Product Description:

The MAC025B-0-ZS-3-E/040-B-1/S001 is a compact AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is intended for position and velocity control on assembly machines, pick-and-place axes, and light tooling spindles. The unit converts analog drive commands into precise mechanical rotation. As an electromechanical actuator, it generates continuous torque in step with drive current, allowing machine elements to be regulated directly without belts or gear stages, and its mounting pattern fits many standard industrial frames. That direct response helps light axes follow commanded speed changes with minimal mechanical complexity.

The motor uses natural convection for passive cooling, so heat is removed without external air movers and cabinet airflow planning remains simple. A standard blocking brake is included, and it clamps the rotor when power is removed to hold vertical loads until the drive is energized again. The motor has a frame size of 025 and a frame length of B, which keeps inertia moderate for agile acceleration. Power is connected on side B, allowing the harness to exit opposite the driven shaft and helping limit cable bend at the entry point. This layout supports clean cable routing where space around the axis is limited.

Speed feedback is provided by integrated tacho feedback, and a dedicated second shaft end allows an encoder or manual handwheel to be added without changing the primary output coupling. The extra shaft end is useful when an auxiliary feedback device or a handwheel must share the motor without altering the main shaft connection. With this arrangement, position verification can coexist with the analog tachometer signal required by legacy controllers. Classified as a motor for analog drives, the device supports precise motion in systems that continue to use established amplifier technology.
