Product Description:

The MAC025C-0-QS-4-E/040-B-1/WI673LV/S007 is an AC servo motor supplied by Bosch Rexroth Indramat for positioning and velocity control tasks in analog drive systems. It belongs to the MAC AC Servo Motors series and translates armature current from a drive amplifier into proportional torque for machine axes, conveyors, or pick-and-place modules. Compact frame geometry and internal rotor construction make the motor suitable for installations where responsive motion is needed without added forced-air hardware. This operating profile fits equipment that relies on repeated starts, stops, and controlled speed changes during normal production.

This model is built on frame size C and stack length 025. Those values correspond to the laminated core height and active magnetic length, which influence continuous torque capacity and mounting dimensions. Heat generated by copper losses is dissipated through natural convection, so the motor does not require fans or liquid lines. The power leads exit through a keyed circular plug on connector on side B, which helps cable routing when the shaft faces the workpiece. Classified as a motor for analog drives, the unit works with voltage-command or current-command amplifiers rather than fieldbus-based controllers.

A standard blocking brake is integrated to hold the shaft when the drive is disabled, helping prevent load drift on vertical or overhung axes. Rotor position and velocity are monitored by tacho feedback with an incremental or absolute encoder, allowing the feedback arrangement to match the required control bandwidth. When incremental sensing is used, the motor is supplied with an incremental encoder with standard mounting, which supports compatibility across similarly configured MAC motors. This combination supports closed-loop operation in applications that require steady speed feedback and accurate position tracking during motion.
