Product Description:

The MAC025B-0-ZS-4-E/040-A-1/WI652LV is a compact AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for integration with analog drive controllers, it converts command voltages into precise rotary motion that keeps assembly stations, compact conveyors, and tooling axes on their programmed paths. By combining an integrated feedback device with a low-inertia rotor, the unit supports closed-loop positioning duties that require repeatable velocity and torque control in industrial automation.

The motor uses frame designation B and stator stack code 025. These dimensions suit a compact flange pattern, shaft height, and thermal mass for fractional-kilowatt output. Heat generated during operation leaves the housing through natural convection, so no external fan or liquid circuit is needed. The three-phase supply conductors terminate in a connector on side A, keeping power cables parallel to the machine bed and away from fastening hardware. Rotor position and speed are returned to the controller by tacho feedback with an incremental or absolute encoder, allowing either high-resolution pulses or absolute position data to suit the analog interface being used.

For load-holding situations, a standard blocking brake engages automatically when current is removed, helping prevent shaft movement in vertical or indexed applications. Additional position supervision is available through the dedicated incremental encoder with standard mounting, which bolts directly to the motor end shield to maintain alignment accuracy. Supplied as a motor for analog drives, the unit uses signal levels and pin assignments that match ±10 V motion cards common to legacy control platforms. This arrangement supports integration with existing analog control hardware without requiring a different drive concept.
