Product Description:

The MAC025B-0-ZS-4-E/040-B-0/WI670LV AC servo motor is produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for motion axes driven by analog amplifiers, it converts commanded current into controlled torque so actuators in pick-and-place cells, small gantries, or light machining centers can follow precise speed profiles. Integrated rotor feedback lets the drive close velocity and position loops, which supports repeatable motion during continuous operation. Its compact housing also helps the motor fit into installations where available space around the axis or inside the machine enclosure is limited.

This motor is supplied without a blocking brake, so load holding during power loss must be handled by external mechanics or the coupled drive. Thermal energy dissipates through natural convection, and the housing fins help keep winding temperature within the intended operating range without forced airflow. The stator stack follows length code 025, and the flange matches size B, which sets the mounting format and overall motor proportions. Power enters through a connector on side B, allowing cable routing to remain aligned with the axis in installations that need a clean side-entry layout.

The feedback circuit combines tacho feedback with an incremental or absolute encoder, giving the control loop both speed and position signals for stable regulation. For systems that only require incremental data, the standardized flange accepts an incremental encoder with standard mounting. Because it is classified as a motor for analog drives, the motor matches the signal and commutation requirements used by classic Indramat A and T amplifier families. This arrangement supports continued use in legacy automation equipment where analog control architecture remains in service and where stable low-speed behavior is still important for precise axis movement.
