Product Description:

The Bosch Rexroth Indramat MAC071C-2-NS-4-c/095-A-0/WI524LV/S001 is part of the MAC AC Servo Motors series. Designed as a motor for analogue drives, it interfaces with external servo amplifiers to deliver closed-loop motion in automated tooling, pick-and-place stations, and material handling lines. The 071 frame diameter and length code C keep the rotor mass low so acceleration is high, while the manufacturer integrates a balanced shaft to limit vibration across the full rated speed range. Its role in the automation cell is to translate regulated current into precise torque for axis positioning tasks.

Thermal management relies on Axial Surface Cooling driven by an auxiliary blower that runs on AC 115 V; this airflow moves parallel to the housing fins and allows continuous torque delivery without derating. Mechanical alignment to the machine frame is helped by a 95 mm centering diameter that positions the stator coaxially with the driven shaft. Power is transmitted through a spline shaft cut with a DIN 6885 Keyway, eliminating slip under cyclic loads. Under rated excitation the rotor can reach 3000 min⁻¹, giving the drive a speed constant compatible with many gear-free applications such as indexing tables.

For velocity feedback the motor carries a tacho generator that outputs 3 V/1000 min⁻¹, and positional data is supplied by an Incremental encoder mounted in the standard housing interface. This sensor set couples with the drive electronics to execute precise commutation because the three-phase winding follows the NS code for its electrical pitch and resistance values. Power conductors exit through a Connector to side A, simplifying cable routing in cabinets mounted on the left of the axis. The unit is built without a blocking brake, so holding force must be provided externally when power is removed.
