Product Description:

The MAC112D-0-ED-4-B/130-A-0/WI524/S05 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is specified as a motor for analog drives, supplying torque and speed control to legacy CNC axes and general-purpose industrial positioning systems. By integrating tachometer and encoder feedback in one housing, the unit streamlines closed-loop regulation tasks commonly handled by analog amplifier racks. This arrangement lets the connected drive monitor motor behavior continuously and correct deviations during acceleration, deceleration, and steady-state motion.

The motor size of 112 sets the external frame envelope used for mechanical interchangeability with other MAC units. A centering diameter of 130 mm provides the pilot surface that aligns the flange to gearboxes or machine plates. Length code D denotes a longer magnetic stack, which supports higher continuous torque without changing the mounting pattern. Its nominal speed of 3000 rpm gives the drive a predictable operating ceiling during normal axis control. Cooling is handled by natural convection, so housing fins dissipate losses without forced airflow. Winding code ED marks the electrical design used with analog amplifiers, helping the motor match the expected current and voltage behavior of compatible controllers.

For velocity feedback, the built-in tachogenerator delivers 3 V/1000 rpm, supplying a linear analog signal to legacy drive cards. Power conductors exit through a connector on side A, which fixes cable orientation and can simplify routing where cabinet space is limited. Position information is supplied by an incremental encoder mounted in the standard housing interface, and the wiring harness can support optional absolute modules when required. Because the motor has no blocking brake, vertical axes must rely on external holding hardware or drive-generated torque when power is removed. The combination of speed feedback and position feedback allows one motor housing to support stable regulation in applications that still use analog control architecture.
