Product Description:

The MAC090B-0-JD-4-C/110-A-0/WI520LV is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for analog drives, it converts ±10 V velocity or position commands into controlled shaft motion for indexing tables, packaging stations, and light machining axes. Its 090 frame size offers a balance between torque output and inertia, helping the axis accelerate smoothly without requiring oversized mechanical transmission components. This operating style suits legacy motion systems that use an external amplifier to regulate speed and position. It can also be used on feed axes and rotary stations where repeatable response is more important than fully digital networking.

Its mechanical interface relies on a centering diameter of 110 mm, allowing direct flange mounting to compatible housings. Heat generated in the stator is removed through natural convection, so airflow around the motor body should remain unobstructed during operation. The three-phase supply enters through a plug-in connector on side A, which can simplify cable routing when access is limited at the rear of the machine. For position monitoring, the rotor uses an incremental encoder in the standard mounting location, providing two-channel pulse signals to the analog controller. Velocity feedback is complemented by a tachogenerator with standard tacho quality, which supports basic speed regulation in applications that do not require very fine feedback resolution.

The unit is delivered without a blocking brake, so vertical or heavily inertial axes need an external holding method when power is removed. Additional tachofeedback capability supports feedback processing in applications that need tighter speed regulation. Because it is configured for analog drives, setup relies on gain trimming rather than network-based parameter exchange. This makes the motor appropriate for systems that retain established analog control architecture while still needing encoder-based motion feedback. The motor remains part of the MAC AC Servo Motors family and is suited for mid-power axes in packaging, transfer, and light machining equipment.
