Product Description:

The MAC071C-0-US-4-C/095-A-0/WI527BX/S001 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is intended for analog drive packages where precise velocity and position control are required in industrial automation cells, pick-and-place stations, and indexing tables that depend on repeatable starts and stops. The motor’s electromechanical design supports direct coupling to matched drives so closed-loop control can be maintained without intermediate gear stages, which helps preserve response and positioning accuracy at the axis.

The rotor seats against a centering pilot of 95 mm, allowing accurate alignment to machine frames and minimizing radial runout. Heat produced in the stator is dissipated by natural convection, so no external blower or liquid circuit is needed. Under rated conditions, the shaft reaches 2000 rpm, supplying responsive speed regulation for motion profiles common in assembly equipment. Torque is transferred through a shaft with a DIN 6885 keyway, ensuring positive engagement with couplings or pulleys during reversing motion. The motor has size code 071, placing it in the mid-range of the MAC family and balancing continuous torque capability with compact mass.

This model is supplied with no blocking brake, so static holding must be provided by the drive or by external clamps. Commutation and velocity feedback are delivered by a tacho that generates 3 V/1000 rpm, and position data comes from an incremental encoder mounted in the standard location behind the shaft. This arrangement allows the drive to track motor speed and shaft position during routine motion control. Winding code US indicates the copper fill and electrical resistance used with compatible drive modules, and power enters through a single connector on side A to simplify cable routing in compact control cabinets.
