Product Description:

The MAC025C-0-QS-4-E/040-B-1/WI673LV/S001 is an AC servo motor engineered by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for closed-loop motion axes, it converts analog velocity or torque commands into precise shaft rotation in packaging machines, pick-and-place units, and small assembly stations. Its compact frame and standardized mechanical interface allow direct coupling to compatible amplifier modules for repeatable speed control and accurate position holding. This layout is well suited to installations where a small motor must provide stable response during indexing, short travel moves, and frequent changes in commanded speed.

Thermal management for this model is handled through natural convection, so the housing dissipates heat to the surrounding air without fans or liquid jackets. Within the MAC family, it carries the frame designation size C and the stack length code 025, which correspond to a compact body with moderate thermal mass for this motor class. Electrical power reaches the windings through a connector on side B, which can simplify cable routing in tight machine spaces. Because it is classified as a motor for analog drives, its winding parameters and feedback scaling match controllers that use proportional current and velocity reference signals.

Axis holding during power-off conditions is provided by the standard blocking brake, which clamps the shaft when control voltage is lost. For motion feedback, the motor uses a dual-channel arrangement. A built-in speed generator supplies coarse speed data, and tacho feedback is supplemented by either an incremental encoder with standard mounting or an absolute encoder for single-turn position capture. This arrangement gives the drive immediate rotor information for speed regulation and position supervision without external transducers. It also helps the servo maintain stable stiffness during acceleration ramps and changing load conditions.
