MAC090C-0-KD-4-C/110-B-1/AM164SG

The MAC090C-0-KD-4-C/110-B-1/AM164SG is a robust AC servo motor from Bosch Rexroth Indramat’s MAC AC Servo Motors lineup, engineered for precision automation applications. Featuring a nominal speed of 2000 rpm and a continuous torque of 10.4 Nm, this motor delivers consistent performance for dynamic industrial tasks. It employs a natural convection cooling system complemented by a thermal time constant of 60 mins to maintain optimal operating temperatures. The unit integrates both tacho feedback and a mounted incremental encoder for accurate position and velocity monitoring, and includes an electrically-released 6.5 Nm holding brake for secure stoppage under load. Built on a Motor Size 90 frame with a Motor Length C and a centering diameter of 110 mm, it balances power density and compact form factor.

Technical capabilities of the MAC090C-0-KD-4-C/110-B-1/AM164SG are underscored by its continuous current rating of 17 A at standstill, enabling steady torque delivery without thermal overload. The motor meets Protection Category IP65 standards, safeguarding internal components against dust and water ingress. Its insulation category F rating supports operation up to elevated winding temperatures, while the operating temperature range of 0 to +45 degree Celsius ensures reliable performance across common factory environments. As part of the AC Servo Motor MAC family, it leverages Rexroth’s proven design for low vibration and high dynamic response. The combination of natural convection cooling and a robust frame enhances its suitability for sustained cycles in high-duty applications.

Operational features of the motor include a quick-response holding brake with a 6.5 Nm braking torque to secure loads immediately upon power loss or command. The integrated incremental encoder and tacho generator provide redundant feedback channels, improving failsafe monitoring and closed-loop control stability. With a compact centering diameter of 110 mm and both B05 and B14 flange compatibility, installation flexibility is maximized in varied machine designs. The side-B power connector, paired with standard INK 250 or INK 650 cables (1.5 mm² cross-section), simplifies field wiring and maintenance. The motor’s overall weight of 23 kg and balanced inertia characteristics support nimble acceleration profiles without compromising structural integrity.

Designed for seamless integration, this servo motor interfaces directly with Rexroth Indramat servo drive modules via U1, V1, W1 terminals, enabling plug-and-play commissioning. Its compact form factor and flange options make it ideal for robotics, packaging machinery, CNC tooling, and other precision automation systems. The IP65 rating and F-class insulation extend system uptime in harsh environments, while the standardized motor dimensions facilitate modular machine architectures. With consistent torque delivery, precise feedback mechanisms, and robust thermal management, the MAC090C-0-KD-4-C/110-B-1/AM164SG is a versatile solution for demanding industrial applications.
