Product Description:

The MAC112B-0-PD-3-C/130-A-0 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts command voltages from legacy controllers into controlled shaft motion for positioning or speed-regulated axes in industrial automation. This arrangement lets the connected drive amplifier regulate acceleration, running speed, and stopping behavior with repeatable response during continuous machine cycles. The unit is delivered without a blocking brake, making it suitable for installations where the drive or an external mechanism will hold the load when power is removed.

The motor uses a centering diameter of 130 mm, which aligns the housing precisely on a machine flange. Heat is removed through natural convection, so no fan or liquid circuit is required. Free airflow around the housing is therefore important when the motor is installed inside a machine enclosure or near other heat sources. The motor includes tacho feedback and a second shaft end, providing electrical speed information and a mechanical takeoff point for auxiliary devices. The rotor reaches a nominal speed of 1500 min⁻¹, which suits many common drive applications. Within that operating range, the built-in tacho generator produces 3 V per 1000 min⁻¹, allowing the analog drive to read velocity signals directly without added signal conditioning.

Electrical characteristics are tied to the PD winding set, so compatible drives see the expected phase resistance and inductance for stable current control. The stator uses size 112 in the MAC nomenclature, giving a standardized mounting footprint, while the active length corresponds to length code B, which balances torque output against motor mass. Power enters through a single connector on side A. This cable direction can help keep the power lead clear of adjacent machine hardware and simplify routing on right-hand layouts.
