Product Description:

The Bosch Rexroth Indramat MAC093B-0-GS-4-C/110-A-3/W1520LV/S005 is an AC servo motor in the MAC AC Servo Motors series. Designed for integration with analog velocity or position controllers, the unit converts drive commands into precise rotary motion for automated machines and transfer lines. It belongs to the 093 frame size, which balances torque density with a compact housing and makes the motor suitable for axes that require high dynamic response in limited installation space.

The mechanical reference surface features a centering pilot of 110 mm, giving the flange repeatable concentricity during installation. An integrated brake delivers up to 22 Nm, so vertical or intermittent-load shafts remain fixed when the drive is disabled. Under rated excitation, the rotor can sustain 4000 rpm, and waste heat is removed through natural convection, which permits mounting in sealed enclosures without forced airflow. The tachogenerator produces 1.5 V/1000 rpm; this signal, together with the encoder channel, feeds directly into analog servo amplifiers. All power conductors terminate on a connector positioned on side A of the stator, simplifying cable routing parallel to adjacent axes.

The shaft transmits torque through a DIN 6885 keyway, allowing direct coupling to pulleys or gears without additional machining. Behind the flange, the motor length corresponds to code B, providing a mid-range stack height that limits inertia yet leaves space for the internal windings identified by code GS. Holding force is supplied by an extra heavy-duty blocking brake, a design that complements the 22 Nm rating by using enlarged friction surfaces and supporting long service life during frequent stops. Standard tacho quality completes the feedback scheme and keeps the voltage slope linear across the speed band.
