Product Description:

The MAC112C-0-ED-2-C/130-A-0/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. As a motor for analog drives, it supplies controlled torque and speed to axes that rely on analog velocity or current loops for positioning tasks on machine tools, printing presses, and material-handling equipment. Its electromechanical design supports fast acceleration and stable running, integrating into legacy control platforms where digital fieldbus communication is not required. The motor couples directly to gearboxes or loads through a keyed shaft to transmit precise motion under closed-loop control.

The frame corresponds to 112 size classification, giving a stator outside diameter compatible with common IEC flange patterns. With the length code C, the active magnetic stack is extended to raise continuous torque without altering the mounting pilot, which remains 130 mm in centering diameter. The designated winding code ED sets the phase resistance and inductance so that standard analog amplifiers can regulate current without saturation. Under rated excitation, the rotor reaches a nominal speed of 3000 rpm, enabling mid-range linear feeds while keeping windage losses within safe limits. This combination supports stable operation in machinery that uses analog MAC motor control.

Thermal management relies on natural convection, so unobstructed airflow around the ribbed housing must be maintained during continuous duty cycles. The power conductors enter through a connector on side A, allowing the motor to be mounted in tight spots without bending high-current cables around the rear flange. Rotor speed is reported by tacho feedback of standard quality, and the built-in generator produces 3 V/1000 rpm, a signal level recognized by legacy analog velocity loops. Because a blocking brake is not present, the drive must apply holding current or an external clamp whenever vertical loads need to stay fixed after shutdown.
