Product Description:

The MAC063C-0-MS-4-C095 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As a torque-generating component for industrial automation, the unit interfaces with analog drive controllers to supply precise rotational movement to machine axes, pick-and-place modules, and packaging lines. The design combines permanent-magnet excitation with electronic commutation so that velocity and position can be regulated by the drive based on feedback supplied by sensors integrated into the motor housing.

Cooling is provided by natural convection. Heat is transferred through the aluminum stator casing without fans or external liquid circuits, so mounting space and maintenance demands remain low. The compact frame uses the MAC family’s size 063 footprint and the elongated length C stack, which helps balance quick acceleration with moderate inertia. Under rated supply conditions, the shaft reaches a nominal speed of 3500 rpm, giving the connected drive a mid-range velocity band suitable for indexing tables or light tooling spindles. A built-in tacho generator produces 1.5 V/1000 rpm, so the controller receives real-time speed information without relying only on digital encoder data.

For higher-resolution feedback loops, the motor also supports tacho feedback with an incremental or absolute encoder through the same rear cover arrangement, allowing signal formats that match older and newer amplifiers. Electromagnetic behavior is set by winding code MS, which matches the phase resistance and inductance used for the MAC063 torque class. Because it is a motor for analog drives, the power connectors and sensor leads follow pin assignments used across earlier Rexroth controller generations. Motion accuracy also benefits from standard tacho quality, which helps keep speed ripple within limits for assembly and material-handling stations.
