Product Description:

The MAC112C-0-HD-2-C/130-A-0 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. As a motor for analog drives, it converts command voltages into controlled torque and speed for axis positioning, winding, and feed operations on production lines. By combining a permanent-magnet rotor with integrated tacho feedback, the unit delivers closed-loop performance without separate sensors. This arrangement supports stable response in machines that use analog amplifiers for continuous speed and position control.

A centering diameter of 130 mm allows the housing to seat accurately against machine mounting faces and helps maintain shaft concentricity. Heat is removed through natural convection, so no external blower or liquid circuit is required. The armature uses winding code HD, which is intended for the high-torque operating characteristics of this motor version. Under rated excitation, the shaft reaches 2000 rpm, giving the drive a balanced operating speed for analog control loops. The integrated tachogenerator produces 3 V/1000 rpm, supplying a proportional velocity signal that supports stable closed-loop regulation during changing load conditions.

The motor uses length code C and frame size 112, matching common MAC mounting patterns for this platform. Power conductors connect through a connector on side A, which keeps cable routing consistent with machine layouts that bring motor leads in from that direction. Velocity information comes directly from the built-in tacho feedback and is intended for general-purpose motion control. The motor is supplied without a blocking brake, so holding torque during power-off must be provided by the mechanical load arrangement or by an external holding device. This is important in applications where the axis must remain fixed after drive power is removed.
