MAC112C-0-ED-2-C/180-B-1/S012

The MAC112C-0-ED-2-C/180-B-1/S012 servo motor from Bosch Rexroth Indramat is a high-performance member of the MAC AC Servo Motors family, engineered for precision motion control in automated systems. This unit features a robust Motor Size 112 and a compact Motor Length C profile, optimized for both B05 and B14 mounting configurations. With a mass of 48 kg, it delivers a compelling power-to-weight ratio suitable for demanding industrial environments. Rated for a nominal motor speed of 3000 min⁻¹, the motor ensures consistent rotational performance across its operational range. The integrated design includes a natural convection cooling type that eliminates the need for auxiliary fans, simplifying installation and reducing maintenance requirements.

Performance is driven by a suite of finely tuned electrical and mechanical parameters. The motor provides a continuous current at standstill of 57 A (surge capacity up to 104 A) and generates a continuous torque at standstill of 24.0 Nm (with peak capability up to 44.0 Nm), supporting rapid acceleration and heavy load starts. Its maximum peak of pulse current of 312 A enables swift torque delivery during dynamic cycles. At 20 °C, the torque constant of 0.470 Nm/A ensures precise current-to-torque conversion, while the windings inductance of 1.0 mH and windings resistance of 0.060 Ω deliver fast electrical response and minimal losses. The rotor moment of inertia of 170 × 10⁻⁴ kg·m² combined with a thermal time constant of 100 min (75 min in continuous surge mode) guarantees stable thermal performance under prolonged duty. Collectively, these characteristics achieve exceptional control accuracy and energy efficiency, making the motor ideal for high-dynamic applications.

Reliability and integration were key considerations in the design of this servo motor. A standard blocking brake rated at 45 Nm provides secure holding torque in static positions, enhancing safety during power-off conditions. The C encoder interface allows for direct feedback integration with advanced motion controllers, delivering high-resolution position information. The power connector located on the B-side simplifies wiring and reduces installation time. Its compatibility with both B05 and B14 flange designs ensures seamless retrofitting into existing drive systems. Suitable for robotics, packaging machinery, CNC equipment, and other automated processes, the MAC112C model excels in applications requiring robust operation, precise positioning, and long service life.
