MAC093C-1-FS-3-C/110-B-0

The MAC093C-1-FS-3-C/110-B-0 from Bosch Rexroth Indramat belongs to the distinguished MAC AC Servo Motors series, engineered for precision motion control in industrial automation. This MAC Permanent Magnet Motor variant features a nominal rated speed of 3000 rpm and delivers a continuous torque at standstill of 28 Nm driven by a continuous current of 50 A. With a total weight of 22 kg (without holding brake and encoder), the compact design incorporates a surface-cooled axial blower cooled housing rated at 230 V AC power supply. The motor’s centering diameter of 110 mm accommodates both B05 and B14 flange types, ensuring mechanical compatibility across diverse installations. Electrical power input is located on Side B, while the absence of a blocking brake simplifies mounting and maintenance procedures.

Performance is further enhanced by the standard tacho feedback system generating a 9 V tacho voltage, supplemented by a second shaft end for auxiliary attachments. The motor’s dynamic response is governed by a thermal time constant of 45 mins and class F insulation capable of withstanding up to 311°F continuous operation. Winding characteristics, including a resistance of 0.175 ohm and an inductance of 2.9 mH, enable stable current flow and minimized electrical losses. Peak acceleration currents reach up to 173 A pulse current, supporting rapid torque delivery for transient loads. Voltage requirements vary with speed: 3 V per 1000 rpm above the rated speed and 1.5 V per 1000 rpm below, optimizing efficiency across the operational spectrum.

Reliability is assured by an IP65 protection rating under IEC 60529, safeguarding the motor from dust ingress and water jets. The robust housing coat in RAL-9005 finish resists corrosion in harsh environments, while the MAC093C-1-FS-3-C/110-B-0’s compatibility with standard C‐type encoders ensures seamless integration into existing control architectures. With no holding brake fitted, this model streamlines applications requiring direct-drive coupling and low inertia. Its balance of torque density, thermal stability, and enclosure resilience makes it ideal for CNC machinery, robotics, packaging lines, and other high-precision motion systems where consistent performance and straightforward installation are paramount.
