Product Description:

The MAC025B-0-ZS-2-E/040-B-1/S001 belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It is a rotary drive element intended for motion loops that require accurate velocity and position regulation in analog control architectures used on packaging stations, pick-and-place axes, and light material-handling gantries. In these systems, the motor converts commanded electrical input into controlled shaft motion for repeatable axis travel and stable speed control. It can be used in machines where closed-loop analog control remains part of the installed platform and a compact motor package is preferred. When paired with a matching power stage, it provides a compact source of cyclic torque that supports precise interpolation without external gear reduction.

The motor uses a series-standard resolver feedback arrangement and supplements it with integrated tacho feedback, so analog drives can derive instantaneous speed directly from a DC signal. This combination gives the controller both rotor position information and a direct speed reference during continuous motion. Cooling is handled by natural convection, with heat transferred from the stator housing to the surrounding air without fans or liquid circuits. This cooling method keeps the motor layout simple because no separate airflow hardware is required around the housing. A factory-installed blocking brake holds the load when the drive is disabled, which helps prevent back-driving on vertical axes or during emergency stops.

Power leads exit through a side B connector, allowing the motor to sit close to nearby machine surfaces without forcing a tight bend in the conductors. This arrangement can make cable routing easier in compact machine layouts where clearance around the motor body is limited. The rotor-stator stack uses length 025, and the frame follows the size B profile, which gives a balance of inertia and torque for rapid indexing where space is limited. The unit is intended as a motor for analog drives rather than digital fieldbus systems. It works with controllers that modulate current and voltage by analog command levels, and this operating style fits legacy CNC and process equipment that requires consistent electrical characteristics during daily use.
