Induction Heating Device
Working Principle
The system operates using electromagnetic induction technology.
When alternating current flows through the yoke, it creates a magnetic field. Once a metal workpiece is placed on the yoke, eddy currents are produced within the material itself. These internal currents generate heat from the inside out, allowing fast and even temperature increase without open flame or oil immersion.
This controlled heating process avoids local overheating and protects material structure.
Key Features
Uniform internal heating of bearings and gears
Temperature or time control modes available
No open flame or oil contamination
Automatic demagnetisation after heating
Air-cooled structure for workshop use
Suitable for maintenance and production environments
The non-contact heating method improves operational safety and helps maintain a clean working area.
Advantages Compared with Traditional Heating Methods
Compared to oil bath, gas flame or resistance heating:
Faster heating cycle
Lower overall energy consumption
No smoke, residue or carbon contamination
Reduced risk of material surface damage
More precise temperature management
This makes induction heating suitable for modern industrial assembly standards.
Application Scope
The induction heating device is widely used in:
Electric motor repair workshops
Pump and compressor servicing
Steel and cement plant maintenance
Gearbox assembly lines
Mining and heavy equipment maintenance
It is suitable for bearings, gears, couplings, bushings and similar circular metal parts.
