Product Description:

The MAC071C-0-US-4-C/095-B-1/WI517LV/S001 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. As a motor for analog drives, it converts ±10 V reference signals into commanded shaft motion, supplying precise torque and speed to axes in machine tools, handling modules, and other automated equipment that require closed-loop positioning. Integrated feedback allows the paired drive to correct motion deviations quickly during acceleration and low-speed positioning. The compact 071 frame simplifies integration into multi-axis assemblies where space is limited, and it suits applications that require precise starts and stops in compact machine layouts.

The motor uses a centering flange diameter of 95 mm to align the housing to gearboxes or machine frames. Shaft torque is held during power-off periods by the integrated blocking brake rated at 3 Nm, so the motor can maintain position when the axis is stopped. Heat is removed by natural convection, eliminating forced cooling hardware and keeping installation simple. The keyed output shaft follows the DIN 6885 keyway profile for direct coupling with drive hubs. Nominal speed capability reaches 2000 rpm, which suits the inertia class of the MAC071 frame and supports steady operation across typical servo duty cycles. Power leads exit through a connector on side B, so cabling remains on the non-drive end.

Signal processing is handled by tacho feedback that delivers 3 V/1000 rpm and by an incremental encoder with standard mounting. This combination supports velocity and position loops on analog drive controllers and maintains stable motion feedback during commanded speed changes. Motor size code 071 pairs with winding designation US, identifying the electrical characteristics expected by the current regulator. Standard tacho quality supports repeatable voltage output, which helps the drive maintain consistent speed regulation during continuous operation.
