Product Description:

The MAC112C-0-HD-4-C/180-A-2/WI520LV/S029 is manufactured by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. It is a motor for analog drives that delivers controlled torque and speed to automated axes, allowing machining centers, gantry stages, and material-handling equipment to follow commanded motion profiles with repeatable accuracy. A permanently excited rotor, integrated tacho feedback, and encoder mounting allow the drive controller to regulate position and speed in a closed loop. This arrangement helps the motor respond to load changes while maintaining steady motion on positioning and speed-regulated axes. It is suited to equipment that relies on predictable acceleration and repeatable stopping behavior.

This model includes a heavy-duty blocking brake that can hold the shaft with 60 Nm of static torque during power-off states. A centering pilot of 180 mm aligns the housing on the machine interface and helps keep radial runout low during installation. Heat produced in the windings is removed by natural convection, so no external blower or liquid circuit is required. Power conductors enter through a connector on side A, which can simplify cable routing where enclosure space is limited. Under rated excitation, the rotor reaches 2000 rpm, allowing direct coupling to gear stages or belt transmissions that require medium-speed operation without overspeeding the bearings.

Shaft torque is transmitted through a DIN 6885 keyway, giving positive engagement with couplings or pulleys. For velocity feedback, the internal tacho generates 3 V/1000 rpm, and position data comes from an integrated incremental encoder fitted with standard mounting hardware. The feedback signals allow the controller to track shaft movement continuously during operation. Winding code HD identifies the motor's electromagnetic layout, including resistance, inductance, and current constants used by the matching analog drive. These features support stable holding, smooth low-speed rotation, and consistent dynamic response during indexing, contouring, and other repeatable motion tasks.
