Product Description:

The MAC112D-0-HD-2-C/180-A-0/S003 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog velocity and current controllers, the unit translates command signals into controlled torque and speed for gantry axes, transfer lines, and packaging machines. By pairing a rotor-mounted tachogenerator with a low-inertia stator, the motor maintains steady velocity while reacting quickly to load changes. Its standardized flange dimensions also support installation in established machine layouts where stable speed regulation and repeatable motion are required over long production cycles.

In mechanical terms, the motor is built on frame size 112, and its centering flange measures 180 mm, allowing precise alignment with gearboxes or machine frames. The rotor is rated for a nominal speed of 1500 rpm, giving a consistent velocity reference for legacy analog loops. Cooling relies on natural convection, so heat is shed through surface airflow rather than forced fans or liquid jackets. Integrated tacho feedback delivers a proportional signal of 3 V/1000 rpm, enabling the controller to monitor actual speed within a narrow error band. The tachogenerator is of standard quality, so its linearity and ripple are suited to normal production tolerances for medium-precision motion tasks.

The motor uses housing length D, which provides a deeper stator stack and supports higher continuous torque without changing the mounting pattern. Electrical power enters through a connector on side A, which can simplify cable routing when rear access is limited. The motor is supplied without a blocking brake, so static holding force must be furnished by the drive or by an external clamp on vertical axes. The HD winding uses resistance and inductance values suited to intermittent overload while remaining compatible with the motor's cooling method.
