Product Description:

The MAC025A-0-WS-4-E/040-B-0/WI670LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is intended for use with analog drives where precise speed and torque regulation are required in automated machinery such as indexing tables, pick-and-place axes, and small gantry stages. The motor converts the drive's armature current into controlled mechanical motion by synchronizing its electromagnetic field with command signals from the associated amplifier. Its compact format suits motion tasks that require repeatable starts, stops, and speed changes without a large mounting footprint.

The electromagnetic assembly uses the WS winding code, which indicates the stator winding arrangement used for this motor. Frame proportions follow size 025, and the active magnetic stack uses length A, giving the unit a compact form factor for tight machine frames. Heat generated during operation is removed through natural convection, so no external blower or liquid circuit is required. This cooling method keeps the motor mechanically simple and avoids separate airflow hardware around the axis. Power conductors are routed through a connector on side B, allowing cable egress toward the rear of a cabinet when the motor is flange mounted.

Speed feedback is handled by tachofeedback, while the command loop relies on a standard-mounted incremental encoder for high-resolution position tracking. The motor is delivered without a blocking brake, so any load-holding requirement must be addressed by the drive or an external mechanical lock. Closed-loop accuracy is improved by dual-channel feedback, and both encoder and tachometer signals are routed in a shared connection to keep wiring orderly. The feedback combination helps the paired drive respond quickly to load changes during low-speed operation and short indexing moves. This arrangement lets the motor work with legacy analog amplifiers that expect separate speed and position channels while still supporting retrofit control systems.
