Product Description:

The MAC112D-0-ED-4-C/180-A-1/WI522LV/S032 is an AC servo motor built by Bosch Rexroth Indramat as a member of the MAC AC Servo Motors series. Intended for integration with analog drive controllers, the unit converts drive current into controlled rotary motion for positioning or velocity loops on automated machine axes. Within industrial automation, it delivers the closed-loop performance needed for packaging machinery, handling robots, and material processing stations where tight speed regulation and repeatable accuracy are required. It is also suited for machine axes that need steady low-speed control and responsive acceleration across a broad operating range.

The housing centers on a 180 mm pilot diameter that aligns the flange to gearboxes or mounting plates, reducing radial offset during installation. A blocking brake rated at 45 Nm holds the shaft when power is removed, helping prevent drift on vertical or inertially loaded axes. Heat is removed through natural convection, so no external blower or liquid circuit is required. This cooling method keeps the motor enclosure simple and avoids auxiliary fan hardware. Under rated excitation, the rotor reaches 3000 rpm, which suits transmission ratios common in medium-inertia systems. Power conductors terminate at a connector on side A, which can simplify cable routing when multiple motors share the same panel orientation.

Tachometric feedback generates 3 V/1000 rpm, so the drive can derive real-time speed error without an additional sensor channel, and the standard tacho quality is suitable for most contouring or feed applications. Position feedback is provided by an incremental encoder that mounts in the prescribed mechanical interface for this model. The ED winding code indicates the electrical values used when tuning current loops, while motor length D indicates the active iron stack used for continuous torque. The encoder and tacho signals give the connected drive separate channels for position monitoring and speed response.
