Product Description:

The MAC025B-0-ZS-4-E/040-B-1/WI656LV/S001 belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It is an AC servo unit intended to deliver precise torque and velocity control in automated machinery that still relies on analog drive amplifiers. Within such loops, the motor converts command voltages into exact shaft rotation, making it suitable for pick-and-place axes, indexing tables, and other motion points that must synchronize with older but serviceable control hardware. This also makes it practical for installations that retain established analog motion architecture.

A blocking brake is supplied as a standard feature, so the shaft remains fixed when power is removed and vertical or cantilevered loads do not drift. Heat is removed through natural convection, eliminating the need for forced-air components and helping keep the surrounding layout simple. The windings are arranged for tacho feedback and are compatible with incremental or absolute encoder systems, giving the drive a direct speed reference during acceleration and deceleration. Length code 025 indicates a short stator stack that minimizes overall depth, while frame size B sets the flange and pilot dimensions that match standard gearboxes of the same class. Mains power reaches the stator through a connector on side B, keeping high-current conductors on the rear of a machine frame and separating them from feedback cabling.

This motor is classified for analog drives, so its voltage constants and current ratings align with ±10 V command cards rather than fieldbus-based servo controllers. When used with an incremental encoder mounted in the standard position, the drive can close the loop on 1Vpp or TTL signals for fine positioning without additional adapters. That feedback arrangement supports stable speed regulation as well as precise stop positioning during repeated cycles. The housing, brake mechanism, winding insulation, and connector seals are suited for continuous-duty factory environments.
