Product Description:

The MAC112D-1-ED-4-C/130-B-1/WI525LV is an AC servo motor produced by Bosch Rexroth Indramat in the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts drive-amplifier commands into controlled torque and speed for equipment such as gantries, packaging axes, and printing lines. It is intended for axes that rely on external servo amplifiers for closed-loop motion control. By combining tacho feedback with surface cooling, the unit supports consistent motion in industrial automation where cycle accuracy is important. This type of motor is commonly used where repeatable starts, stops, and speed changes are required across successive machine cycles.

A standard blocking brake is mounted at the rear of the shaft and can hold up to 45 Nm when the drive is disabled. During operation, the rotor reaches 3000 rpm, a speed suited to the velocity loops used in MAC drive packages. The stator windings use code ED, which indicates the electrical values used with medium-current amplifiers. Heat from copper losses is removed through axial surface cooling, and an auxiliary blower rated at 230 V AC moves air across the housing. The D-length stack adds active magnetic length without increasing the front mounting dimensions. The brake supports holding at standstill, while the blower helps manage motor temperature during extended operation.

With a centering diameter of 130 mm, the flange aligns precisely to mating machinery, and the frame size 112 keeps bolt patterns consistent across the MAC family. The centering shoulder also helps position the motor accurately against machine faces or adapter plates. Electrical power is introduced through a connector on side B, which helps with right-angle cable routing in compact panels. For velocity regulation, the tachogenerator delivers 3 V/1000 rpm, and the signal is intended for standard-quality speed control. Position feedback is supplied by an incremental encoder mounted in the standard configuration, so shaft position can be monitored without a separate external feedback device.
