Product Description:

The MAC071C-1-US-4-C/095-B-0/DI517LV belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It is defined by the manufacturer as a motor for analogue drives, and in automated machinery it delivers commanded torque and speed to axes that rely on analog velocity or current loops. The unit is supplied without a blocking brake, so any static load-holding is handled by external mechanical means or continuous drive current.

This model uses an integrated blower that operates from a supply of AC 230 V; the air moves along the housing fins to support the specified axial surface cooling method. A centering diameter of 95 mm fits standard mounting plates while keeping the rotor precisely aligned. The motor reaches a nominal speed of 2000 min⁻¹, a value balanced to its magnetic design and thermal limits. Frame designation motor size 071 places it in the medium torque range of the series, and the winding characteristics coded as US match this speed with the required current and voltage profile.

Physical length is identified by motor length C, giving the active stack depth that determines continuous torque capacity. Power enters through a connector on side B, simplifying cable routing inside tight enclosures. For velocity feedback the tacho generator delivers 3 V/1000 min⁻¹ and carries the manufacturer’s standard accuracy grade, while position data comes from a incremental encoder with shock-damped mounting that resists vibration. An alternative feedback configuration allows tachofeedback to be paired with either incremental or absolute encoders when finer resolution is necessary. Together these characteristics let the analogue drive close speed and position loops with predictable thermal behavior and consistent signal quality.
