Product Description:

The MAC090A-0-ZD-2-C/110 is an AC servo motor produced by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. As a motor for analog drives, it converts current-controlled commands from legacy velocity or position controllers into mechanical rotation. Systems that need precise speed regulation in packaging, printing, and material-handling loops use this model to drive load shafts, indexing tables, or traverse mechanisms during repetitive motion cycles. The motor mounts on standard B5 flanges and is intended for installation inside guarded machine areas on the machine frame.

Mechanical alignment is set by a centering diameter of 110 mm, allowing repeatable coupling to gearboxes, couplings, or mounting faces. Heat produced during operation dissipates through natural convection, so airflow around the housing must remain unobstructed. Rotor speed feedback is provided by tacho feedback, enabling the amplifier to close a velocity loop without an external encoder or separate sensing device. Under rated electrical excitation, the shaft reaches 1500 rpm, which suits medium-inertia loads that need stable speed rather than very high rotational output. Electromagnetic characteristics use winding code ZD, which indicates the winding arrangement used for this motor and helps match it to the intended amplifier range.

The unit expects analog current setpoints rather than digital fieldbus commands, which suits earlier control platforms and direct analog reference chains. The motor uses a standard tachogenerator, and its linearity and ripple remain suitable for steady speed regulation in conventional servo loops. At nominal speed, the tacho outputs 3 V/1000 rpm, a proportional signal the amplifier scales directly for real-time velocity correction. This arrangement lets the drive compare commanded and actual speed continuously during operation.
