Product Description:

The MAC112B-1-LD-4-C/180-A-1/AM164SG/S011 is a servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it supplies controlled mechanical power for positioning, speed, and torque regulation tasks in automated equipment. By converting drive current into precisely synchronized rotation, the unit supports closed-loop motion sequences in packaging lines, transfer stations, and machining centers where accurate axis control is required. This supports repeatable motion on automated axes that cycle frequently.

A standard blocking brake is integrated so loaded axes can be held when power is removed, and its holding capacity is 45 Nm. An axial surface cooling design with an external blower rated at AC 230 V moves air along the stator housing to maintain thermal stability during sustained duty cycles. Precise mechanical alignment is eased by a centering diameter of 180 mm, while shaft power is transferred through a DIN 6885 keyway that matches common hub components. The B length code joins the 112 frame size to fit medium-torque zones of the MAC family, and the LD winding pattern sets the resistance and inductance profile used by analog amplifiers.

During operation, the rotor reaches a nominal speed of 2000 min⁻¹, giving control loops enough range for rapid indexing without exceeding thermal limits. Position data are returned by an absolute encoder, and the feedback chain can be switched to incremental tacho signals when the control accepts a dual-channel configuration. The tacho output is proportional to speed at 3 V/1000 min⁻¹, and its quality grade is standard for general-purpose accuracy. Power conductors are routed through a connector on side A, so power and feedback connections remain on the same side of the motor housing.
