Product Description:

The MAC112C-0-HD-2-C/130-A is a synchronous AC servo motor produced by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. Designed as a motor for analog drives, it supplies regulated torque and speed to mechanical loads, allowing closed-loop automation equipment to execute precise positioning tasks, follow set velocity profiles, and maintain repeatability across multiple cycles in assembly stations or transfer systems. When energized at the rated drive voltage, the rotor reaches 2000 rpm, delivering the speed required for mid-range feed axes while still permitting direct gearbox coupling when higher torque multiplication is needed.

The mechanical interface uses a centering diameter of 130 mm, providing concentric alignment on mounting flanges so radial runout remains low and shaft coupling stress is minimized. Its housing coded as size 112 sets the stator outside diameter and matches bolt-circle dimensions that fit the standardized MAC mounting pattern. The length variant C extends the active iron stack, increasing continuous torque without changing footprint depth and letting machine builders raise power on the same bracket. Inside the stator, the winding set identified by code HD presents the impedance expected by analog drive amplifiers that regulate current with linear control loops.

Thermal management relies on natural convection, so the motor can be situated in cabinets or machine frames where airflow is limited but ambient temperature remains within typical industrial ranges. Velocity feedback is supplied by integrated tachometer feedback with standard quality for general-purpose motion loops. The tachogenerator outputs 3 V/1000 rpm, giving the drive a proportional signal that simplifies speed error computation without high-gain amplification. Power conductors exit through a connector on side A, enabling the cable bundle to follow the motor’s mounting face toward the drive cabinet and keeping the rear of the shaft clear for couplings or encoders demanded by the machine design.
