Product Description:

The MAC090B-0-PD-3-C/110-B-1/S005 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is designed to drive mechanical axes in positioning and speed-controlled industrial automation systems where analog velocity commands are used. The motor converts electrical energy from the drive into controlled rotary motion for conveyors, tooling spindles, handling modules, and other axis functions that require steady response. This makes it suitable for equipment that relies on stable analog control loops rather than newer network-based motion platforms.

At its nominal speed of 1500 rpm, the shaft delivers rated torque while staying within thermal limits through natural convection cooling, so no external blower or liquid circuit is required. The motor uses a PD winding that matches the impedance and current ratings expected by legacy MAC drives. A centering boss diameter of 110 mm aligns the flange with gearboxes or mounting plates, which helps maintain accurate fit during installation. Power is routed through a single-turn plug-in connector on side B, allowing cable entry opposite the feedback housing. Because cooling is passive, the surrounding machine layout does not need extra airflow hardware for the motor itself.

Mechanical holding is provided by a standard blocking brake that engages when power is removed, helping prevent load back-drive on vertical axes. For velocity feedback, the motor includes tacho feedback on the rear shaft, and the permanent-magnet tachogenerator produces 3 V/1000 rpm for compatibility with analog control cards used in the MAC system. The rear arrangement also includes a second shaft end for optional encoders or manual override, which adds flexibility for applications that need additional feedback or manual positioning access. The unit is a motor for analog drives, so it works with controllers that process continuous voltage signals rather than digital fieldbus commands.
