Product Description:

The MAC112D-0-HD-2-C/130-A-0 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drive controllers, it converts electrical power into controlled torque and speed for indexing tables, gantry axes, and other automated machinery. It is suited for motion systems that require steady speed regulation and repeatable positioning during continuous operation. Integrated speed feedback supports stable response when the paired drive amplifier corrects for load changes across the motion cycle.

In continuous duty, the shaft reaches 1500 rpm, a speed that fits many analog amplifiers and keeps gearbox ratios modest. Heat leaves the housing through natural convection, so airflow around the fins must remain unobstructed, and the absence of fans removes extra wiring. Built-in tacho feedback supplies real-time velocity data to the regulator, helping the controller add damping during rapid reversals. A centering diameter of 130 mm aligns the flange to gearboxes or mounting plates without shims and helps prevent lateral movement during high-cycle operation. Electrical behavior follows winding code HD, which identifies the coil set used for this speed-torque class. Because the motor is supplied without a blocking brake, static load holding must be handled by external clamping or by maintaining drive current.

The tacho generator produces 3 V/1000 rpm, giving the controller a proportional signal for precise speed regulation. Power conductors are routed through a connector on side A, which supports cable runs along the machine frame and allows broader bend radii for thick leads. Frame size 112 combined with motor length D sets the installation depth and rotor inertia for this housing. The motor uses standard tacho quality for general motion tasks, and the cooling method does not require auxiliary fans or filters. This arrangement keeps the motor body simple and avoids external cooling hardware that would take additional space near the axis.
