Rexroth MHD Series Motors
The Rexroth Indramat MHD motor is a brushless legacy servo motor still often found in service in printing, textiles, and packaging applications. The fully-sealed housing and lifetime lubricated bearings make this a maintenance-free motor. However, many of these have been in service since the 20th century. “Lifetime” bearings are designed for the expected lifetime of the motor. Since Rexroth produces the most reliable motion control systems on the planet, many of these motors are still in service long after the anticipated 10 years of life.
If your servo has been running beautifully for 20 years but the bearings were lubricated in the expectation of 10 years of service, it’s time for factory repair or reman — before something breaks.
Do you need Rexroth servo service?
If you’re already having trouble with your MHD motors, our experts can assist you. We can provide phone support for troubleshooting and help you make sure that you need repair or replacement. We provide field service when you need it. And we can get an emergency replacement unit to you fast, minimizing downtime at your facility.
They are available with a variety of configurations in motor feedback, holding brake, output shaft, and cooling method. These are the motor codes you’re most likely to see in service:
