Product Description:

The MAC071B-0-TS-4-C/095-A-0/WI511LV is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts command voltages from legacy control hardware into precise electromechanical motion for positioning and velocity tasks. The design targets general-purpose automation, packaging, and material-handling lines where closed-loop speed regulation and stable torque delivery are required. The motor interfaces with drive amplifiers that supply sinusoidal currents proportional to error signals.

Mechanical alignment is set by a centering seat of 95 mm, allowing repeatable concentric mounting to gearboxes or machine frames. Heat produced in the stator is removed by natural convection, so no external fan or liquid cooling infrastructure is needed. The rotor is rated for a nominal speed of 3000 min⁻¹, which is the synchronous operating point used by the analog velocity loop. Power conductors exit through a single plug at a connector on side A, simplifying cable routing inside cabinets. A built-in tacho generator delivers 3 V/1000 min⁻¹; this signal feeds the drive so it can compare actual and command speed. For position tasks, the motor carries an incremental encoder with standard mounting that outputs square-wave channels for fine commutation and homing.

The TS winding code indicates the resistance and inductance values that the paired analog amplifier expects. The frame code 071 indicates the nominal stack diameter and matches the motor to moderate-inertia loads. Because the unit is supplied without a blocking brake, holding torque must be provided by the drive or an external mechanical lock when power is removed. The length designation B keeps the overall housing compact for restricted mounting envelopes, and the standard tacho quality supports the speed feedback linearity needed for tight proportional-integral control during slow-speed indexing.
