Product Description:

The MAC112B-0-LD-4-C/130-B-1/AM164SG/S005 belongs to the MAC AC Servo Motors series engineered by Bosch Rexroth Indramat. It is a motor for analog drives that provides closed-loop speed and position control for machining centers, printing lines, and other automated axes. The model integrates a standard blocking brake so driven loads can be held when power is removed. It also supports tachometer or encoder feedback so external controllers can monitor motion and correct deviations during operation. This makes it suitable for axes that must start, stop, and hold position with repeatable response during normal production cycles.

This motor reaches a nominal speed of 2000 rpm, a value matched to drive stages that regulate spindle or feed rates precisely. The integrated brake supplies 45 Nm of holding torque, which helps keep vertical or high-inertia loads stationary when the axis is stopped. A centering diameter of 130 mm aligns the housing in a pilot recess, and the shaft uses a DIN 6885 keyway so couplings can transmit torque without slip. Heat from the windings is removed by natural convection, eliminating the need for external blowers. Because cooling does not depend on forced airflow, the motor can be installed without adding separate fan hardware around the housing. Frame size 112 with B-length construction gives the motor a moderate installation envelope while still supporting continuous industrial duty.

The power connector is oriented toward side B, which can simplify cable routing when adjacent machine parts limit access around the drive end. Position feedback is supplied by an integrated absolute encoder, giving the control system rotor angle information immediately after power-up. The tacho produces 3 V/1000 rpm, a signal level commonly used by analog velocity loops for stable speed regulation. That combination allows the drive to use the analog speed signal while retaining an absolute position reference for controlled restarts. The LD winding code identifies the electrical winding arrangement used for this motor and supports proper matching with compatible drive amplifiers.
