Product Description:

The MAC112C-0-HD-3-C/130-A-0 belongs to the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. It is supplied as a motor for analog drives, so velocity or torque commands are issued as continuous signals rather than through a fieldbus. In automated machinery, this motor delivers rotary motion to linear stages, spindles, or indexing tables and completes the feedback loop with the drive electronics to maintain commanded speed or position. It is commonly used on axes that need stable response from legacy motion systems.

A centering diameter of 130 mm aligns the flange precisely on the machine frame. The size 112 stator stack and the C length code give the motor its overall footprint and thermal mass. Heat is removed only by natural convection, making cabinet airflow or external fans unnecessary when ambient limits are met. Under rated excitation, the shaft reaches 2000 rpm, a nominal speed that balances torque density and bearing life for mid-range automation axes. Power conductors are routed through a connector on side A, which simplifies cable dressing in multi-axis panels. The built-in tachogenerator outputs 3 V/1000 rpm, and the analog drive uses this voltage to measure speed, while the standard tacho quality keeps ripple and linearity within normal limits for legacy control loops. This supports stable velocity feedback without requiring digital encoder processing.

The motor is delivered without a blocking brake, so any holding torque at standstill must be supplied by the drive or by an external brake module. An HD winding code indicates the resistance and inductance pair used with Indramat power stages that require higher current at lower voltage. Frame designation 112 provides a consistent mechanical interface across the MAC portfolio and supports the same mounting hardware. The feedback package combines tacho feedback and a second shaft end, allowing an auxiliary encoder, pulley, or handwheel to be added without coupling adapters for retrofit applications that need both speed feedback and rear shaft access.
