Product Description:

The MAC025A-0-WS-2-E/040-C-0 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. The unit operates as a rotary actuator in industrial automation, receiving velocity and torque commands from drive electronics and converting them into precise shaft rotation for material-handling devices, pick-and-place axes, or light-duty machine tools. Its electromechanical design supports closed-loop positioning where stable speed tracking and rapid response are required to keep multiple machine axes synchronized during production cycles. This layout is well suited to compact motion tasks that need repeatable starts, stops, and smooth low-speed operation.

Heat is removed through natural convection, so the housing needs adequate airflow but no external fans or liquid circuits. Rotor speed is monitored by internal tachometer feedback that returns an analog voltage proportional to rpm, allowing classic velocity loops to correct load-induced error. The compact A frame size reduces mass and eases installation in space-limited machine sections or gantry arms. Electromagnetic properties follow the WS winding code, matching coil resistance and inductance to legacy power stages that deliver the correct current without saturation. The motor has no holding brake, so the shaft must be secured by an external brake or mechanical lock when power is removed.

The active magnetic stack corresponds to a 025 motor length, which supports the torque range available from this convection-cooled housing. As a motor for analog drives, it pairs with earlier transconductance amplifiers that rely on analog speed signals rather than digital encoder data. This arrangement supports installations that still use established analog control platforms and need a compatible motor with familiar response characteristics. The housing and shaft arrangement remain consistent with adjacent frame sizes, which helps when the motor is fitted into existing machine layouts or matched with similar axes.
