Product Description:

Bosch Rexroth Indramat's MAC112B-1-LD-4-C/180-A-2/AM164SG/S029 belongs to the MAC AC Servo Motors series. Supplied as a motor for analog drives, it converts controller current into rotary motion for positioning and velocity loops in automated machinery such as printing lines or transfer stations. The LD winding code, B length, and size 112 frame identify its electromagnetic package and overall footprint within the series, so the motor can be matched to different inertia and power requirements without changing the basic mounting interface.

Mechanically, the motor centers on a 180 mm pilot to align its housing with gearboxes or mounting flanges. A heavy-duty blocking brake delivers 60 Nm of static torque to hold vertical axes when power is removed. Heat generated in the stator is removed through axial surface cooling, assisted by an external blower rated at AC 230 V, which helps maintain thermal limits during continuous operation. Under rated conditions, the shaft reaches a nominal speed of 2000 rpm, giving the drive system a predictable velocity constant for synchronous control. Tacho, incremental, or absolute feedback devices can be mounted on the rear housing to provide real-time speed data, and the standard tacho quality supports general-purpose motion tasks.

Power is supplied through a connector on side A, keeping cable egress clear of coolant ducts and simplifying cable routing at the machine. Torque is transmitted through a DIN 6885 keyway, which helps prevent slip when the motor is coupled to pulleys or gears. Position feedback is upgraded to an absolute encoder, so each power-up reports a unique position reference without jogging. The tacho generator outputs 3 V/1000 rpm, which helps analog speed loops maintain stable feedback with low signal noise. The LD winding and the B-length stator support mid-range motion axes with a balanced response between current draw, dynamic behavior, and thermal rise.
