Product Description:

The MAC090C-0-GD-1-B/110-A-0/I625 servo unit is produced by Bosch Rexroth Indramat and forms part of the MAC AC Servo Motors series. Designed for use with proportional current commands from analog servo amplifiers, the motor translates them into controlled rotary output. In automated presses, textile frames, and packaging lines, it supplies repeatable motion so mechanical stages can reach commanded positions with consistent accuracy during continuous operation. Its operating concept suits current-controlled servo systems that rely on the external amplifier for regulation functions.

The flange includes a 110 mm centering diameter that aligns the motor face with couplings and helps prevent radial misalignment under load. Thermal energy is removed through natural convection, allowing installation without ducted air or an auxiliary fan. Electromagnetic behavior is linked to the GD winding code, which corresponds to resistance and inductance values used by compatible analog drives in this frame size. Rotor position is reported through incremental encoder feedback, giving the controller finely spaced pulses that support both velocity and position loops. Power and signal leads exit through a plug-style connector, which keeps cable bends outside the machine envelope and helps preserve routing space around the axis.

As a motor for analog drives, this MAC090C variant accepts sinusoidal current from legacy transconductance amplifiers without a digital interface. The unit is supplied without a blocking brake, so any holding force at standstill must come from external hardware or continuous drive current. Cable management is simplified by the dedicated connector on side A, which keeps power and feedback terminations on one face of the housing. This arrangement helps when the motor is mounted close to guards, brackets, or other machine elements that limit access around the rear of the axis.
