Product Description:

The MAC063A-0-ES-4-C/095-A-1/WI524LV/S001 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it is intended to power rotary axes in analog-controlled automation systems where precise torque and speed regulation are required. By combining permanent-magnet excitation with electronic feedback devices, the unit converts drive commands into controlled mechanical rotation for positioning tables, gantries, and feed spindles. Its operating concept supports repeatable response during starts, stops, and speed changes in closed-loop motion tasks.

The frame follows size code 063 and length code A, giving a compact profile suited for light to medium loads. Inside this frame, winding code ES establishes the electrical characteristics expected by the matching analog drive. Under rated conditions, the shaft reaches 3500 rpm, allowing rapid cycle times without overspeeding the rotor. Heat from copper losses leaves the housing by natural convection, so no external blower or liquid circuit is necessary. A centering shoulder of 95 mm aligns the flange to gearboxes or machine plates, and the power leads exit through a connector on side A for easier cable routing in tight cabinets. Because cooling is passive, surrounding machine space remains simpler and airflow management in the installation is less demanding.

A standard blocking brake applies 3 Nm of holding torque to prevent drift when power is removed. Output torque is transmitted through a shaft machined with a DIN 6885 keyway, giving positive engagement with pulleys or rigid hubs. Rotor motion is monitored by a tachogenerator that produces 1.5 V per 1000 rpm, and an incremental encoder in the standard position supplies digital counts for speed or position loops. The feedback assembly includes tacho feedback and supports either incremental or absolute operation, while the standard tacho quality suits general-purpose accuracy requirements. This combination allows the drive to monitor both motion stability and holding behavior during normal axis operation.
