Product Description:

The MAC093B-0-GS-4-C/110-B-0/WI520/S01 is an AC servo motor produced by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. Designed for analog drive systems, the unit transforms electrical current into controlled mechanical motion so that machinery can follow precise speed and position commands in automated production lines. Its electromagnetic construction matches drives that rely on analog velocity or torque loops, making it suitable for tasks such as indexing tables, packaging axes, and material-handling gantries where repeatable acceleration is required.

The motor mounts through a centering pilot of 110 mm, allowing repeatable alignment with gearboxes and couplings while also establishing the reference for the shaft seal. Internal losses are removed by natural convection; no fan or liquid circuit is included, so cabinet airflow must keep the housing below its rated temperature. Under rated excitation, the rotor reaches 4000 rpm, a base speed that balances torque output and drive voltage in high-throughput workstations. The motor has no holding brake, so static loads must be held by the drive or an external clamp. Winding code GS indicates the phase resistance and inductance used by compatible analog drives for the correct current profile. The mechanical stack depth corresponds to motor length B, giving the rotor an inertia that suits medium-inertia loads without overshoot.

The power terminals are collected in a plug located on connector on side B, simplifying cable runs when the motor is installed with its shaft facing the operator. Motion feedback follows the WI520 configuration and includes a tacho generator together with an encoder. For velocity loops, the tacho produces 1.5 V per 1000 rpm at standard calibration quality, providing a linear voltage that the drive interprets directly. Position information is delivered by an incremental encoder fitted with the usual mounting pattern, so retrofit to existing Rexroth drives is straightforward. The frame is classified as size 093, and this envelope determines the flange geometry, bolt circle, and shaft dimensions used throughout the MAC family.
