Product Description:
The MAC112D-0-FD-4-C 180-A-2 WI522LV/S019 is manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it supplies commanded torque and speed to linear stages and rotary actuators in automated production lines, packaging systems, and handling stations. Its mechanical build follows the 112 frame size with the D length code, giving it a consistent footprint for multi-axis layouts. It is suited to applications that need repeatable motion from a standalone motor paired with an external analog controller.
A heavy-duty blocking brake is integrated so that vertical or load-holding axes remain stationary during power loss. The brake’s holding capability is 60 Nm, which suits medium-inertia payloads used with this frame. Precise mounting is aided by a 180 mm centering diameter, which aligns the stator housing to machine platens without additional shims. Heat produced in normal duty cycles leaves the housing by natural convection, so no external blower is required. This cooling method also reduces the need for added hardware around the motor. Under rated excitation, the rotor reaches a nominal speed of 2000 rpm for analog drive amplifiers that regulate velocity with tacho feedback in mid-range motion profiles.
The electromagnetic circuit follows winding code FD, giving resistance and inductance values matched to legacy current-controlled amplifiers. Power conductors exit through a connector on side A, keeping cable routing on the same face as the feedback connection and reducing bend radius in tight enclosures. This cable orientation can also help when rear access around the motor is limited by machine framing. Speed feedback is provided by a tachogenerator that delivers 3 V/1000 rpm, which suits velocity loops that rely on proportional analog signals. For positional tasks, the motor carries an incremental encoder with standard mounting, enabling pulse counting up to the drive’s maximum frequency. The separate speed and position signals allow the motor to work with systems that use analog velocity control and incremental position monitoring.
