Product Description:

The MAC112B-0-LD-4-C/130-A-2/W1524LV/S018 is an AC servo motor produced by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. Built for analog drives, it works with classic velocity and current loop controllers to deliver closed-loop rotary motion in automated production equipment. Its mechanical shaft couples directly to gearboxes, pulleys, or similar driven elements, allowing commanded motion to be transferred to packaging, printing, and material-handling axes. Because the motor is intended for analog control architectures, the external amplifier can use returned speed information to correct for load changes and keep motion smooth during repeated cycles.

At standstill, the brake can resist 60 Nm of shaft torque, which helps hold vertical or indexing axes when drive power is removed. A centering pilot of 130 mm aligns the frame with precision mounting flanges and helps reduce runout during operation. The stator winding code LD is paired with motor magnetics that support a nominal speed of 2000 rpm. Heat is removed through natural convection, so no external blower is required when the installation provides adequate airflow. This cooling approach keeps the housing simple and avoids the added wiring associated with fan-assisted designs. The motor has length code B and includes a standard-grade tacho for speed feedback in analog velocity loops.

The installed heavy-duty blocking brake releases only when energized, which supports load retention when the axis is stopped. Electrical power is connected through a connector on side A, which helps simplify cable routing along the machine frame. Frame designation 112 identifies the stator diameter and bolt circle used for this motor size. The tacho generator outputs 3 V/1000 rpm, and the feedback electronics can be configured for incremental or absolute tacho feedback to suit different controller types. This signal gives the drive a direct speed reference for low-speed regulation and stable operation.
