Product Description:

The MAC025C-0-QS-4-E/040-A-1/WI651LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. The unit converts electrical commands into controlled shaft motion for positioning tables, pick-and-place heads, and other industrial axes. Its compact housing is suitable for multi-axis machinery used in packaging, printing, and electronic assembly lines. A standardized mounting interface supports consistent alignment with compatible machine components and associated drive equipment.

The motor has a frame size of 025 and a frame length of C, providing a compact mechanical profile for machinery with limited installation space. Heat generated by the stator is removed through natural convection, eliminating the need for forced-air ducts or liquid cooling lines. This cooling method requires adequate open space around the housing so heat can dissipate into the surrounding air. A standard blocking brake keeps the shaft stationary whenever the drive is disabled, helping prevent load drift on vertical or offset axes. Power conductors reach the stator windings through a connector on side A, allowing cables to be routed alongside adjacent motors without obstructing the output shaft or mounting flange.

The control loop uses tachometer feedback to provide the drive amplifier with shaft-speed information during operation. Its primary position device is an incremental encoder with standard mounting, which supplies real-time shaft-position data for accurate motion regulation. The feedback arrangement allows the amplifier to correct deviations caused by changing loads, acceleration, or deceleration. The unit is configured as a motor for analog drives, so its signals are compatible with analog velocity and position control loops rather than fieldbus-based feedback interfaces. The shared MAC mounting geometry also supports consistent pilot alignment, shaft coupling, and cable placement when several coordinated axes are installed in the same machine.
