Product Description:

Bosch Rexroth Indramat manufactures the MAC090C-0-GD-4-C/110-A-2/WI521LV/S013 servo motor as part of the MAC AC Servo Motors series. This brushless unit converts drive-amplifier current into controlled rotary motion for positioning tables, pick-and-place heads, and other automated axes. In industrial applications, it pairs with analog drives to supply closed-loop torque and speed, providing a compact torque source for many motion stages. Its brushless design supports repeatable motion in automated equipment where stable response and low routine maintenance are important.

A heavy-duty blocking brake is integrated so the shaft can hold position when power is removed, which is useful for vertical loads or indexing fixtures. The mounting pilot has a centering diameter of 110 mm, allowing direct coupling to frames that use this centering size. Heat produced by copper losses moves to ambient air through natural convection, so the motor installs without forced-air ducts when ambient airflow is unobstructed. Power is fed through a plug positioned at the drive end, and the connector on side A keeps the cable run parallel to the housing and away from moving parts. The GD winding sets the resistance and inductance used with compatible MAC family amplifiers for medium-inertia axes.

The unit is classified as a motor for analog drives, which means command signals are supplied as continuous voltage or current rather than serial packets. Speed verification relies on standard tachometer quality, which is suitable for general-purpose positioning without high-resolution tracking. For position loops, the housing carries an incremental encoder with standard mounting, producing quadrature pulses that align with common resolver-to-digital converters. The wiring harness supports tachofeedback, incremental encoder, or absolute encoder signals for compatibility with different feedback arrangements. These feedback paths allow the connected drive to monitor both shaft speed and position during routine servo operation.
