Product Description:
The MAC112C-0-ED-2-C/130-B-1/ is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drive systems, the unit converts drive current into regulated mechanical motion for industrial automation axes that need repeatable velocity and position control. An integrated blocking brake holds the shaft when power is removed, and tachometer feedback supplies real-time speed data to the drive for closed-loop regulation. This layout suits installed systems that rely on classic servo amplifiers rather than fully digital motor feedback. It is suited to machine axes that need steady speed control and repeatable stopping behavior during routine cycling.
At a nominal speed of 3000 rpm, the motor supports continuous operation in conveyor, tooling, and packaging lines that use this rated speed. The frame follows size code 112 and stack length code C, which set the housing proportions and active motor length for this model. Thermal energy leaves the stator by natural convection, so mounting should leave clear space for airflow around the ribs. The passive cooling method avoids auxiliary fan hardware on the motor housing. Power conductors enter through a connector on side B, which can simplify cable routing when the shaft faces the machine load. Motor speed is reported by an internal tachogenerator, enabling the analog controller to compare commanded and actual values with minimal delay.
The mechanical interface uses a centering pilot of 130 mm, which aligns the flange accurately against gearboxes or adapter plates and helps reduce radial runout. When the brake engages, it provides a holding torque of 45 Nm, helping prevent load back-drive on vertical or indexing stations. The winding code ED indicates the electrical characteristics used by legacy MAC drives. Tachometer output equals 3 V/1000 rpm, giving the controller a proportional voltage signal that scales linearly with motor speed. This signal format can be used directly by compatible analog servo controllers.
