Product Description:

Bosch Rexroth Indramat manufactures the MAC093A-0-PS-3-C/110-B-1 as part of the MAC AC Servo Motors series. This servo motor is intended for analog drive systems, where precise torque and speed regulation are needed for positioning, conveying, or machining tasks in industrial automation. By supplying torque directly to a coupled load, it reduces mechanical transmission slack and helps maintain tight process tolerances.

The motor body seats on a flange with a centering diameter of 110 mm, which keeps the stator concentric with the driven assembly and limits vibration. Heat is removed through natural convection, so no external blower or liquid loop is required. A nominal speed of 3000 rpm matches common 50 Hz and 60 Hz drive electronics, giving predictable velocity profiles across global installations. The PS winding code matches the coil impedance and thermal limits to the rated current of compatible analog amplifiers. For field wiring, power is connected through a connector on side B, allowing the cable to exit toward the drive panel and reducing bend strain in vertical mounting positions. Motor length is the compact A variant, which shortens the stack without changing the 093 frame profile. The motor is intended for analog drives where sinusoidal commutation is handled externally.

A standard blocking brake holds the shaft during power loss, preventing back-driving on vertical axes and aiding fixture changes. The frame is classified as motor size 093, which indicates the stator diameter and interface dimensions. Speed feedback is produced by a tacho generator that outputs 3 V/1000 rpm, and this analog voltage feeds directly into legacy regulators for closed-loop control. The feedback package includes tacho feedback and a second shaft end, so an additional encoder, fan, or mechanical sensor can be coupled without disassembling the primary drive. Tacho quality is standard and provides ripple characteristics suitable for most positioning loops.
