Product Description:

The MAC071A-0-OS-2-C/095-A-1 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed as a motor for analog drives, it converts drive commands into regulated rotary motion for positioning tables, indexing stations, and similar automation tasks that require repeatable speed and torque. The motor is suited to machines that rely on smooth acceleration, repeatable deceleration, and accurate low-to-medium power axis control. Its integrated feedback and brake arrangement supports compact axis layouts where stable motion and controlled stopping are both required.

This model integrates a blocking brake rated at 3 Nm, allowing the shaft to hold load torque when power is removed. A centering flange of 95 mm aids precise alignment with gearboxes or machine frames. Heat is carried away by natural convection, so no external blower or liquid circuit is needed. Rotor position is monitored by built-in tacho feedback, which supplies an analog velocity signal to the drive for closed-loop speed regulation. The frame is identified as size 071, which gives the motor a compact envelope for medium-duty axes. Under rated excitation, the motor reaches 3000 rpm, matching drive outputs used in pick-and-place systems and light conveyor sections where rapid but controlled motion is required.

The power leads exit through a connector on side A, simplifying cable routing when the motor is mounted with the flange toward the machine interior. For velocity reference, the tacho delivers 3 V/1000 rpm, giving the controller a linear signal that scales directly with shaft speed. This arrangement helps the paired amplifier interpret speed changes during starts, stops, and reversals. Electrical characteristics correspond to winding code OS. Compatible drive settings must match this coil set so current limit and voltage gain remain appropriate for the motor.
