Product Description:

The MAC093B-0-JS-4-C/110-A-2/WI518LV is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is designed for analog drive systems where tight velocity and position loops are required for automated machinery. By combining an internal tachogenerator with encoder feedback, the unit sends real-time speed and position data to the controller, allowing accurate motion in pick-and-place stations, feeders, and web-handling lines. That feedback arrangement helps the drive correct load changes quickly during repeated starts, stops, and short indexing moves.

A heavy-duty brake supplies 14 Nm of holding torque so vertical or suspended loads can remain stationary when drive power is removed or disabled. Shaft alignment during mounting is simplified by a 110 mm centering diameter that matches common flange patterns used on machine faces. Heat is removed through natural convection, eliminating the need for auxiliary fans where normal ambient airflow is available. The frame corresponds to motor size 093, and a nominal speed of 3000 rpm gives a useful balance between torque density and dynamic response in mid-range applications. Power conductors enter through a connector on side A, which keeps the cable exit direction consistent and helps routing stay clear of nearby tooling or guards.

A tachogenerator calibrated for 3 V/1000 rpm provides velocity feedback that the drive can use directly for analog speed control. Winding code JS indicates the electrical characteristics expected by compatible MAC analog amplifiers. Position data comes from an incremental encoder mounted in the motor housing, giving the controller the feedback needed for coordinated motion and repeatable stopping. The motor uses the B-length housing, which provides balanced rotor inertia for quick acceleration without excessive mass and helps the unit fit medium-duty axis layouts.
