Product Description:

The MAC025B-0-ZS-3-E/040-A-1/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. In packaging lines, pick-and-place gantries, or tool changers, the unit converts electrical energy from a drive into tightly regulated rotary motion so a controller can position loads with repeatable accuracy. Its permanent-magnet rotor, closed-loop sensing, and compact frame allow the motor to be integrated into multi-axis assemblies where cycle time and footprint are critical production variables. The motor is suited to axes that require frequent starts, stops, and speed changes during repetitive machine cycles.

To keep vertical loads secure during power loss, the motor includes a standard blocking brake that clamps the shaft when excitation is removed. Heat produced by the windings is released through natural convection, eliminating the need for external blowers and simplifying enclosure design. Motor speed is reported through tacho feedback, which supplies an analog speed signal to the drive for continuous velocity regulation. That feedback allows the analog controller to correct speed deviations as load conditions change during motion. The stator frame is size B, indicating that the mounting face and bolt circle follow the smaller MAC envelope used in light-duty axes. It can be paired directly with legacy analog amplifiers without adapter cables or altered pinouts.

The mechanical options chosen for this model add a second shaft end, letting the machine use an auxiliary encoder, fan, or handwheel without interrupting primary power transmission. Stack length code 025 indicates a short magnetic core, which helps keep inertia and mass low for rapid acceleration profiles. Power conductors exit through a connector on side A, allowing cables to run parallel to the machine frame and stay clear of moving parts. Classified as a motor for analog drives, the device accepts sinusoidal current from proportional amplifiers and returns tachometer feedback to support smooth speed control across the operating range.
