Product Description:

The MAC112C-0-ED-4-C/130-A-1/WI520L/S05 is an AC servo motor developed by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. As a motor for analog drives, it converts sinusoidal drive currents into controlled mechanical rotation for positioning and velocity control tasks in automated machinery and handling equipment. The unit integrates with legacy analog amplifiers and provides dynamic torque for feed axes, indexing tables, and similar motion applications in industrial automation lines. Because it works with analog drive technology, it is also suitable for retrofit machines that must remain compatible with existing control architecture and established feedback methods.

In mechanical terms, the motor includes a blocking brake rated at 45 Nm, giving sufficient holding force for vertical loads when power is removed. Shaft alignment with the machine frame is set by a 130 mm centering diameter, which matches the standard flange pattern of the MAC size class. Thermal dissipation relies on natural convection, so no external blower or liquid circuit is required. Under rated excitation, the rotor reaches 3000 rpm, a nominal speed suited to mid-range feed axes. The tachogenerator produces 3 V/1000 rpm, and the winding code ED indicates the electrical design used with compatible drive modules.

The motor has frame size 112, which provides a practical balance between rotor inertia and continuous output for medium payloads. Position data is returned through an incremental encoder mounted in the standard location, allowing the analog controller to compare pulse-based position information with tacho feedback for tighter loop accuracy. For streamlined wiring, the three-phase power conductors exit through a connector on side A, keeping cable routing consistent on the drive side of the machine. This arrangement helps maintain orderly cable paths near slides, belts, or rotary tables that cycle repeatedly during normal operation.
