Product Description:

The MAC090B-2-PD-3HC/110-A-1/S001 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It functions as a motor for analog drives, providing controlled torque and velocity to machine axes, packaging stations, and transfer lines that depend on proportional command signals rather than fully digital buses. By converting drive current into rotary motion with precise speed feedback, the unit helps maintain repeatable operation in automated equipment such as printing presses and material-handling gantries. This arrangement makes the motor suitable for existing systems that still rely on analog command structures.

This model employs an external blower rated at AC 115 V, forcing air along the stator ribs to supplement its built-in axial surface cooling path. The added airflow helps remove heat from the housing during continuous operation and supports stable thermal performance at lower shaft speeds. Alignment with gearboxes or mounting bells is aided by a 110 mm centering diameter machined into the end shield, which helps minimize radial runout after installation. When powered through the drive, the rotor reaches a nominal speed of 1500 rpm without exceeding thermal limits for the PD winding group. Electrical energy is delivered through a sealed connector, and the designation connector on side A indicates that both power and ground conductors exit toward the drive cabinet to ease harness layout.

Velocity feedback is handled by an integrated tacho generator, and the ordering code specifies delivery with tacho feedback and a second shaft end so the sensor mounts opposite the load coupling. The second shaft end provides space for the feedback arrangement without interfering with the main drive connection. The generator produces 1.5 V/1000 rpm, giving the controller a linear voltage proportional to actual speed for analog regulation. Winding code PD indicates the resistance and inductance values used with legacy MAC drives for stable current control. A standard blocking brake engages automatically when supply power is removed, keeping the axis locked at standstill.
