Motor Rotor Removal with Induction Heating | Case Study

Project Background

 

Motor repair work often needs rotor removal.
This job is not easy. If the method is wrong, it can damage the shaft or increase repair time.

 

A motor service company contacted us.
They needed a safe and fast way to remove a tight rotor without damage.

Customer Problem

 

Before using our solution, the customer had these problems:

Flame heating made the temperature uneven and hard to control

Pulling tools did not work well

The work took many hours

There was a risk of shaft damage

These problems slowed down their work and increased cost.

Our Solution

 

We provided an induction heating solution for rotor removal.

The machine heats the rotor in a controlled way.
The metal expands, so the rotor can be removed easily.

 

Main points:

 

  • Heating is even
  • Temperature is controlled
  • No contact with the part
  • Work is faster and safer

 

On-site Process

 

The solution was used at the customer site:

  • The coil was placed around the rotor
  • Heating started slowly
  • The rotor temperature increased step by step
  • The rotor was removed after expansion

 

The process was simple and safe.

 

Result

 

After using our solution:

  • Disassembly time was reduced by more than 70%
  • No damage to the shaft or rotor
  • Work became faster
  • Safety improved

 

Why Use Induction Heating

 

Induction heating is a good method for rotor removal:

  • Heating is even and controlled
  • No flame, no damage risk
  • Stable and repeatable result
  • Can be used for different rotor sizes
