 45 (30) minutes that indicates slow internal temperature rise under continuous load. The ZD winding construction supports stable magnetic flux and efficient heat dispersion during high-duty cycles. Rated to withstand a maximum peak of the pulse current of 53 A, the motor can handle brief overload conditions without derating. Furthermore, it is engineered to operate within a permissible ambient temperature range of 0 degrees C to 45 degrees C, allowing deployment in diverse factory and process environments without additional thermal management.

Integration is streamlined thanks to the power connector on Side A and the inclusion of a standard blocking brake for positive shaft holding in both powered and unpowered states. Feedback is provided via the built-in incremental encoder, which mounts in the motor’s standard position and ensures precise position and speed measurement. The combination of these features makes the MAC090A-0-ZD-4-C/110-A-1/WA604XX an ideal choice for machine tools, printing presses, packaging lines, robotic handling systems, and other applications requiring compact dimensions, high torque density, and reliable closed-loop control.
