Product Description:

The MAC093B-0-OS-2-C/110-A-2 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for analog drives in industrial automation. The motor converts command voltages from legacy controllers into precise mechanical rotation for axes such as packaging machines and material-handling gantries. Because it is built for analog control architecture, it fits systems that regulate motion through voltage commands and continuous speed feedback.

This unit includes a heavy-duty blocking brake that can resist up to 14 Nm when power is removed, allowing vertical or indexing axes to remain fixed without external clamps. A centering diameter of 110 mm aligns the stator housing with gearboxes or machine frames and helps keep the output shaft concentric with the driven mechanics. Under rated excitation, the rotor reaches 2000 rpm, which suits mid-range positioning tasks that require steady torque with limited overshoot. Heat generated by copper losses is removed through natural convection, eliminating the need for fan power or liquid cooling channels. Cooling through the housing surface also keeps the motor suitable for installations where simple airflow management is preferred.

Winding code OS identifies the coil impedance used by the matching analog amplifier. The tacho generator produces 3 V/1000 rpm, giving the controller a consistent velocity signal during closed-loop operation. Power leads exit through a connector on side A, and the signal conductors follow the same axial direction for orderly cable routing. This layout can help when the machine places cable carriers or connection space on the A side of the axis. The frame size is 093, and length code B indicates a mid-length rotor stack that balances inertia with rated torque. The motor uses tacho feedback rather than a digital encoder, so it remains compatible with analog speed-regulated installations.
