Product Description:

The MAC112D-0-HD-1-B/130-A-1/J625/S005 is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive systems, it converts voltage and current commands into precise mechanical motion so automated stations can index parts, follow speed profiles, or hold position under load. Its construction and feedback arrangement make it suitable for closed-loop tasks where repeatable torque and velocity are indispensable in an industrial production cell.

This model is equipped with a blocking brake that can hold up to 45 Nm of static torque, allowing vertical or suspended axes to remain stationary when power is removed. Accurate mechanical alignment to adjoining machinery is achieved through a centering diameter of 130 mm. Heat is removed by natural convection, eliminating the need for forced air or liquid cooling hardware. Rotor position is monitored through incremental encoder feedback, which transmits sinusoidal or square-wave signals to the analog controller for real-time error correction. The motor uses the D length code, giving it a longer active stack than shorter variants and a higher continuous torque capability for the same frame size.

The frame is classified as size 112, indicating a stator outer diameter that matches other MAC units in this mechanical envelope. Under rated excitation, it reaches 1500 min⁻¹, a base speed that pairs with gear ratios or direct drives requiring moderate shaft speed. For velocity feedback to auxiliary electronics, the tacho generator produces 3 V/1000 min⁻¹, giving analog speed information without software scaling. Electrical energy is introduced through a connector on side A, and the electromagnetic design follows winding code HD, which identifies the resistance and inductance values used by compatible analog amplifiers.
