Product Description:

The MAC112B-0-LD-3-C/130-A-1 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is supplied as a motor for analog drives and is used to provide closed-loop axis motion in industrial automation equipment such as packaging stations and material-handling modules. An integral blocking brake holds the load when power is removed, which helps the axis remain in position during stops or power loss. A tacho mounted on the second shaft end supplies velocity feedback to legacy drive electronics, allowing the controller to monitor motor speed during normal operation.

The motor’s blocking brake delivers 45 Nm of static holding torque, allowing vertical or overhung loads to remain fixed during shutdown. A frame centering diameter of 130 mm matches the motor to standard flange adapters so alignment errors are minimized during installation. With a nominal speed rating of 2000 rpm, the rotor can follow typical analog command voltages without exceeding normal operating speed. The frame size code 112 indicates the motor’s mechanical platform, and winding code LD identifies the electrical winding used with compatible drive amplifiers. These ratings help determine how the motor fits the axis layout and how the connected drive regulates current and speed.

Cooling is provided by natural convection, so no external blower is required for continuous operation. The tachogenerator outputs 3 V/1000 rpm, giving the drive a proportional speed signal for responsive velocity control. Power conductors are routed through a connector on side A, which can simplify cable routing when the motor is installed with the service end toward the machine wall. The mechanical length code B indicates a shorter housing than longer stack versions in the same frame family. The second shaft end used for tachofeedback also allows the feedback device to remain separate from the primary driven connection.
