Difference between Medium and High Frequency Induction Heating Equipment

Different Frequencies 

Induction heating equipment with a frequency of 1-10Khz is usually regarded as medium-frequency induction heating equipment, and induction heating equipment with a frequency above 50Khz as high-frequency induction heating equipment.

Different Quenching Depth

Affected by the frequency of induction heating equipment, the quenching depth of the two is also different. The quenching depth of medium frequency induction heating equipment is generally 3.5-6mm, while that of high frequency induction heating equipment is 1.2-1.5mm.


Different Diathermy Diameters

Medium frequency induction heating equipment has great advantages in the diathermy of workpieces. It is mainly used for diathermic heat treatment of workpieces. It can perform diathermic heat treatment on workpieces with a diameter of 45-90mm. However, high-frequency induction heating equipment can only dilute the thin and small workpieces.


Induction Heating VS Other Heating Methods

Induction heating is different from some common heating methods in that it does not rely on convection and radiation to transfer heat to the surface of the product. Instead, the surface of the product generates heat through current, and then the heat from the surface of the product is transferred to the product through heat conduction. The depth of direct heating using induction current depends on the electrical reference depth.


Unlike some combustion methods, induction heating can be precisely controlled regardless of batch size. By changing the current, voltage and frequency of the induction coil, fine-tuned engineering heating can be achieved, which is very suitable for precision applications such as surface quenching, quenching and tempering, and annealing. The precise heating control provided by induction is unparalleled. In addition, using the same heating principle as the vacuum crucible heating application, induction heating can be carried out in the atmosphere for continuous application. For example, bright annealing of stainless steel tubes.

Induction Heating Machines FAQs


How does an induction heating machine work?


An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor.


What are the main parts of induction heating machine?


The stator of the three-phase induction motor consists of three main parts: Stator frame, stator core, and stator winding or field winding.


How is the speed of an induction motor determined?


In most cases, you can look inside the motor and count the number of poles in the winding; they are distinct bundles of wire evenly spaced around the stator core. The number of poles, combined with the ac line frequency (Hertz, Hz), are all that determine the no-load revolutions per minute (rpm) of the motor.


What is the difference between synchronous machine and induction heating machine?


The stator winding of the induction motor is energized from an AC source. While a synchronous motor always runs at a synchronous speed and the speed of the motor is independent of load, an induction motor always runs less than the synchronous speed.


Why starters are used in induction motor?


The three phase induction motors are self-starting due to rotating magnetic field. But the motors show a tendency to draw very high current at the time of starting. Hence there should be a device which can limit such high starting current. Such a device which limits high starting current is called a starter.
