Product Description:

The MAC112D-0-ED-4-C/130-A-2/WI520-S018 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive systems, it converts command current into controlled rotation for positioning tables, gantries, and spindle axes. This type of motor is commonly used where smooth acceleration, repeatable stopping, and compact servo construction are needed in automated equipment. A size 112 frame in the D-length housing provides room for the tachogenerator and blocking brake, allowing the axis to remain secure when power is removed.

The brake supplies up to 60 Nm of static torque, securing the shaft against back-driving. A centering pilot of 130 mm aligns the flange with precision machine frames and helps limit radial misalignment during installation. Heat leaves the housing through natural convection, so the motor can operate without forced cooling when ambient airflow is sufficient. Under rated excitation, the rotor reaches 3000 rpm, which suits the speed range used in many analog servo applications. For feedback, the tachogenerator outputs 3 V/1000 rpm, giving the amplifier a speed signal that scales linearly with shaft rotation and supports stable closed-loop control as the load changes.

Power enters through a connector on side A, which keeps the cable run on the same face as many drive cabinets and can simplify routing in enclosed machines. Position information is provided by an incremental encoder with standard mounting, allowing the drive to monitor rotor angle during positioning tasks. The motor uses winding code ED, which corresponds to the electrical values assigned to this version of the series. Standard encoder mounting also matches the usual feedback arrangement for this motor platform, helping the amplifier receive consistent motion data during repetitive axis movement.
