Description
1. Product Description
The INDRAMAT MAC 90A-0-RD-2-C/110-A-0 is an AC servo motor from the Bosch Rexroth Indramat MAC series, designed for industrial motion control applications. It converts electrical energy into controlled rotary motion and is suitable for machine tools, automated production equipment, material handling systems, and other machinery requiring regulated speed and positioning.
This model belongs to the MAC 090 frame family and features an RD winding configuration, tachometer feedback, and a 110 mm centering diameter. The motor is designed for use with a compatible servo amplifier in a closed-loop control system. Its precise operating characteristics depend on the winding, feedback arrangement, cooling configuration, and drive electronics.
For replacement applications, confirm the complete nameplate code, motor connector orientation, shaft and flange dimensions, feedback signals, and amplifier compatibility. Do not substitute a similar MAC 090 variant without checking its electrical and mechanical specifications.
