Product Description:

The MAC025B-0-ZS-3-E/040-B-0/S001 is an AC servo motor produced by Bosch Rexroth Indramat and supplied as part of a compact motion platform for the MAC product line. It is intended for closed-loop motion axes where an analog velocity or torque command must be translated into repeatable rotary output. The motor forms the electromechanical link between a drive amplifier and the mechanical load in automated lines, conveying accurate speed regulation while maintaining compact installation dimensions. Its compact format also suits tightly spaced mechanisms where available mounting space is limited.

In the MAC AC Servo Motors series, this model relies on natural convection for thermal management, so heat moves through the housing surface without auxiliary blowers and reduces maintenance points. The motor has a size of 025 and a length of B, which set the stack height and active magnetic volume. Field cabling is routed through a keyed plug configured as a connector on side B, helping keep wiring orderly in compact cabinets. Because the housing dissipates heat directly, the allowable mounting orientation is unrestricted as long as free air can rise along the fins. This layout is useful where the rear of the machine offers limited space for additional cooling hardware.

The feedback package combines tacho feedback for velocity looping with a mechanically coupled second shaft end, allowing an external encoder or fan to be attached when additional monitoring or airflow is required. For holding duties during power-off, the unit contains no blocking brake, so position retention must be handled by the drive or by an external mechanical lock. Classified as a motor for analog drives, it accepts ±10 V or similar current references and delivers the corresponding torque profile without digital protocol overhead. This arrangement supports simple integration in systems that use analog command structures rather than network-based motion control.
