Product Description:

The MAC071C-0-US-2-C/095-B-1/S001 is an AC servo motor produced by Bosch Rexroth Indramat and part of the MAC AC Servo Motors series. Intended for analog drive systems, the unit supplies controlled rotary motion to machinery that relies on voltage-commanded positioning and speed loops. It combines the US winding, a C-length housing, and an integrated blocking brake in one assembly for automated production equipment. This design is suited to legacy motion platforms where the servo amplifier handles the control loop externally rather than inside the motor.

The mechanical interface uses a centering diameter of 95 mm, allowing accurate shaft alignment with gearboxes or direct-coupled loads. Under rated conditions, the rotor turns at 2000 rpm, a speed that matches the response range of analog position controllers used on transfer lines. The fitted brake supplies 3 Nm of holding torque so vertical axes can remain fixed when power is removed. Heat is dissipated through natural convection, eliminating the need for external fans or liquid circuits. Position and velocity are reported by integrated tachometer feedback, which generates a proportional voltage for the drive electronics. Power cabling is routed through a connector on side B, which helps when multiple motors are mounted close together.

Dimensional coding identifies a motor size of 071 and a body length of C, a combination that balances inertia and torque for medium-weight loads. The tachogenerator outputs 3 V/1000 rpm, giving the analog controller a linear speed signal for closed-loop regulation. Because the speed signal is proportional, the connected controller can adjust output smoothly during acceleration, deceleration, and steady-state operation. The compact housing also helps the motor fit installations where mounting space is limited but stable speed feedback is still required in many retrofit applications.
