Product Description:

The MAC090B-0-PD-3-C/110-B-1 AC servo motor belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. As a motor for analog drives, it pairs with voltage-controlled amplifiers to provide closed-loop speed and position regulation in automated machinery. By converting electrical reference signals into repeatable rotary motion, the unit supports packaging stations, metal-cutting feed axes, and other tasks that require consistent acceleration profiles while integrating mechanical and sensing features suited to mid-frame installations.

The electrical profile uses winding code PD, which indicates the phase resistance and inductance so current limits in the associated analog amplifier match the motor’s thermal capacity. At rated excitation, the rotor reaches 1500 rpm, a nominal speed chosen for applications that balance moderate torque with fine velocity resolution. Heat generated in continuous service is removed by natural convection, eliminating the need for external blowers or liquid circuits. Accurate mechanical alignment is aided by a 110 mm centering diameter that positions the flange concentrically against gearboxes or machine plates. Power conductors enter through a connector on side B, allowing cable routing away from moving parts or adjacent axes.

To maintain position when the drive is disabled, the motor includes a blocking brake as a standard feature for this frame size. Speed feedback uses tacho feedback and a second shaft end, allowing an external encoder or handwheel to be coupled without adapters. The tachogenerator produces 3 V/1000 rpm, providing a linear voltage reference for analog controllers that correct slip or load disturbances. Signal stability is supported by standard tacho quality, which limits ripple and phase error so velocity loops can achieve tight regulation without additional filtering.
