Product Description:

The MAC025B-0-ZS-4-E/040-A-0/WI671LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. It is intended for closed-loop motion axes that rely on precise velocity and position regulation. As a motor for industrial automation, it couples to analogue drive amplifiers where it transforms commanded current into proportional torque for machine tooling, packaging, or assembly tasks.

This unit follows the frame designation of B and uses a stack length code of 025, establishing its mechanical envelope and continuous torque capability. Thermal dissipation occurs through natural convection, so no external blower or liquid circuit is required; installation must therefore allow free air circulation around the housing. Power conductors terminate through a connector on side A, which keeps the cable exit aligned with adjacent components for compact cabinet layouts. The rotor is held solely by drive torque because the motor ships without a blocking brake, making external braking or vertical load countermeasures necessary when static holding is demanded.

The feedback interface supports a tachofeedback incremental or absolute encoder option, enabling either speed-proportional voltage monitoring or digital position data exchange with the drive controller. The delivered sensing hardware is an incremental encoder with standard mounting, offering high-resolution shaft position signals through a multiturn-capable disc and corresponding receiver electronics. Electrical commutation and control loops are matched to analogue velocity controllers because the device is a motor for analogue drives. These characteristics align with integration guidelines from Bosch Rexroth Indramat, ensuring compatibility with their legacy MAC servo amplifiers while retaining the flexibility to interface with third-party motion systems that accept incremental encoder feedback.
