MDS Series Mitsubishi Servo/Spindle Drives, Motors and Power Supply Units

Mitsubishi Electric released the MDS Series of Servo and Spindle parts during the early 90’s and at the time, these parts were the first AC digital drives with a common DC bus. The advantages these drives offered centered around power sharing and generating to achieve better efficiency during operation. While these servo and spindle units can be found throughout manufacturing plants world-wide, they were discontinued by Mitsubishi in 2004. ICR Services is the perfect partner to support and keep MDS series units working efficiently and operating according to the original OEM specifications.

ICR motor technicians begin the repair process for Mitsubishi motors with a thorough cleaning for both servo and spindle motors. If they are working on spindle motors, they’ll conduct a rewind on the motor. Servo motor repair differs a bit with technicians synchornizing the encoder of each motor. Both servo and spindle motors have all of their connectors replaced. The final step in the process for both types of motors involves a full rebuild. Our full rebuild to fix mechanical defects focuses on the bearings, seals, shafts, windings and other critical components.

the repair process for Mitsubishi drives and power supplies focuses on replacement of critical compoments. ICR electronic technicans remove and install new fans, capacitors, power components like transisters, rectifiers, and pre-drivers, communication IC’s and connectors. We’ve been repairing these electronic devices for so long, that our data-driven processes focus on refurbishing units, rather than just repairing issues.
