Product Description:

The MAC063-A-0-RS-2-C is a compact AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive systems, it converts analog command voltages into precise shaft rotation for indexing tables, pick-and-place modules, and other position-controlled axes. Heat produced in operation is removed by natural convection, so the motor installs without additional fans. Its compact format suits space-limited machine assemblies where separate cooling hardware would be undesirable. Its sealed construction allows direct mounting in automated equipment located up to 1000 m above sea level.

The motor has a nominal speed of 6000 rpm, enabling high cycle rates when paired with suitable gearing. At zero speed, the rotor can oppose load moments with 0.8 Nm while consuming a standstill current of 3.5 A. A torque constant of 0.230 Nm/A links drive amplifier current to delivered torque. The motor windings have an inductance of 3.5 mH, which helps smooth current changes during servo operation. Tacho feedback generates 1.5 V per 1000 rpm, providing the analog drive with continuous velocity information for closed-loop regulation.

Short bursts of load acceleration are supported by a peak pulse current of 19 A, giving the drive headroom for fast indexing that exceeds continuous ratings. A rotor inertia of 2.4 × 10⁻⁴ kg·m² balances responsiveness with rotational stability, minimizing overshoot during rapid reversals. Thermal saturation develops slowly thanks to a thermal time constant of 30 min, so intermittent duty cycles rarely demand external cooling. The housing meets IP65 requirements, allowing exposure to airborne dust and low-pressure water jets, while a winding resistance of 3.7 Ω and a total mass of 3.2 kg support stable heat distribution and straightforward installation.
