Product Description:

The MAC093B-0-OS-2-C/110-A-0/S005 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drive systems, it converts regulated current from matched amplifiers into controlled mechanical rotation used for positioning axes, conveyor sections, and similar automation tasks. The motor integrates tachometer feedback so the drive can monitor speed in real time and correct deviations, providing closed-loop performance expected in production machinery.

At the mechanical interface the flange provides a centering diameter of 110 mm, aligning the shaft precisely with gearboxes or load couplings. The winding set identified by OS is engineered for medium inertia loads and pairs with the B length housing, setting both thermal capacity and torque constant. Under rated conditions the rotor turns at a nominal speed of 2000 min⁻¹, a value monitored by the internal tachometer that produces 3 V per 1000 min⁻¹ for the control loop. Heat generated during duty cycles is removed solely by natural convection, so airflow around the motor frame must not be obstructed. Tacho quality is noted as standard, which matches general-purpose velocity regulation requirements without additional linearization circuitry.

The frame coded as 093 defines the stator diameter and sets overall torque potential while keeping installation dimensions compatible with common machine frames. Speed information reaches the drive through tachofeedback, eliminating the need for external encoders and simplifying cable sets. For applications that rely on dynamic axis holding during power-off, designers should note that a blocking brake is not present, so mechanical clamps or powered holding must be provided externally. Power conductors enter through a connector on side A, which positions the cable away from adjacent axes and eases routing inside compact electrical enclosures.
