Product Description:

The MAC115A-0-HS-2-C/180-A-0 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for analog drives, the unit translates ±10 V command signals into proportional torque so that legacy motion controllers can operate feed axes, tool changers, or transfer stations without digital bus hardware. It is intended for closed-loop motion tasks where an external analog amplifier regulates motor current and speed from continuous command signals. Its mechanical interface follows the MAC frame pattern, which helps the motor fit established machine layouts in this product line.

The motor is supplied without a blocking brake, so static holding force must be provided by the drive or an external clamp. A centering pilot of 180 mm aligns the stator housing with the machine's locating bore to maintain concentricity. Heat is removed by natural convection, eliminating the need for fans or liquid circuits and simplifying cabinet ventilation. Rated speed is 2000 rpm, giving a predictable velocity range when paired with analog amplifiers that scale current linearly. The tachogenerator produces 3 V/1000 rpm, and this feedback voltage feeds the drive's speed loop so deviations are corrected in real time.

The stator uses the HS winding code, which indicates the copper fill and impedance used for this frame size. This winding selection sets the electrical behavior expected by compatible drive amplifiers during continuous servo operation. Overall dimensions correspond to motor size 115, and length category A keeps mass low for axes with limited counterbalance while preserving the frame geometry of the platform. Power leads exit through a connector on side A, permitting straightforward cable routing when nearby components leave limited space around the motor. Rotor speed information is derived from internal tacho feedback, and its signal quality is classed as standard for mid-bandwidth positioning tasks.
