Three Phase Induction Motor Squirrel Cage is a common type of AC motor, powered by three-phase AC power supply, and is also known as Squirrel Cage Motor. It gets its name from the structure of the rotor, which consists of a number of metal guide bars, resembles like a squirrel cage in appearance. It is one of the most general used types of motors in industry.

Low noise operation: Using high-quality materials and precision machining technology, ensures the motor operates smoothly and with a low noise.
Widely used: Widely used in a variety of equipment that requires continuous operation and higher power, including fans, pumps, compressors, conveyor belts, machine tools etc.
harm of low cost motor
Three phase induction motor squirrel cages feature a simple structure and a low technical threshold. There are a large number of small and medium-sized motor manufacturers in the market, resulting in extremely fierce competition. Some manufacturers adopt a low-price competition strategy to attract customers in the short term. To achieve this, they reduce the motor's configuration, leading to substandard motor performance.
The following are the main cases:
1. Electromagnetic wire:
①Use thinner copper wire.
②Use aluminum wire or copper-clad aluminum wire instead of copper wire. This will cause the motor to have increased resistance during operation, generate more heat, and reduce the motor's performance and efficiency. Under high loads, it may even cause the motor to burn easily.
2. Iron core materials:
①Select low-quality silicon steel sheets or replace them with steel sheets. These have poor permeability and high iron loss. During operation, the motor will produce more eddy current loss and hysteresis loss, resulting in low motor efficiency and significant heat generation.
②Reduce the thickness of the iron core's laminated sheets. This will affect the motor's magnetic circuit performance and reduce the output power and torque of the motor.
3. Bearings:
Employ low-priced, inferior bearings. These bearings have low precision and a short lifespan, and are prone to wear, overheating, and noise issues, which affect the stability and reliability of the three-phase induction motor squirrel cage's operation.
4. Manufacturing process:
①Simplify the winding process, for example, reducing the number of turns of the winding or decreasing the tightness of the winding. This will impact the magnetic field distribution and electromagnetic properties of the motor, reducing its output power and efficiency.
②Not strictly control the assembly precision of the motor, such as having an uneven gap between the rotor and stator or an unsecure bearing installation. This will affect the motor's operation stability and noise level, and reduce its performance and lifespan.
Our Quality assurance
Our three phase induction motor squirrel cage are crafted from genuine materials and strictly adhere to national standards to ensure top-notch motor quality.
1. Utilize silicon steel sheets from Baosteel. Rigorously ensure the precise weight of the silicon steel sheets. This is highly beneficial for the heat dissipation of the motor, thereby prolonging its service life.
2. Employ 100% copper enameled wire to guarantee that the windings are tightly wound. This can prevent overheating damage to the windings and reduce the operating vibration of the motor windings, ensuring the stability of motor operation.
3. #45 steel rotating shaft. This ensures that the shaft will not deform when subjected to forces, enhancing the motor's overload resistance capability.
4. Precision-polished cast iron casing. Not only does this make the motor aesthetically pleasing, but it also assists in dissipating heat from the motor.
5. Conduct rotor dynamic balance tests and motor performance tests, etc. before leaving the factory. This ensures that the performance indicators of the manufactured motors meet the design requirements, providing customers with high-quality and reliable products.
