Product Description:

The MAC025B-0-ZS-4-E/040-L-0/WI671LV/S006 is a servo motor manufactured by Bosch Rexroth Indramat for use with legacy analog amplifiers. As a rotary actuator, it converts drive commands into controlled shaft rotation for printing, packaging, and general material-handling machinery. In machines that still use analog command structures, the motor responds quickly to changing reference values and supports repeatable motion. Its compact format suits installations that need fast response without taking up much machine space. The motor is intended for applications where reliable speed regulation and consistent positioning are needed without a large mechanical envelope.

Heat produced during operation leaves the frame through natural convection, so no auxiliary fan or coolant loop is required when free airflow surrounds the housing. Because cooling is passive, the motor can be installed in layouts that do not provide dedicated air or liquid services. The motor uses length code 025 and size B, which give it a compact mechanical envelope for direct coupling or gearbox mounting. This compact frame is useful where motors must fit close to guide rails, guarding, or neighboring axes. Three-phase power reaches the stator through a connector on the left side, which helps simplify cable routing when several motors are installed next to one another.

For speed control, the motor provides integrated tachometer feedback, and position signals are supplied by an incremental encoder with standard mounting located inside the rear cover. This arrangement gives the connected amplifier the feedback needed for stable velocity control and position tracking without external sensor hardware. Keeping the encoder inside the rear cover also avoids adding extra length to the motor body. The motor has no blocking brake, so vertical or overrunning axes need an external holding device or sustained drive torque after power removal. Classified as a motor for analog drives, this version of the MAC AC Servo Motors line is suited to retrofit and general automation tasks that require low inertia and stable feedback signals.
