Product Description:

The MAC071A-0-ES-3-C/095-B-0/S001 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it supports closed-loop motion control on positioning tables, pick-and-place axes, and other industrial automation equipment that relies on velocity and torque commands from legacy amplifiers. Because it is intended for analog control architectures, it fits systems that use command voltages rather than digital network control. The housing, magnetic stack, and integrated tachogenerator work together to give the drive continuous speed feedback, helping commanded velocity stay stable as load changes during operation.

The mechanical interface includes a centering diameter of 95 mm, which aligns the motor concentrically with adjacent machine frames and helps support accurate coupling alignment. Heat is removed by natural convection, so the cooling surfaces need open air around them for proper thermal dissipation during continuous use. During operation, the rotor reaches a nominal speed of 4000 rpm, which sets the standard running speed expected from the matching drive output. Power is delivered through a connector on side B, which can simplify cable routing when several motors are mounted on the same machine plane. The integrated tacho produces 1.5 V/1000 rpm, giving the control amplifier a proportional voltage signal for speed regulation without a separate encoder interface.

The feedback chain is completed by tacho feedback routed through a second shaft end, allowing additional velocity monitoring in precision axes that depend on stable analog speed information. The motor is supplied without a blocking brake, so any required holding torque must come from external clamping hardware or controlled drive torque when the axis is stopped. Winding code ES identifies the electrical winding used for this motor and matches it to compatible analog drives. Frame size 071 identifies the motor's stator cross-section, while the A length keeps the housing compact for installations with limited axial space around guards, couplings, or adjacent machine elements.
