Product Description:

The MAC025A-0-WS-4-E/040-B-0/WI673LV/S001 is a compact AC servo motor produced by Bosch Rexroth Indramat in the MAC AC Servo Motors series. Designed for analog drives, it converts electrical command signals into controlled rotary motion for positioning and velocity tasks in automated machinery. The integrated feedback system supplies real-time shaft data to the drive controller, enabling closed-loop regulation of actuators, pick-and-place heads, and light-duty conveyors. This continuous exchange of motion data allows the controller to correct deviations caused by changing loads or commanded speed transitions.

Thermal management relies on natural convection, so heat dissipates through the housing without active fans. The surrounding installation must allow sufficient airflow across the motor surface to prevent heat from accumulating during operation. The electromagnetic circuit uses winding code WS, which corresponds to the electrical characteristics required by a compatible drive. The motor has a size of 025 and a compact A length, providing a short housing and low rotor inertia for responsive movements. The stator leads exit through a connector on side B, allowing power cables to be routed away from equipment mounted near the opposite side of the housing.

The motor has no blocking brake, so the drive or an external mechanism must hold the load when stationary positioning is required. This configuration avoids the additional rotating mass associated with an integrated brake, which supports rapid acceleration in light-duty motion axes. Feedback is provided through tacho feedback with an incremental or absolute encoder, supporting both speed-regulated and position-regulated control loops. The installed sensor is an incremental encoder with standard mounting, making it suitable for systems that use pulse-based position information. Its standard mounting arrangement provides a consistent mechanical interface for alignment with the motor shaft. The encoder signals give the connected drive the position and velocity information needed to regulate movement throughout each operating cycle.
