Product Description:

Bosch Rexroth Indramat produced the MAC112D-0-HD-3-C/130-A-2/S013 AC servo motor for the MAC AC Servo Motors series. The motor serves analog drive systems that require controlled torque, speed, and position loops. In industrial automation, it converts drive commands into mechanical rotation, enabling machine tools, printing lines, and material-handling axes to track analog setpoints accurately. A heavy-duty blocking brake secures the shaft when power is removed, preventing load drift on vertical axes or indexing stations. This braking arrangement is particularly useful when the connected mechanism must remain stationary without continuous motor torque.

The blocking brake delivers 60 Nm of holding torque, allowing gearboxes or lifting mechanisms to remain stationary during shutdown. Heat generated in the stator is dissipated through natural convection, eliminating the need for a cooling fan and reducing the motor’s maintenance requirements. The motor has a rated speed of 1500 rpm, which suits standard spindle, conveyor, and gearbox ratios. A flange pilot measuring 130 mm centers the housing accurately against the mounting face. Power is routed through a connector on side A, keeping the cable bundle near the driven equipment and supporting orderly routing within the machine. The electromagnetic core is housed in a 112 frame, providing a larger magnetic cross-section than smaller MAC motors and supporting greater continuous torque at comparable supply voltages.

Integrated tacho feedback supplies the drive electronics with real-time speed signals for closed-loop regulation. Its output of 3 V/1000 rpm matches the input range of compatible analog controllers and allows the drive to correct speed deviations as the load changes. The rotor stack uses the D length designation, adding iron depth to increase continuous torque without changing the flange profile. A second shaft end can accommodate an auxiliary encoder, a cooling fan, or a mechanical takeoff. This arrangement allows another device to share the motor axis without requiring a separate transmission path.
