Yes. In many cases, a failed servo motor can be repaired, refurbished or fully overhauled rather than replaced.

A servo motor repair can include inspection and fault diagnosis, bearing replacement, encoder inspection or replacement, winding repairs, insulation testing, cleaning, mechanical repairs and electrical testing.

The correct approach depends on the motor, its condition and the reason for failure. At Fletcher Moorland, we assess each servo motor individually to establish whether repair is viable and identify the underlying cause of failure.

The cost of repairing a servo motor depends on the manufacturer, model, fault, condition of the motor and parts required.

A motor requiring bearings and routine servicing will obviously cost less to repair than one requiring rewinding, encoder replacement or extensive mechanical work.

Rather than automatically recommending replacement, a proper assessment can establish whether the existing motor can be economically repaired. This can be particularly valuable when dealing with expensive, obsolete or difficult-to-source servo motors.

Repair times vary depending on the motor, fault and availability of specialist components.

For critical production equipment, the priority is to establish the fault quickly and provide a clear assessment of the work required. Some repairs can be completed relatively quickly, while more complex overhauls may require additional machining, rewinding, encoder work or specialist components.

Fletcher Moorland operates 24/7, supporting customers with critical motor repairs and component requirements when downtime cannot wait until the next working day.

Servo motors can fail for a number of reasons, including:

• Bearing wear or failure
• Encoder faults
• Winding or insulation failure
• Excessive heat
• Contamination from oil, coolant, dust or moisture
• Mechanical damage
• Overloading
• Poor alignment
• Excessive vibration
• Electrical faults
• Age and general wear

Importantly, repairing the immediate fault doesn't always address the reason the motor failed. Identifying the root cause can help prevent the same failure from happening again.

Yes. Specialist repair can be particularly valuable when a servo motor is obsolete, discontinued or no longer supported by the original manufacturer.

Replacing an obsolete servo motor isn't always straightforward. The replacement may require modifications to the machine, changes to controls or programming, or may simply be unavailable.

Repairing and extending the life of the existing motor can therefore be a much more practical option.

Fletcher Moorland supports customers with the repair and refurbishment of obsolete and difficult-to-source servo and specialist motors, helping keep existing machinery operational for longer.

As a specialist servo motor repair workshop we’re able to work across a wide range of manufacturers rather than being restricted to one OEM.

Fletcher Moorland repairs servo and specialist motors from a broad range of manufacturers, including Siemens, ABB, Fanuc, Yaskawa, Mitsubishi, Bosch Rexroth, Indramat, Lenze and others.

The important consideration isn't simply the manufacturer's name. The repairer needs the specialist knowledge, test equipment and experience required to correctly diagnose and test the particular motor.

If you're unsure whether a particular servo motor can be repaired, providing the manufacturer, model and fault details is a good starting point.

Yes. Encoder problems are a common consideration when diagnosing servo motor faults.

Depending on the motor and encoder, repair work may involve inspection, testing, replacement or specialist encoder related work.

Because the encoder provides feedback to the drive or control system, an encoder problem can result in issues such as positioning errors, loss of synchronisation, or intermittent operation.

Proper testing is therefore an important part of establishing whether the encoder is responsible for the fault or whether the underlying problem lies elsewhere in the motor or control system.

A repaired servo motor should be thoroughly tested before being returned to service.

The exact tests depend on the motor and repair, but can include electrical tests, insulation resistance, winding resistance, surge testing, mechanical inspection, encoder checks and functional testing.

At Fletcher Moorland, specialist test equipment is used throughout the repair process to help establish the condition of the motor and verify the repair. This includes testing on OEM drives like Siemens, SEW, Indramat, Schneider etc where possible.

The aim isn't simply to make the motor run again. It's to give the customer confidence that the motor has been properly inspected, repaired and tested before it returns to production.

Often, yes; although it depends on the fault and the condition of the motor.

Repairing an existing servo motor can avoid the cost of a new replacement, while also reducing the potential downtime and engineering work associated with changing to a different motor.

This can be particularly important for obsolete, specialist or high-value servo motors, where replacement units may be expensive or difficult to source.

A professional assessment can establish whether repair represents the most economical option before committing to a replacement.

Yes. Fletcher Moorland operates 24/7, providing support for critical motor repairs and component requirements.

When a servo motor failure stops production, waiting until the next working day isn't always an option. Rapid diagnosis and access to specialist repair capability can make a significant difference to the overall cost of a breakdown.

Our servo and specialist motor repair capability covers diagnosis, overhaul, testing and repair across a wide range of industrial applications and manufacturers.
