Product Description:

The MAC025C-0-QS-2-E/040-B-0 is an AC servo motor manufactured by Bosch Rexroth Indramat for use in compact motion systems. This rotary unit works with external analog drive amplifiers to provide closed-loop motion in assembly cells, pick-and-place heads, and other light-duty positioning applications used in industrial automation. Its compact format is useful where installation space is limited and moving mass must be kept low. That makes it a practical choice for smaller servo axes that need repeatable speed and position control during continuous machine cycles.

A no holding brake arrangement means the shaft is not mechanically locked when power is removed, so any suspended or backdriving load must be secured by drive torque or an external brake. Heat is removed by natural convection, which avoids the need for auxiliary blowers or liquid-cooling hardware. The frame size is C, which corresponds to the third width step in the MAC range and sets the mounting pitch and shaft height. Motor power and protective earth conductors are routed through a single connector on side B. This keeps the main current connection grouped on one end of the motor and can simplify cable routing in compact assemblies.

Velocity information returns to the drive through tacho feedback, because the built-in DC tachogenerator supplies a proportional voltage for responsive speed regulation. The magnetic stack follows length code 025, giving the motor a short axial dimension that suits confined mounting spaces while still supporting its intended torque range. As part of the MAC AC Servo Motors line, the unit uses the installation style associated with that product group. Its classification as a motor for analog drives shows that it is matched to controllers that use continuous current command signals rather than modern fieldbus-based communication. This operating method suits legacy motion systems that depend on analog amplifier control and direct speed feedback from the motor.
