Product Description:

The MAC090B-0-PD-2-C/110-L-0/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. It serves as a motor for analog drives, converting voltage-controlled commands from legacy amplifier stages into controlled shaft torque and speed for automated machinery. This unit suits material-handling axes, indexing tables, and general motion tasks that still rely on analog reference signals while requiring reliable dynamic response.

Winding code PD identifies the stator’s electrical layout, setting phase resistance and inductance so current rises predictably when paired with a matching drive. A centering diameter of 110 mm locates the flange accurately on the mounting surface and keeps the shaft concentric with downstream mechanics. Heat is removed by natural convection, eliminating the need for external blowers and allowing quiet operation inside cabinets with limited airflow. The motor develops its rated speed at 1500 rpm, which matches common gear ratios and supports steady operation in moderate-speed applications. For velocity feedback, the internal tacho generates 3 V/1000 rpm, giving the controller a linear voltage proportional to actual rotor speed for analog closed-loop regulation.

The motor has no blocking brake, so applications that require locked positioning must use an external brake or maintain drive excitation. Velocity information is returned through tachofeedback, allowing the amplifier to monitor rotor speed without relying on a digital encoder. Power conductors exit through a connector on the left side, which helps route cables toward the motor’s left flank and away from adjacent assemblies. The tacho is classified as standard, which indicates normal production calibration and linearity for this motor type. This arrangement supports stable analog speed regulation without adding separate feedback hardware.
