Product Description:

The MAC093B-0-OS-4-C/110-R-0/WI647BX is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drive systems, it converts controlled current into precise rotary motion for positioning, indexing, and speed regulation in automated machinery. When connected to a compatible amplifier, the motor forms the motion-producing half of a closed-loop axis and supports repeatable movement in assembly cells, packaging equipment, and process lines. Its integrated feedback arrangement allows the drive to monitor motion continuously during operation.

A centering shoulder of 110 mm gives the flange a repeatable locating surface for machine frames. Heat is removed by natural convection, so the installation area must allow free airflow around the housing. Under rated load, the rotor operates at 2000 rpm, which suits motion profiles that favor moderate speed with solid torque output. The winding code OS corresponds to resistance and inductance values used with analog servo amplifiers. A built-in DC tachogenerator outputs 3 V/1000 rpm, supplying proportional speed feedback for continuous regulation.

Frame designation 093 indicates the stator diameter, while length code B identifies the axial stack used for the motor’s torque range. Position feedback is provided by an incremental encoder mounted in standard alignment, and it works alongside the tachogenerator to support stable control during speed changes. Power is routed through a connector on the right side, which can simplify cable routing where lateral clearance is available. The unit is supplied without a blocking brake, so any holding function must come from the drive or an external mechanical device. This arrangement suits applications that do not need the motor to hold a load after power is removed.
