Product Description:

The MAC025C-0-JS-2KE/040-B-1/S008 is a compact servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. As a rotary actuator for automated machinery, it converts commanded current from analog servo drives into controlled torque and speed, allowing precise positioning of machine axes and material-handling equipment. The unit fits installations that need moderate continuous power and a limited footprint, such as turret heads, small pick-and-place gantries, or auxiliary axes on packaging lines. Its compact form also helps when the motor must be placed close to guards, tooling, or transfer mechanisms where surrounding space is restricted.

Thermal management relies on natural convection, so the stator housing dissipates heat directly to ambient air without forced airflow or liquid jackets. A standard blocking brake is integrated; when the control voltage is removed, this spring-applied device holds the shaft stationary to secure vertical loads or maintain tooling alignment. Winding code JS identifies the coil resistance and torque constant used with legacy MAC analog amplifiers. Mechanical length index 025 indicates the shortest stack in the MAC025 subfamily, which helps reduce inertia and supports rapid acceleration in light-duty servo loops. This cooling approach also avoids the added noise and extra wiring associated with separate fan-assisted systems.

Additional integration details include size C, which uses a mounting flange pattern common to other medium-frame Rexroth motors. Rotor position is reported through tacho feedback, providing a velocity-proportional signal that legacy analog controllers use for speed loops. Power conductors exit through a connector on side B, which can simplify cable routing when the motor is flange-mounted with the B-end facing the panel. Its classification as a motor for analog drives supports compatibility with ±10 V command stages and amplifiers used across the MAC AC Servo Motors platform. This arrangement is useful in retrofit systems that continue to rely on established analog control architecture rather than newer digital feedback interfaces.
