Product Description:

The MAC093A-0-WS-2-F/110-A-0 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. In an analog drive system, it interprets voltage or current reference signals from a drive amplifier and converts them into controlled torque for synchronized machine motion. Its electromagnetic design supports rapid acceleration and deceleration, which suits packaging stations, indexing tables, and material-handling axes. It is intended for speed-controlled and positioning duties where stable response to changing loads is important. The motor also fits legacy control cabinets that still rely on analog setpoints, allowing those systems to keep their existing control approach.

The motor uses a centering diameter of 110 mm for accurate alignment with pilot recesses on gearboxes or mounting plates. Heat from the stator is removed by natural convection, so no auxiliary blower or liquid circuit is required when surrounding airflow is clear. This cooling method keeps installation simple because it does not require added fan wiring or coolant connections. Under rated excitation, the rotor reaches 2000 rpm, which suits mid-range servo loops while keeping bearing loads within normal operating limits. Electrical power is connected through a connector on side A, allowing the cable to exit parallel to the motor frame for compact routing inside a machine enclosure. For velocity feedback, the integrated tacho generator produces 3 V/1000 rpm, giving the amplifier a proportional signal for stable closed-loop regulation.

The winding code WS indicates the electrical characteristics matched to compatible analog amplifiers. The tachogenerator is set for improved smooth-running quality, which helps reduce feedback ripple and supports steady low-speed operation. The motor size of 093 with the short length A helps it fit installations where axial space is limited. This shorter housing can be useful in compact machine frames where couplings, guards, or adjacent components leave little rear clearance. The motor has no blocking brake, so vertical or suspended axes need an external holding device or maintained servo torque during power loss.
