Product Description:

The MAC071A-0-ES-2-C/095-A-0 is an AC servo motor produced by Bosch Rexroth Indramat in the MAC AC Servo Motors series. It is intended for analog drive systems where precise electrical-to-mechanical conversion is needed to position loads or regulate speed on automated machinery such as pick-and-place stations and indexing tables. By combining a permanent-magnet rotor with integrated tacho feedback, the motor supplies the closed-loop control required for repeatable industrial motion. This arrangement makes the motor suitable for applications that need steady response during frequent starts, stops, and speed changes.

The mounting interface uses a centering diameter of 95 mm, allowing accurate shaft alignment against gearboxes or flanges. Thermal energy leaves the frame through natural convection, so no external blower or liquid circuit is required. The stator uses winding code ES, which sets the voltage and current relationship used with legacy analog amplifiers. Under rated excitation, the shaft reaches 4000 rpm, giving a balance between torque production and speed range for moderate-inertia loads. Power leads exit through a connector on side A, which helps guide cabling toward the drive cabinet in compact machine layouts.

The motor occupies size 071 in the MAC frame chart and extends to length code A, producing torque appropriate for mid-frame actuators without adding unnecessary installation depth. A built-in tachogenerator supplies velocity feedback; this configuration is identified as tacho feedback and delivers a proportional signal of 1.5 V/1000 rpm that the analog drive uses for speed regulation. This feedback helps the amplifier correct for load changes during acceleration and steady running. Tacho quality is standard, supporting stable control across the operating range. Because the unit is supplied without a blocking brake, any holding torque must be provided by the drive or by external mechanical holding when power is removed.
