Product Description:

The MAC025B-0-ZS-4-E/040-B-0/WI656LV/S007 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is intended for analog drive systems in industrial automation, where precise speed and torque regulation are required for axes such as pick-and-place gantries, conveyors, or packaging spindles. By converting controlled electrical input from an analog amplifier into rotary motion, the unit forms the electromechanical interface between the drive electronics and the mechanical load. This arrangement allows the connected drive to regulate acceleration and steady-state speed with repeatable response during machine operation.

The electromechanical form factor centers on motor size 025 with motor length B, a combination that sets the overall diameter, length, and continuous torque potential. Heat is removed exclusively through natural convection, so the installation must allow free airflow when ambient temperatures rise. Power is supplied through a plug-style connector on side B, which helps route cables along the back of a cabinet or robot arm. The motor is supplied without a blocking brake, so any vertical axis requires an external clamp or holding torque from the drive.

On the control side, the motor is classified as a motor for analog drives, meaning its winding constants match amplifiers that deliver proportional current rather than digital field-oriented control. For speed or position supervision, it can use tacho feedback, an incremental encoder, or an absolute encoder. In this version, the factory-mounted option is an incremental encoder with standard mounting, which provides uniformly spaced pulses for velocity loops and a reference track for homing. These feedback functions support accurate speed monitoring and repeatable axis positioning in legacy analog systems.
