Product Description:
The MAC063C-0-MS-3-C/095-A-1 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it delivers controlled mechanical power to machine tools, packaging stations, and handling systems that use continuous-signal amplifiers rather than fully digital controllers. Its feedback loop allows the drive to monitor shaft speed directly and regulate acceleration and steady-state velocity during automated production cycles.
This model reaches a nominal speed of 3500 rpm, providing a high rotational rate for positioning and speed-controlled applications. Heat produced by the stator is dissipated through natural convection, so no external blower or liquid-cooling circuit is required. The installation must permit unobstructed airflow around the housing to support effective heat dissipation during continuous operation. A blocking brake rated at 3 Nm holds the shaft when power is removed, preventing load drift on vertical or overhung axes. Mechanical alignment with gearboxes or mounting surfaces is guided by a 95 mm centering diameter, which supports concentric assembly and limits radial runout. Power conductors enter through a connector on side A, simplifying cable routing when the motor flange faces the driven equipment.
The feedback assembly includes tacho feedback and a second shaft end, allowing an external encoder or fan to be coupled without changing the primary drive interface. At rated speed, the built-in tachogenerator produces 1.5 V/1000 rpm, supplying the analog drive card with a velocity signal proportional to shaft speed. The frame size of 063 establishes the motor’s stator cross-section and compatible bolt pattern. Winding code MS identifies the copper fill and electrical resistance selected for this speed and torque range. Motor length index C indicates the active stack depth that works with the winding to provide continuous torque for medium-duty positioning tasks.
