Product Description:

The MAC093B-0-OS-2-C/130-A-1/S005 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for analog drive controllers where rapid torque generation and speed feedback are needed to position machine elements with consistent accuracy. By combining a permanent-magnet rotor with an integral tacho generator, the unit supplies the drive amplifier with a proportional velocity signal so closed-loop regulation can be performed without external sensors.

The motor’s pilot diameter measures 130 mm, which provides the centering reference that aligns the flange with the driven load. Heat is removed by natural convection, so no external blower or liquid circuit is required when the housing is installed in free-air zones. For straightforward wiring, the three-phase supply is routed through a connector on side A, which helps reduce cable bends in axial mountings. The motor reaches a rated speed of 2000 rpm, and within this range the electromagnetic design maintains constant torque and a linear tacho output for predictable speed loops. A built-in tacho feedback element produces the voltage signal used by the controller, eliminating the need for a separate encoder in applications where only velocity information is necessary.

The motor uses a blocking brake to hold the shaft when power is removed and prevent drift on vertical axes. Its overall length follows the B length code, which provides additional stack height for higher continuous torque than shorter versions in the same motor family. The unit has a frame designation of size 093, identifying the stator diameter class used for this model. The tacho generator delivers 3 V/1000 rpm, giving the drive a straightforward scaling factor for speed control routines. The OS winding code indicates the resistance and inductance pairings expected by compatible analog amplifiers.
