Product Description:

The MAC025A-0-WS-4-E/040-B-0/WI652LV is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for closed-loop positioning and velocity control, this motor converts electrical commands from drive amplifiers into precise mechanical rotation for industrial automation axes such as pick-and-place heads, index tables, or feed rolls. Its electromechanical architecture aligns with the manufacturer’s motor for analog drives platform, making it suitable for legacy motion systems that require stable speed regulation and repeatable position correction during continuous operation.

Cooling is handled by natural convection, allowing the housing to shed heat without blowers or external liquid circuits. This approach keeps the motor mechanically simple while limiting continuous current to what the housing can dissipate on its own. The stator’s electrical profile uses winding code WS, which identifies the rated voltage, resistance, and inductance expected by the paired controller. A compact frame with motor size 025 and length code A gives the unit a short overall body that fits in tight machine envelopes, while power conductors exit through a connector on side B to keep cabling away from the load side.

For feedback, the motor uses an incremental encoder with standard mounting, which supplies phase-shifted pulse signals for position and speed monitoring. The broader feedback arrangement is listed as with tachofeedback and an incremental or absolute encoder, indicating compatibility with legacy control schemes that use analog command stages rather than digital fieldbus links. The motor has no holding brake, so applications that require static load retention must rely on external clamping or drive-generated torque. This arrangement suits machine axes where stopping force is handled elsewhere and where compact motor packaging is more important than an integrated brake assembly.
