Key to Improving Energy Efficiency in Compressor Motor Magnetization: How Does the ‘Internal Magnetization’ Process Work?
In industrial production, the compressor motor is the core equipment to maintain the operation of refrigeration, pneumatic system, but its long-term operation is prone to high temperature, vibration "demagnetization" problem - the internal magnetic steel of the motor magnetism is weakened, which not only leads to a surge in energy consumption, but also may cause the equipment This not only causes energy consumption to skyrocket, but also leads to equipment failures such as frequent starts and stops and increased noise. The reason why JUJI compressor motor magnetization technology can improve energy efficiency lies in its "internal magnetization" process, which precisely repairs the magnetic loss and returns the motor to a state of high-efficiency operation, and the logic of this process can be disassembled into three key links.
The first step is the "Magnetic Circuit Diagnosis", which is the basis for ensuring the effectiveness of magnetization. JUJI magnetizers use high-precision sensors to detect the distribution of magnetic circuits within the motor and locate areas of serious magnetic loss - for example, whether there is a localized magnetic degradation of the magnets in the motor rotor or an increase in reluctance due to wear and tear of impurities in the magnetic circuits. Unlike traditional "one-size-fits-all" magnetization methods, this diagnosis avoids magnet damage caused by blindly applying a magnetic field, and sets precise parameters for subsequent magnetization, just like a doctor determining a lesion through an inspection before formulating a treatment plan, ensuring the pertinence of magnetization from the source.
The core of the process is "precise magnetization reconstruction", which directly determines the effect of energy efficiency improvement. When the equipment determines the magnetic loss parameters, it will apply a directional magnetic field to the internal magnets of the motor through a special coil: the strength of the magnetic field will be dynamically adjusted according to the magnet material (e.g., neodymium-iron-boron, ferrite) and the original magnetic standard, so that neither too weak of a magnetic field will lead to incomplete magnetization, nor will it be too strong and cause the magnets to become "magnetically saturated". In this process, the "magnetic domains" (the basic units of magnetism) inside the motor, which were originally arranged haphazardly due to demagnetization, will be re-directed and arranged to form a regular magnetic circuit -- just like rearranging small magnets stacked in a haphazard manner into a neat queue, reducing the magnetic circuit's "reluctance" in the magnetic circuit. And when the magnetic resistance is reduced, less electrical energy is consumed to overcome the magnetic resistance when the motor is running, and the efficiency of converting electrical energy into mechanical energy is naturally increased, which is the core reason why the energy consumption of the motor drops after magnetization.
Finally, the "Magnetic Stability Reinforcement" phase guarantees the durability of the energy efficiency improvement. JUJI magnetization technology stabilizes the magnet steel after magnetization by means of a low-temperature cooling system to prevent the newly reconstructed magnetic domains from going out of order again due to temperature fluctuations. At the same time, the equipment will also carry out a second magnetic detection to confirm the uniformity of the distribution of the magnetic circuit, to ensure that the motor in the subsequent high-temperature, high-load operation, the magnetic decay rate slows down. This step is equivalent to "adding a layer of protective cover" to the magnetized magnets, so that the motor not only improves energy efficiency in the short term, but also maintains a stable magnetic level in the long term and reduces the maintenance cost of frequent magnetization.
In terms of practical application, JiuJu compressor motors that have undergone "internal magnetization" treatment can often increase energy efficiency by 10%-15%, while reducing the frequency of equipment failures. The value of this process is to accurately repair the magnetic loss, so that the motor returns to the high efficiency state of the design, rather than "extraordinary enhancement" - it does not rely on the replacement of core components, nor does it change the original structure of the motor, but from the essence of the magnetic to solve the problem of energy consumption, providing energy saving and cost reduction in the industrial sector. , which provides a more pragmatic technical path for energy saving and cost reduction in the industrial field.
