Product Description:

The MAC112C-0-HD-1-B/130-A-1/I1250/S05 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for analog drive systems, the unit converts electrical commands into controlled rotary motion for positioning axes, feeders, and transport stages in industrial automation. Its frame and electrical interface match legacy drive controllers used with this motor line. It is typically mounted to cast housings or linear slides where consistent torque and response are required. This layout supports repeatable motion during frequent start-stop cycles in older machine platforms that still rely on analog control architecture.

Mechanical holding is provided by a standard blocking brake that delivers 45 Nm of static torque, allowing vertical or load-holding axes to remain fixed when power is removed. The shaft seats against a 130 mm centering diameter so the motor can be aligned concentrically with gearboxes or machine plates. Heat generated during duty cycles is removed through natural convection, eliminating the need for forced air ducts or external coolant. Rotor position is returned to the drive through incremental encoder feedback, enabling velocity and phase control in the analog loop. For cabling, the power lead exits through a connector on side A, which keeps the terminals on the drive-facing side of a cabinet and simplifies routing. The electromagnetic layout follows winding code HD, which is used for high dynamic response at rated current.

Overall dimensions are set by the C length class and the frame size 112, combining a compact stator stack with enough thermal mass for continuous duty. The electromagnetic design reaches a nominal speed of 2000 rpm, allowing direct coupling to moderate-ratio gear stages without overspeeding. When operated with analog regulators, the built-in tacho generator returns 3 V/1000 rpm, giving the controller a proportional speed signal for closed-loop damping. This feedback arrangement supports stable speed regulation without requiring a separate external sensor.
