Product Description:

The MAC115A-0-HS-2-F/130-B-1/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. Designed for analog drives, it converts commanded current into controlled torque and speed for positioning tables, presses, and packaging axes in automated plants. Integrated tachometer feedback allows the connected drive to monitor shaft velocity in real time, so closed-loop regulation remains precise even with load variations. Because the feedback device is built into the motor, the external drive can regulate speed without a separate sensing unit at the machine axis.

The integrated blocking brake delivers a holding torque of 45 Nm, so vertical loads remain stationary when the drive is disabled. A centering pilot of 130 mm aligns the flange with gearbox or machine frames, which helps reduce radial misalignment during installation. Heat generated during duty cycles is removed through natural convection, so no external fan or coolant is required. Velocity feedback is provided by a built-in tachogenerator, and the drive reads this tacho feedback signal for analog speed loops. Under rated conditions, the rotor reaches 2000 rpm, matching the speed class normally expected from MAC motors of this frame. Power conductors are routed through a connector on side B, allowing cable routing to remain clear of adjacent modules in tight cabinets.

The tacho produces 3 V/1000 rpm, giving the controller a predictable gradient for generating speed error signals. Its stator uses the HS winding code, which balances current demand and back EMF for dynamic applications that still rely on analog amplifiers. The motor is built in size 115, and length code A keeps the overall body compact enough for single-axis slides. The housing still leaves room for the standard blocking brake while maintaining a compact overall length.
