Product Description:

The MAC090A-0-RD-2-C/110-A-0 is an AC servo motor built by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. It converts electrical drive commands into precise rotary motion for positioning tables, packaging axes, and handling modules. In industrial automation, the motor supports closed-loop speed and torque control while remaining compact enough for direct coupling to gear stages or load shafts. This type of motor is commonly used where repeatable acceleration and deceleration are needed for synchronized machine movements. Its servo design allows the connected amplifier to adjust current continuously so the shaft follows commanded motion with low lag.

The mechanical interface uses a centering diameter of 110 mm, allowing the motor to seat directly in standard machine flanges without additional pilot rings. Cooling is provided by natural convection, so heat is dissipated through the housing surface and the installation should allow free airflow around the frame. Because cooling is passive, the surrounding machine area should not trap heat against adjacent surfaces or covers. The motor is supplied with no blocking brake, which means holding force must be provided by drive torque or an external locking device when power is removed. Power conductors connect through a connector on side A, and the unit is classified as a motor for analog drives for use with amplifiers that respond to analog speed or torque references.

For closed-loop regulation, the feedback system uses integrated tacho feedback rather than a digital encoder. Its standard tacho quality provides a speed-related voltage that is suitable for general-purpose motion control and stable response over the normal operating range. The signal can be read directly by compatible analog velocity controllers, allowing the amplifier to correct speed changes as the mechanical load varies. Because the feedback remains analog, the motor fits control systems that were built around tacho evaluation instead of serial encoder protocols. This makes the unit suitable for maintaining existing motion platforms that use conventional analog servo loops.
