Product Description:

The MAC112D-1-ED-1-B/130-A-0/J1250 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is intended for analog drive systems that need precise velocity and position control on automated machine axes. In operation, the motor converts commanded electrical input into controlled rotary motion so the drive can regulate acceleration, running speed, and stopping behavior with repeatable response. Its winding and overall motor length support continuous torque and speed regulation for tasks such as tool handling, conveyor positioning, and cutting head movement in industrial automation cells.

A centering pilot of 130 mm seats the motor on the machine frame, helping maintain radial alignment and consistent shaft concentricity during installation. Heat removal relies on axial surface cooling, in which external airflow moves along the housing fins to keep the stator within its thermal range during sustained operation. That airflow is supported by a dedicated AC 230 V blower supply, separating the cooling circuit from the drive’s main power connection. At a nominal speed of 3000 rpm, the motor supports fast indexing and reversing, while the D motor length provides a longer active section that increases continuous torque without changing the mounting interface.

Frame size code 112 establishes the shaft height and flange pattern used throughout the MAC family, allowing use with compatible couplings or gear units. Position data is returned through incremental encoder feedback, so the controller counts pulses for closed-loop regulation and tracks shaft movement throughout the commanded travel. Power conductors exit on side A, which can reduce cable loops inside narrow enclosures and simplify routing near the motor face. An integrated tachogenerator delivers 3 V/1000 rpm, allowing legacy analog velocity loops to operate without external sensors. The motor is supplied without a blocking brake, so static holding torque must be provided by the machine mechanics or by drive current alone.
