Repairing Indramat MDD Servo Motors

Reman Indramat MDD Servo Motor

Indramat MDD AC servo motors are known for their precision, power, and reliability—everything you could ever want in an industrial servo motor. While these motors can handle everything, they may need service, repair, or replacement over time. Here’s what you need to know about repairing Indramat MDD servo motors.

Make sure that the motor is defective

Indramat faults and error codes don’t necessarily indicate problem with your motor. Interference, a bad cable, pollution, or inadequate cooling can cause your servos to stop working. If this is the case, replacing your MDD servo won’t solve the problem; it just wastes money.

What do you do if your MDD motor stops working?

You can replace your MDD servo. However, you can’t just swap out your old Indramat MDD servo with any other MDD motor. There are several different types of MDD motor.

  • MDD-021, MDD-025, and MDD-041 motors are low profile with a high power density. These motors were popular for screwing applications, auxiliary axes and tool changing devices.
  • MDD-065, MDD-071, MDD-093, and MDD-115 have high power density and were built for dynamic applications. This includes tool changing devices, and roller feeds for pressing, punching, and nibbling machines.
  • MDD-090 and MDD-112 servo motors are intended for high-precision applications, such as grinding machines.

You must match your type codes exactly to prevent downtime and additional repair costs. This is one of the biggest risks of buying a replacement Indramat motors from a third party.

Even if you do get the correct replacement servo, there’s no guarantee that the unit is in good condition or that it was stored properly. Indramat motors haven’t been made in 20 years—that’s plenty of time for that motor to be misused or damaged.

Repair is often your best bet.

Indramat products, including servo motors, are not designed to be repaired in situ. You can’t disassemble and reassemble your industrial servo motor in the field. The only way to get a reliable repair is by sending your unit in for an Indramat factory repair. Factory repair guarantees that your unit is correctly and efficiently.
