MAC093B-2-GS-3-C/110-A-1

The MAC093B-2-GS-3-C/110-A-1 is a high-performance AC servo motor designed by Bosch Rexroth Indramat for advanced automation tasks within the MAC AC Servo Motors series. This AC Servo Motor features a compact Motor Size of 93 and a Motor Length designation of B, providing an optimal balance between torque capacity and installation footprint. Its surface-cooled construction (Cooling Type: Surface Cooled) ensures efficient heat dissipation across continuous and peak load cycles. Equipped with a power connector on Side A, this motor supports robust slip-ringless operation and simplifies cable management in confined machine enclosures. The integrated encoder and blocking brake further enhance reliability and safety in dynamic motion control systems.

Built for demanding industrial environments, the MAC093B-2-GS-3-C/110-A-1 delivers up to Continuous current at standstill: 38 (53)^5) A and maintains a Continuous torque at standstill: 14.5 (20.0)^5) Nm without thermal overload. In pulse operation, it can handle a Maximum peak of pulse current: 192 A, enabling rapid acceleration and deceleration profiles. The motor achieves a Nominal motor speed: 4000 min^-1 in its constant torque range and maintains stable output down to low speeds thanks to its Torque constant at 20 °C: 0.388 Nm/A. Electrical characteristics include Windings inductance: 2 mH and Windings resistance at 20 °C: 0.136 ohm, which optimize responsiveness and minimize current ripple under high-bandwidth control. A Rotor moment of inertia: 29 x 10^-4 Kgm^2 ensures an excellent dynamic response for precision positioning tasks.

Operational reliability is reinforced by a Thermal time constant: 50 (45)^5) min, which provides strong overload tolerance during extended duty cycles and transient peak loads. The motor’s Mass: 16.5 kg contributes to robust mechanical stability, minimizing vibration and enhancing long-term service life. Lifetime-lubricated bearings and a standardized blocking brake eliminate the need for frequent maintenance and ensure immediate load holding when power is removed. Integrated hall effect sensors and tacho feedback deliver precise speed and position data to the drive controller, enabling closed-loop control with minimal latency. Surface cooling via the axial fan design maintains optimal winding temperatures, preventing thermal hotspots and extending insulation life.

Seamless integration with Rexroth drive electronics is facilitated through automatic electronic nameplate recognition and standardized communication protocols. The motor’s modular design supports straightforward mounting in gantry systems, robotic arms, packaging machines, and CNC equipment. With its combination of high continuous torque, rapid dynamic response, and robust protection features, the MAC093B-2-GS-3-C/110-A-1 is ideally suited for applications requiring precise motion control, such as semiconductor handling, medical device manufacturing, and high-speed assembly lines.
