Product Description:

The MAC025A-0-WS-3-E/040-A-0/S007 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed as a motor for analog drives, it supplies closed-loop velocity and torque control to positioning tables, feeders, and similar automation axes. By combining permanent-magnet excitation with frame-integrated feedback, the unit delivers the fast response needed in industrial production lines. This operating style supports repeatable motion in packaging equipment, transfer mechanisms, and other systems that need stable low-speed behavior and quick correction of load changes.

The motor uses winding designation WS, which matches the electrical characteristics expected by legacy analog amplifiers. The motor size is 025, and the compact A length keeps the housing short while preserving useful torque density for light automation axes. Heat is removed by natural convection, so the housing releases losses to the surrounding air without external fans. For power cabling, a connector on side A places the phase connection at the drive end of the housing and helps simplify routing in confined machine spaces. The compact body also helps when the motor is mounted close to guards, slides, or adjacent hardware with limited clearance.

The motor has no blocking brake, so vertical or suspended loads must be held by external mechanics or by drive torque when power is removed. Rotor speed feedback is supplied by integrated tacho feedback on a second shaft end, allowing the amplifier to monitor motor speed during closed-loop operation. As a motor for analog drives, the unit is suited to voltage-controlled amplifiers that rely on continuous feedback rather than digital current regulation. The assembly is produced by Bosch Rexroth Indramat, and hardened bearings with precision balancing help support smooth running across the speed range. This arrangement is useful in applications that require steady rotation, repeatable acceleration, and direct compatibility with older servo control hardware.
