Product Description:

The MAC090B-0-PD-4-C-110-B-1-WI517LV is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for coordinated motion in industrial automation, it supplies controlled torque and speed to axes driven by analog amplifiers. This allows machinery to follow command signals precisely during indexing, positioning, or velocity-regulated processes in production equipment.

The motor uses a centering diameter of 110 mm, which aligns the flange accurately with gearboxes or mounting plates. Heat generated by the stator windings is removed through natural convection, eliminating the need for an external fan and simplifying cabinet layouts. Under rated excitation the rotor reaches 1500 rpm, a speed that matches common line frequencies and reducer ratios in medium-duty applications. Power is supplied through a connector on side B, which keeps high-current conductors away from feedback cabling on the opposite face. The electromagnetic circuit uses a PD winding code, which corresponds to the voltage constant and current draw used by the associated analog drive module. A built-in tacho generator outputs 3 V/1000 rpm, providing a linear voltage reference that the drive electronics use for closed-loop speed regulation.

The feedback chain includes a tacho-feedback incremental or absolute encoder for position sensing. Holding capability during power-off conditions is delivered by a standard blocking brake, preventing shaft rotation on vertical or static loads until drive torque is restored. This unit is classified as a motor for analog drives, so it is used with amplifier cards that process continuous reference voltages instead of fieldbus commands. Tacho quality is standard, and the incremental encoder is mounted in the conventional position to streamline alignment during installation.
