Product Description:

The MAC025B-0-ZS-4-E/040-B-0/WI668LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. It is intended for legacy analog drive systems in which a ±10 V command or a similar reference signal is converted into controlled rotary motion for positioning tables, feeders, and auxiliary axes on automated equipment. The motor is suited to applications that need stable speed regulation and compact installation space. Its control concept is centered on conventional analog drive hardware rather than digital fieldbus-based motion control.

Heat is removed solely by natural convection, so the finned housing releases thermal energy to the surrounding air without an added blower or liquid circuit. Power enters through a connector on side B, which helps route the cable away from the machine face in compact layouts. The total axial build corresponds to motor length 025, giving the unit a short overall package. Velocity information is supplied by a tachometer feedback generator working together with an integrated incremental encoder, so the drive receives both continuous speed feedback and position counts for regulated motion. The motor is supplied with no blocking brake, so any suspended or vertical load must be held by external means when power is removed.

The square frame is classified as motor size B, allowing direct coupling to gearboxes that use the same bolt circle. Encoder hardware attaches at the rear with a standard mounting pattern, which keeps the feedback assembly aligned without special adapters. This arrangement supports compact machine designs that rely on analog servo control and integrated position sensing. The rear-mounted feedback section also helps preserve a short front-to-back machine profile where adjacent axes or guarding leave little clearance.
