Product Description:

The MAC112C-0-KD-4-C-130-B-1-WI634LX-S005 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It serves as the drive element in analog control loops, translating command voltages from a controller into repeatable shaft movement for positioning tables, feeders, and similar automation axes. Its construction, accessories, and feedback options are intended for installations that must maintain consistent accuracy while operating from legacy analog amplifiers commonly found on existing production lines.

A blocking brake provides a mechanical holding function and can resist up to 45 Nm of static load, allowing vertical axes to remain fixed when power is removed. The motor centers on a flange with a 130 mm locating diameter, which simplifies rigid alignment to gearboxes or machine frames. Heat produced by the windings is released through natural convection; because no fan is fitted, mounting orientation and free airflow are important for continuous duty. Rated speed is 1500 rpm, a value matched to gear ratio selections that favor high torque over very high velocity. Power conductors exit through a connector on side B, which lets the cable bend away from the driven load and reduces strain on the gland plate. Torque is transferred through a shaft machined with a DIN 6885 keyway, providing positive engagement with standard keyed couplings.

The built-in tachogenerator outputs 3 V/1000 rpm, supplying speed feedback for analog drives that regulate velocity with an external amplifier. Winding code KD sets the phase resistance and inductance so the controller can deliver rated current without saturation. Size code 112 identifies the stator frame diameter and matches the motor to the corresponding mechanical options in the series. Length identifier C, standard tacho quality, and an incremental encoder with standard mounting complete the feedback arrangement, allowing the motor to provide both speed feedback and position feedback through its installed devices.
