Induction Motor is an important power source to drive all kinds of mechanical equipment. The improvement of its performance and efficiency is directly related to the energy saving, emission reduction and sustainable development of the whole industrial chain. As the Core component of Induction Motor, the quality and performance of Induction Motor Core are paid more attention to.

Good magnetic conductivity:

Induction motor cores are usually made of silicon steel sheets and other magnetic conductive materials, which have high permeability and can conduct magnetic field efficiently. This enables the rotating magnetic field generated by the stator winding to pass smoothly through the iron core and interact with the rotor, thus realizing the conversion of electrical energy to mechanical energy. High magnetic conductivity is helpful to improve the electromagnetic conversion efficiency of the motor, so that the motor can output more mechanical energy with the same electrical energy input.

Lower Energy Loss:

Low Iron Loss: iron core material selection and lamination process can effectively reduce the iron loss. The iron loss mainly includes hysteresis loss and eddy current loss. The high quality silicon steel sheet has good hysteresis property, narrow hysteresis loop and low hysteresis loss, meanwhile, the insulation coating between laminations can reduce eddy current generation and eddy current loss. For example, the use of special silicon steel sheet materials and advanced lamination technology, iron core loss can be controlled at a lower level, improve the overall efficiency of the motor.

Small mechanical loss: induction motor core structure design and manufacturing process to make the machine run more smoothly, reduce the friction, vibration and other factors caused by mechanical loss. For example, the size of iron core precision and installation accuracy, can ensure that the air gap between the rotor and stator is uniform, reduce the air gap caused by non-uniform mechanical friction and vibration, reduce mechanical loss.

High reliability and durability:

Simple and strong structure: induction motor core structure is relatively simple, no complex components and vulnerable parts. The Iron Core made of laminate has high mechanical strength and can bear electromagnetic force and centrifugal force during the operation of the motor, and is not easy to be deformed and damaged. This kind of simple and firm structure makes the induction motor can keep stable operation even in bad working environment, and has high reliability.

Good Heat Resistance: in the motor operation process, iron core will produce a certain amount of heat, but high-quality iron core material can withstand higher temperature, not overheat phenomenon. For example, silicon steel sheet at high temperature can still maintain good magnetic conductivity and mechanical strength, to ensure the normal operation of the motor. At the same time, good heat dissipation design is also helpful to reduce the core temperature and improve the reliability and service life of the motor.

Easy to manufacture and maintain:

Manufacturing process maturity: induction motor core manufacturing process is relatively mature, including silicon steel sheet stamping, lamination, welding and other processes. These processes have been long-term development and optimization, to ensure the manufacturing accuracy and quality of iron core. Moreover, in large-scale production, the manufacturing efficiency is high and the cost is relatively low.

Easy Maintenance: due to the induction motor core structure is simple, when the motor failure, easy to iron core inspection and maintenance. For example, if the iron core insulation coating damage caused by failure, only to repair the damaged parts or replace part of the laminate can be, low maintenance costs, maintenance time is short.

Adapt to a variety of working conditions:

Wide Speed Range: induction motor can change the power frequency, voltage and other parameters to achieve speed regulation, and in a wide speed range can maintain better performance. The good magnetic conductivity and low loss characteristics of iron core provide guarantee for motor speed regulation, which can meet the needs of motor speed under different working conditions.

Adapt to different loads: whether light or Heavy Load, induction motor core can be better adapted. In the light load, the motor efficiency is high, can save energy; in the heavy load, iron core can bear a larger electromagnetic force, to ensure the output power and torque motor, with strong overload capacity.

At present, the induction motor core has been widely used in industrial manufacturing, transportation, energy and other fields. In industrial manufacturing, it provides reliable power for all kinds of mechanical equipment; in the field of transportation, it promotes the development of green travel modes such as electric vehicles and rail transit; in the field of energy, improve the efficiency of power generation and transmission equipment.
