Product Description:

The MAC025B-0-ZS-2-E/040-B-1 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It converts commanded current into controlled torque for positioning, speed-controlled, or tension-regulated axes within industrial automation. Permanent-magnet excitation is paired with a compact rotor, enabling responsive acceleration for medium-duty machine tools, pick-and-place modules, and packaging stations. Its streamlined housing allows installation in tight machine frames and retrofit projects that require precise motion without adding significant mass.

A standard blocking brake is fitted so the shaft can hold position when the drive is powered down, minimizing mechanical drift on vertical or high-inertia loads. Heat produced during continuous duty is removed by natural convection, so no additional fan or liquid circuit is required; this simplifies mounting in sealed cabinets. Velocity information reaches the controller through integral tachofeedback, which delivers a proportional voltage signal for closed-loop speed regulation. The electromagnetic stack corresponds to motor length 025, delivering the rated torque envelope within a short body. Frame proportions follow motor size B, which defines the flange pattern and shaft geometry used across the MAC family.

Installation details complete the electrical interface. The stator winding is energized through a connector on side B, letting cables exit away from adjoining axes to avoid interference. Because it is engineered as a motor for analog drives, command loops rely on proportional amplifiers rather than field-bus networks, keeping the unit compatible with legacy machine panels. The field performance record of Bosch Rexroth Indramat supports integration in long-life production lines, while adherence to the MAC AC Servo Motors series dimensional code ensures spare-part interchange without re-tooling.
