Product Description:

The MAC112D-0-ED-4C/130-A2/WI520/S013 is an AC servo motor built by Bosch Rexroth Indramat for closed-loop motion axes that rely on precise velocity and torque regulation. It belongs to the MAC AC Servo Motors series and is intended to interface with analog controllers that supervise speed and current. Within automated machinery, the unit converts drive commands into mechanical rotation so that positioning tables, packaging heads, or material-handling spindles follow exact cycle profiles. Its operating concept suits repeatable axis motion where smooth response is needed during frequent starts, stops, and speed changes.

Thermal exchange for this motor is handled by natural convection, so heat leaves the housing through surface radiation and airflow without auxiliary fans. The feedback system includes tacho feedback signals that let the drive monitor real-time speed deviations. A frame code of 112 identifies the stator diameter and the related flange dimensions used with this motor size. During continuous duty, the shaft can sustain a nominal speed of 3000 rpm, which fits many common servo applications. Electromagnetic behavior is influenced by the ED winding code, and this winding affects the voltage constant and rated current so acceleration and thermal rise remain within the intended operating range.

The motor uses the standard housing format but extends the active stack to the specified D length, increasing copper mass for higher continuous torque without changing the mounting pattern. It is a motor for analog drives, so command inputs are handled as ±10 V references rather than serial fieldbus messages. This arrangement supports integration with legacy amplifier racks that still use analog signal control. An optional absolute encoder can provide position capture after power loss, allowing the axis to reference position more quickly at startup and reducing dependence on external limit switches.
