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
