Product Description:

The MAC090C-0-GD-4-C/110-B-1-IND belongs to the MAC AC Servo Motors series from Bosch Rexroth Indramat. It is a brushless AC servo motor intended to work with analog drive amplifiers, where it supplies precisely regulated torque and speed for automated tooling, material-handling axes, and general-purpose positioning tasks in industrial machinery. Because the motor is brushless, wear associated with mechanical commutation is reduced, which supports steady response over long production runs. The motor suits applications that require smooth acceleration and controlled deceleration during repeated motion cycles. Its feedback and brake features also help the axis remain responsive in operation and stable when motion is stopped.

The motor mounts to equipment frames through a centering flange that measures 110 mm in diameter, allowing repeatable alignment of the shaft relative to connected mechanics. Its stator uses winding code GD, which sets the electrical characteristics expected by compatible drive modules. Heat produced during cyclic duty dissipates by natural convection, so no auxiliary blower or liquid circuit is required. Cooling in this form also removes the need for separate fan wiring, which helps keep installation simpler in compact machine sections. Power conductors enter through a connector on side B, which helps keep cable routing clear of the machine's moving side A interface. The flange fit also helps reduce coupling misalignment, which supports smoother rotation and lower mechanical stress.

Position and velocity information are returned through a feedback package that supports tacho feedback, an incremental encoder, or an absolute encoder. This lets the connected control system use the level of feedback needed for either speed regulation or more exact position control. Holding torque during downtime is supplied by a standard blocking brake, letting vertical or indexing axes remain fixed when the amplifier is disabled. The brake can also help prevent unintended shaft movement when external forces act on the load after power is removed. Speed monitoring accuracy is maintained by its standard tacho quality, which keeps ripple within the limits expected by process control loops. The motor is classified as a motor for analog drives, so its electrical constants match legacy drive modules that rely on analog command voltages rather than fieldbus communication.
