Product Description:

The MAC063C-0-MS3-C/095-B-0 is a compact servo unit produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it is installed on machinery that relies on continuous-signal amplifiers rather than fully digital inverters. By converting commanded current into proportional torque, the unit provides precise velocity and position control for automated packaging stations, pick-and-place gantries, and small transfer lines.

Mechanical and electrical limits define its working envelope. A nominal shaft speed of 3500 min⁻¹ establishes the maximum synchronous velocity attainable without oversaturation. Continuous stall capability is rated at 2.1 Nm, giving the axis enough holding force for static loads when motion is halted. Each ampere delivered by the amplifier produces approximately 0.51 Nm/A of torque, a ratio that simplifies current loop tuning. For transient acceleration, the drive can supply a peak pulse of 22 A, allowing short bursts of extra torque before thermal limits are reached. Those limits are moderated by a thermal time constant of 30 min, indicating how long the winding temperature takes to climb toward steady-state when load conditions change.

Dynamic behavior is influenced by a rotor inertia of 4.0 × 10⁻⁴ kg·m²; this low mass lets the axis follow rapid command changes with minimal lag. Electromagnetic response is characterized by a winding inductance of 3.2 mH, which filters current ripple, and a winding resistance of 2.8 Ω, setting copper losses under load. Heat produced by those losses is removed solely through Natural convection, so installation must leave sufficient airflow around the housing. The power connector is positioned on side B, and the 95 mm centering diameter aligns the flange precisely with gearboxes or mounting plates.
