Product Description:

The MAC112B-0-LD-4-C/130-A-2/WI524LV/S018 belongs to the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. It is a motor for analog drives that converts commanded current into precise torque and speed so machine axes can be positioned accurately under closed-loop control. Within an automation cell, the unit interfaces with legacy analog amplifiers, providing the rotary motion required for conveying, tooling, or coordinated gantry movement while its internal feedback devices relay real-time shaft data to the drive. This layout supports use in established machine platforms that still rely on analog motion hardware.

The motor’s centering flange is machined to 130 mm, allowing direct, accurate seating against standard IEC mounting faces. Cooling is handled by natural convection, meaning heat leaves the housing without the need for external blowers or liquid circuits. Under rated load, the rotor reaches a nominal speed of 2000 rpm, which supports common velocity setpoints and gearbox selection in packaging lines and pick-and-place systems. The integrated brake provides 60 Nm of static holding torque when power is removed. The LD winding sets the motor’s electrical characteristics, so compatible drives can supply the proper current without saturation.

A heavy-duty blocking brake resists repeated emergency stops and is suitable for vertical axes where load drift must be prevented. The three-phase power leads exit through a connector on side A, simplifying cable routing inside narrow machine frames. For position acquisition, the shaft is fitted with an incremental encoder that provides tachometer pulses and a coarse reference signal. These signals are complemented by a tacho generator that outputs 3 V/1000 rpm, helping analog velocity loops remain stable during low-speed creep or rapid accelerations.
