Product Description:

The MAC025B-0-ZS-2-E/040-B-0/S007 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for use with analog drive amplifiers, the unit converts electrical command signals into controlled rotary motion for positioning and velocity tasks in industrial automation cells, material handling axes, and machine tool heads. The motor forms the electromechanical link between the drive electronics and the mechanical load. Its feedback and power connections are arranged for conventional analog motion systems that rely on direct wiring rather than networked control.

The motor relies on natural convection cooling, so heat dissipates through the housing without forced airflow. Rotor position and speed are reported through integrated tacho feedback, which supplies an analog voltage proportional to shaft velocity so legacy drive cards can close the speed loop directly. The mechanical stack uses motor length 025, indicating a short active core that helps keep inertia low for rapid response. Power conductors exit through a connector on side B, allowing cable routing along the non-drive end of the machine frame. Because the design includes no blocking brake, holding torque must be provided externally when the axis is de-energized.

The electromagnetic package corresponds to motor size B, which provides moderate continuous torque in a compact frame. As a motor for analog drives, it is electrically tuned to amplifiers that regulate armature current from analog command signals rather than fieldbus control. This arrangement suits existing equipment that uses analog speed loops and discrete control wiring. The unit remains part of the MAC AC Servo Motors line from Bosch Rexroth Indramat, where compatibility with established amplifier platforms is important.
