Product Description:

The MAC112D-0-HD-4-C/130-A-1/WI520LX/S05 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Built as a motor for analog drives, it converts current-controlled commands into precise rotary motion for positioning axes in automated equipment. The design pairs a motor size 112 stator with a D-length housing to provide the inertia and thermal mass needed for mid-range load handling in packaging lines, transfer stations, and general machine tools. Its integrated feedback arrangement also supports closed-loop motion control in systems that use external analog amplifiers.

Mechanical installation is aided by a centering shoulder that measures 130 mm in diameter, which helps locate the flange accurately against the machine frame. A blocking brake is integrated and can hold the shaft with up to 45 Nm when power is removed, helping prevent back-driving on vertical axes. Heat is removed by natural convection, eliminating the need for an external blower. Under rated excitation, the rotor reaches 1500 rpm, matching line-synchronous speeds used in analog control loops. Three-phase power is delivered through a connector on side A, which can simplify cable routing when the drive cabinet sits to the left of the motor.

For velocity feedback, the unit includes tacho feedback with an incremental encoder; the built-in tachogenerator supplies 3 V/1000 rpm, allowing the controller to derive speed directly from the voltage signal. The encoder uses standard mounting, and the tacho accuracy is classified as Standard for general-purpose regulation. Winding code HD balances copper fill and resistance so continuous current can be sustained without forced cooling. This feedback arrangement allows the drive to monitor shaft speed and position without separate external transducers.
