Product Description:

The MAC093C-0-FS-4-C/110-A-3/WI520LV is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. This model has motor size 093 and length class C, which gives it a consistent mechanical envelope for retrofit work on analog velocity loops. Classified as a motor for analog drives, it converts electrical input into controlled rotary motion for machine axes that use ±10 V command structures and tachometer feedback to close the speed loop. Its layout suits motion tasks that require steady speed regulation and repeatable axis response in established automation platforms.

An extra heavy-duty blocking brake is integrated to hold loads during power-off conditions, and it supplies up to 22 Nm of static torque. The housing seats against mounting faces through a centering flange with a 110 mm diameter, which helps keep alignment accurate on gearboxes or direct-drive frames. Heat is removed by natural convection, so no forced airflow or liquid circuit is required around the motor. When energized, the rotor reaches a nominal speed of 3000 rpm, matching many standard gearbox ratios used in packaging and handling equipment. Because cooling is passive, nearby wiring and mechanical clearances are not shaped by a fan housing or liquid fittings.

The power conductors terminate through a connector on side A, allowing right-hand cable routing in compact panels. For velocity feedback, the internal tacho produces 3 V/1000 rpm with a standard accuracy grade, while position data is delivered by an incremental encoder mounted in the same rear housing. This feedback arrangement gives the paired drive separate signals for speed regulation and position tracking. Keeping both feedback devices in one assembly reduces the need for separate mounting hardware around the back end of the motor. Copper windings follow the FS code, and the motor length C keeps the housing consistent with other MAC093 variants in the same frame class.
