Product Description:

The MAC112C-0-ED-4-C/130-A-0/WI524LV/S005 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Supplied as a motor for analog drives, it delivers precise torque and speed control to legacy or mixed-generation automation lines. The model carries the length designation C, which indicates an intermediate rotor stack that balances torque production with rotational inertia in standard industrial frames. This configuration supports controlled acceleration and stable operation when the motor is paired with a compatible servo amplifier.

The motor has no blocking brake, so applications that require shaft holding must add an external brake or rely on drive torque. Thermal dissipation depends on natural convection, so airflow around the housing must remain unobstructed. Mounting alignment is aided by a centering pilot of 130 mm, which helps position the motor accurately against a compatible machine flange. The rotor can reach a nominal speed of 3000 rpm when the servo amplifier supplies the required frequency and current. The stator uses winding code ED, which indicates the resistance and inductance values required by compatible MAC series power modules. Power is supplied through a single-ended connector on side A, simplifying cable routing within the machine frame. Position information is provided by a standard-mounted incremental encoder, while the integrated tachogenerator supplies proportional speed feedback to analog regulators.

The motor has a frame size of 112, providing a flange pattern suitable for medium-duty gearboxes and belt drives. Output torque is transmitted through a DIN 6885 keyway, which creates positive engagement between the shaft and hub without relying only on friction. This shaft interface supports secure coupling when the connected mechanism experiences changing torque during acceleration and deceleration. For velocity loops that use analog tacho inputs, the integrated generator delivers 3 V/1000 rpm at standard tacho quality. Its proportional voltage output allows the connected analog drive to detect speed changes and correct deviations during operation.
