Industrial Motor Repair for Plants, Machinery and Legacy Equipment
Defective motors can quickly cause unplanned downtime, production losses and costly follow-on damage in manufacturing plants. Whether the problem affects an electric motor, servo motor, AC motor or DC motor, fast industrial motor repair helps restore production.
We at retrofit GmbH provide manufacturer-independent motor repair, electrical fault diagnostics, overhaul and component replacement for industrial drives. We focus on legacy machinery and production-critical equipment, evaluating each motor together with its frequency converter, power electronics and higher-level control systems.
Maximum performance, minimum downtime
Industrial Motor Repair as an Economical Alternative to Buying New
When an industrial motor fails, the entire production line frequently comes to a halt. This is especially problematic if the motor is part of a legacy plant or if OEMs exhibit long lead times. Having a defective motor repaired preserves your maintenance budget and ensures rapid resumption of operations.
To find out which criteria determine whether an motor can still be overhauled, read the specialist article comparing repair, general overhaul, and replacement.
Our Service Promise
- 12 Months Warranty: Full warranty on all performed overhaul work and replaced components.
- Manufacturer-Independent Evaluation: Expert service for drives from all leading manufacturers.
- Short Downtime: Fast processing to prevent extended production interruptions.
When Overhauling Industrial Motors Makes Sense
- When a replacement motor in industry would incur high mechanical adaptation or re-tooling costs.
- In cases of bearing damage, winding shorts, housing defects, or encoder faults.
- When flange dimensions, shaft, or housing must match the existing machine mechanics exactly.
Fast exchange, maximum security
Technical Fault Analysis & Overhaul of Servo Drives
Thorough electrical and mechanical fault analysis forms the basis of every successful overhaul. During the overhaul of servo drives and AC motors, we inspect both the mechanical assemblies and the integrated feedback and brake systems.
Winding & insulation testing
Continuity and insulation testing for early detection of winding shorts and ground faults.
Bearing Inspection & Replacement of Motor Bearings
Mechanical runout testing and professional replacement of worn roller bearings and shaft seals.
Encoder & Feedback Service
Alignment, testing, and parameterization of resolvers, incremental encoders, and absolute encoders.
Is the motor controlled by a frequency converter or servo drive, and is there a fault? Take advantage of our professional frequency converter repair service.
Industrial Motor Overhaul for Custom Flanges, Windings and Encoders
Traditional Understanding of Motor Overhaul
Industrial motor overhaul is particularly economical when custom mounting flanges, specific windings or integrated encoders must be retained. Buying a standard replacement motor can require time-consuming modifications to the existing machine.
The Quality Promise of retrofit GmbH
We offer a transparent, manufacturer-independent diagnosis of your drive. We evaluate objectively whether winding re-working, bearing replacement, or a suitable replacement unit is most sensible.
Has a motor suffered catastrophic damage and become uneconomical to repair? Through our industrial motor procurement service, we can help source tested replacement motors and drive units.

Frequently Asked Questions (FAQ) About Industrial Motor Repair
When is industrial electric motor repair worthwhile?
Industrial electric motor repair is particularly worthwhile for custom mounting flanges, high-value servo motors and discontinued designs where replacement would require expensive machine modifications.
Can complex servo motors be repaired?
Yes. We repair servomotors including re-winding, bearing replacement, feedback encoder alignment (resolvers/encoders), and brake renewal.
How do I send a motor for repair?
First, send us the motor nameplate, manufacturer, power rating and fault description. We will then provide suitable shipping instructions. Secure the motor firmly to an appropriate pallet before transport.
Do you also check interaction with the variable frequency drive?
Yes. Because motors are frequently driven by variable frequency drives, we evaluate the electrical environment. If the drive is defective, we offer variable frequency drive repair.
What happens if the motor has irreversible winding or housing damage?
If the motor is beyond economical repair, we assist you through our industrial motor procurement service in sourcing identical replacement motors worldwide.
Is your electric motor defective, is the servomotor causing unusual noises, or is a drive axis standing still? Avoid long downtime and have your industrial motor repaired quickly, safely, and manufacturer-independently by the experts at retrofit GmbH!
