MAC112C-0-HD-4-C/130-A-0/S005

The Bosch Rexroth Indramat MAC112C-0-HD-4-C/130-A-0/S005 from the MAC AC Servo Motors series delivers exceptional dynamic performance with a continuous current at standstill of 41 A (67 A peak) and a continuous torque at standstill of 27.0 Nm (44.0 Nm peak). With a robust maximum peak of pulse current of 195 A and a nominal motor speed of 2000 min^-1, this MAC Permanent Magnet Motor combines high torque density and rapid response. The torque constant at 20 °C of 0.730 Nm/A ensures precise force generation, while the low windings resistance at 20 °C of 0.150 Ω and windings inductance of 2.5 mH optimize electrical efficiency. Encased in a frame weighing 48 kg and featuring a rotor moment of inertia of 170 x 10^-4 kg·m^2, the unit provides stable operation under rapid acceleration and deceleration.

Installation and integration are simplified by the Motor Size 112 and Motor Length C footprint, matching standard MAC series mounting dimensions. A thermal time constant of 100 min in natural convection cooling allows the motor to absorb intermittent peak loads without external cooling systems. The natural convection Cooling Type design eliminates moving parts, reducing maintenance and extending service intervals. The unit’s encoder interface supports a C encoder for incremental or absolute feedback, delivering high-resolution position data directly to the controller.

Routine commissioning checks should verify proper wiring and encoder signal integrity before running at the rated nominal speed of 2000 min^-1. Natural convection cooling and the built-in thermal protection threshold ensure safe operation up to the specified thermal limits. With its balanced mass and inertia characteristics, this servo motor provides consistent performance in precision automation applications, from indexing tables to conveyor systems.
