Product Description:

The MAC063C-0-MS-4-C-095-B-1-WI522LV is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is supplied as a motor for analog drives that translate ±10 V velocity or torque references into controlled rotation, allowing the axis to integrate into printing, pick-and-place, or light machining cells where coordinated motion is required. For digital position control, the motor includes an incremental encoder mounted in the standard location. It is used where steady velocity control and repeatable motion are needed on compact machine axes.

A standard blocking brake rated at 3 Nm secures the shaft during power-off or emergency stops, helping prevent unintended axis movement. The flange uses a 95 mm centering diameter to locate the motor concentrically on machinery, which helps reduce runout at the coupling. Thermal management relies on natural convection, so installation space must permit free air circulation instead of forced cooling. Passive cooling also avoids the need for a separate fan assembly around the motor body. Under rated winding excitation the rotor reaches 3500 rpm, supporting fast indexing cycles. Power conductors are attached through a connector on side B, which simplifies cable routing because signal feedback exits on the opposite face.

The electromagnetic core carries the MS winding code, which corresponds to the current density and torque constant used for this variant. That winding is built into the 63 mm frame envelope identified as 063, and the C-length stack adds active material for higher continuous torque without changing the front-face pattern. Speed feedback is generated by an internal tachogenerator that outputs 1.5 V/1000 rpm and uses standard tacho quality, so it provides a coarse signal for analog velocity loops. The encoder and tacho signals serve different control functions, which lets older analog amplifiers and newer motion controls use the same motor platform.
