MAC093C-1-FS-3-C/130-B-2

The MAC093C-1-FS-3-C/130-B-2 is a high-performance MAC AC Servo Motor engineered by Bosch Rexroth Indramat within the MAC AC Servo Motors series. This permanent magnet motor delivers a Rated speed of 3000 rpm and features a robust Motor Size of 93 with a compact Motor Length designation of C. Its Housing coat in Primal Black and Protection rating of IP65 ensure durability in harsh industrial environments. The motor’s weight of 23.1 kg, including the integrated holding brake, makes it suitable for medium-duty automation tasks with minimal spatial footprint. Equipped with a standard power connector on Side B, this unit also offers a C encoder, tachofeedback, and a second shaft end blocking brake for enhanced control.

Technically, the MAC093C-1-FS-3-C/130-B-2 excels in dynamic applications thanks to its low rotor moment of inertia of 45.6 x 10^-4 kgm2, optimizing acceleration and deceleration profiles. The winding characteristics include an inductance of 2.9 mH and a resistance of 0.175 Ω at 20 °C, enabling precise current control and minimal thermal losses. With an insulation capability defined by insulation class F, the motor withstands high operational temperatures while maintaining long-term stability. The integrated tacho generator provides a tacho voltage of 9 V and a voltage constant of 0.0286 Vs/rad, facilitating accurate speed feedback across its full speed range. A thermal time constant of 45 minutes affords reliable overload performance in intermittent duty cycles.

Operationally, this servo motor distinguishes itself with a holding brake rated as heavy duty, featuring a clamping delay of 30 ms and a release delay of 70 ms for immediate locking and release under emergency stop conditions. The brake’s additional moment of inertia of 3.6 x 10^-4 kgm2 integrates seamlessly with the motor’s rotor, ensuring stable position holding during power-off scenarios. Cooling is achieved via a Cooling Type of surface convection, maintaining optimal temperature without forced air systems. The motor’s permanent magnet excitation and electronic commutation deliver a high torque-to-inertia ratio, resulting in precise motion control and energy efficiency in repetitive positioning tasks.

Integration is streamlined through the standard power connector on Side B and compatibility with Bosch Rexroth Indramat drive controllers, supporting encoder type C and tachofeedback for closed-loop feedback control. A second shaft end blocking brake enhances safety by preventing unintended motion during maintenance or power loss. The MAC093C-1-FS-3-C/130-B-2 is ideal for machinery requiring compact footprint, reliable holding torque, and rapid response, including assembly robots, packaging equipment, and CNC automation systems.
