Product Description:

The MAC071C-0-US-3-C/095-A-0/S001 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is identified in plant documentation as a motor for analogue drives, and it supplies closed-loop torque and speed control to automated machinery that relies on precise positioning. Integrated tachofeedback on a second shaft end provides the velocity signal required by legacy drive amplifiers.

The rotor is located with a 95 mm centering diameter, allowing drop-in interchange with gearboxes or mechanical mounts that share this pilot bore. Heat is removed through natural convection, so no external blower or liquid circuit is required. During continuous operation the shaft is rated for 2000 min⁻¹, a speed matched to medium-inertia loads and the bandwidth of analogue regulators. The built-in tacho generator outputs 3 V/1000 min⁻¹; this proportional voltage serves as the feedback reference for the drive card and is produced to a standard accuracy class. Windings identified by code US establish the motor’s resistance, inductance, and thermal limits, ensuring correct pairing with factory-specified power modules. Tacho quality is declared as standard, indicating normal ripple and linearity for general motion tasks.

The mechanical envelope follows MAC frame code 071, and the active core follows length designation C, giving the motor its overall torque density and mass. Power conductors exit through a keyed connector on side A, simplifying cable routing in cabinets where adjacent drives are stacked vertically. A blocking brake is Not Present, so holding torque must be supplied by the drive or by an external clamp when power is off. The feedback configuration includes tachofeedback with a second shaft end, making the unit compatible with resolver-less analogue control loops and allowing a user-mounted encoder or mechanical load on the opposite end.
