Product Description:

The MAC025B-0-ZS-4-E/040-B-0/WI651LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it converts current-controlled commands from compatible servo amplifiers into precise shaft motion for positioning tasks in assembly lines, printing machines, and material-handling systems. The motor uses a permanent-magnet rotor and electronic feedback to maintain accurate speed and position during operation. Its compact stator package allows installation in confined machine spaces where a larger motor would interfere with nearby equipment or moving components.

The motor has a size of 025 and a motor length of B, providing a short axial envelope suitable for pick-and-place equipment and small rotary tables. Heat is removed through natural convection, so no additional blower or liquid cooling circuit is required. The mounting area must provide enough open space around the housing to support passive airflow and prevent excessive heat accumulation during continuous operation. Power conductors reach the winding through a keyed connector on side B, keeping the cable exit at the non-drive end for straightforward harness routing. Shaft position is monitored by an incremental encoder with a standard mounting interface, allowing the analog drive to process the returning quadrature signals for closed-loop motion control.

The motor has no blocking brake, so a vertical or overhung load must be secured by a mechanical lock or continuous motor torque when the axis is stationary. The feedback circuit includes tachofeedback lines, allowing the associated amplifier to receive real-time speed information in addition to position data. Provisions are available for an absolute encoder when single-turn reference retention is required with a compatible feedback option. External load-retention equipment should be selected according to the orientation and operating demands of the connected mechanism. Cable routing should also avoid sharp bends and moving machine parts so that the power and feedback connections remain secure during repeated motion cycles.
