Product Description:

The MAC63C-0-MS-2C/95-A0/S001 AC servo motor is produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive systems in industrial automation, it converts electrical energy into precisely regulated torque and speed for pick-and-place axes, printing cylinders, and light material-handling stages. The unit lacks an internal blocking brake and relies on natural convection for heat removal. Integrated tacho feedback reports shaft velocity so the analog controller can modulate current in real time.

The motor draws a continuous stall current of 4.1 A; this steady-state value indicates the current that the drive must supply when the rotor is locked and rated torque is required without overheating. The locked-rotor torque reaches 2.1 Nm, allowing the axis to hold loads against gravity or process forces while stationary. During normal motion, the rotor can spin up to 3500 rpm, a speed suitable for medium-throughput machinery without additional gearing. Electromechanical performance is influenced by a torque constant of 0.51 Nm/A, meaning each ampere of armature current produces approximately half a newton-meter of torque. Dynamic control behavior is also shaped by the phase winding inductance of 3.2 mH, which limits current ripple and helps the amplifier maintain smooth torque at high switching frequencies.

Electrical losses produce heat that must be managed over a thermal time constant of 30 min, which is the interval required for the stator to reach 63% of its final temperature after a load change. Copper losses are affected by a phase resistance of 2.8 Ω, allowing power dissipation to be calculated during continuous operation. Mechanical response is influenced by a rotor inertia of 4.0 × 10⁻⁴ kg·m², offering a balance between quick acceleration and stable velocity tracking. The motor has an overall mass of 4.6 kg, which keeps moving weight low for gantry or robot joints. Its rigid keyway shaft provides a secure mechanical interface for connected components.
