Product Description:

The MAC090B-0-JD-4-C/110-A-1/WI524LV belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. This eight-pole AC servo motor is intended for integration with closed-loop servo amplifiers, where it converts commanded current into precise shaft torque for positioning or velocity control in automated machinery. Its flange dimensions match the 090 frame size used across the series, allowing installation in machine layouts that use existing MAC mounting dimensions.

The motor seats against a mounting pilot with a 110 mm centering diameter, allowing repeatable alignment within housings, couplings, and gear stages. Heat generated by copper losses is dissipated solely through natural convection cooling, eliminating the need for auxiliary blowers in sealed cabinets or enclosed machine spaces. Power conductors terminate through a connector on side A, simplifying cable routing along the machine frame and reducing congestion near the rear housing. A standard blocking brake holds the shaft when power is removed, helping prevent back-driving on vertical axes or other load-bearing positions. Rotor speed feedback is provided through tachofeedback, giving the drive continuous velocity information for closed-loop regulation across the normal operating range.

For position loops, the unit relies on an incremental encoder with standard mounting, producing quadrature signals compatible with common analog interface cards. Because it is a motor for analog drives, current and tacho signals are handled directly by proportional controllers rather than by digital network interfaces. The standard tacho quality rating indicates the permissible ripple and linearity of the velocity signal, supporting stable low-speed operation without excessive filtering. This configuration suits compact servo axes that require passive cooling, integrated feedback, and dependable motion control in presses, pick-and-place units, and tool-changing mechanisms.
