Product Description:

The MAC025B-0-ZS-2-E/040-A-0/S001 is an AC servo motor produced by Bosch Rexroth Indramat and supplied as part of the MAC AC Servo Motors series. Designed for legacy servo amplifiers, it converts the command voltage from a controller into controlled shaft motion. In automated tooling, packaging lines, and material handling axes, the unit delivers precise angular position and speed so that coupled machinery can follow programmed profiles without mechanical overshoot. This operating style is useful on feed axes and small positioning tasks where smooth response and repeatable correction are important during frequent starts and stops.

Cooling relies on Natural convection to remove stator heat, so no external blower or liquid circuit is required and cabinet airflow must allow free circulation around the housing. Integrated tacho feedback produces an analog voltage proportional to rotor speed, allowing the controller to close the velocity loop without a digital encoder. The motor is supplied without a blocking brake, so any axis that must hold a load when power is off requires a mechanical clamp or static drive torque. This arrangement suits legacy servo amplifiers that depend on analog speed feedback and straightforward motor connections for stable operation.

The frame is classified as Size B, giving the motor a compact square flange that fits directly onto small gearboxes and linear stages. A stator stack length code of 025 sets the electromagnetic depth, balancing continuous torque against overall weight for portable or gantry-mounted assemblies. Power conductors reach the winding through a connector on side A, so cable trays should approach from that direction to avoid tight bends and crowded routing near the machine face. Because the motor is intended for analog drives, its voltage constants, inertia, and feedback style are matched to classic current-controlled amplifiers rather than modern fieldbus motion modules.
