Product Description:

The MAC063C-0-MS-4-C/095-B-1/WA612XX/S01 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for closed-loop motion axes where precise velocity and position control are required in factory automation. By combining a synchronous permanent-magnet rotor with electronic feedback devices, the unit converts electrical power into controllable rotary motion for machine tools, packaging stations, and automated handling modules.

An integrated blocking brake rated at 3 Nm holds the shaft when power is removed, and the brake is included in the standard configuration of this model. Continuous operation is cooled by natural convection, eliminating the need for external blowers. The motor reaches a nominal speed of 3500 rpm, allowing rapid cycles while remaining within thermal limits. Mechanical alignment to adjacent gearboxes is aided by a centering diameter of 95 mm. Rotor speed feedback is provided through a tacho generator that outputs 1.5 V/1000 rpm, and the feedback arrangement can support either incremental or absolute encoders for position control. Tacho quality is classified as standard, matching the accuracy required by analog velocity loops.

The electromagnetic behavior of the winding set marked MS affects current ratings, while the stack length code C indicates a longer active section that increases continuous torque without changing the frame footprint. Power leads are brought out through a connector on side B, simplifying cabinet cable routing when the motor is installed with the drive downstream of the mechanical load. As a motor for analog drives, it mates directly with Indramat transconductance amplifiers that reference the attached tacho signal. An attachment set for position feedback can be added when the application requires full servo positioning.
