Why do air compressors adopt permanent magnet synchronous motors?
In industrial production, air compressors are considered “energy-consuming giants”, and the performance of their motors directly determines the operating costs, efficiency and reliability. The essence of equipping air compressors with permanent magnet synchronous motors is to solve th...Read more -

The influence of bearings on motor efficiency
What are the differences between 2RZ and 2RS bearings? Simply put, 2RS has rubber seals on both sides, while 2RZ has dust covers on both sides. One is contact type and the other is non-contact type. 2RS has less noise, but its precision is not very high and cannot reach P5 level. The basic dimens...Read more -
A high-voltage motor will generate corona discharge. Why does a variable-frequency motor do the same?
Corona discharge occurs when an uneven electric field is generated by a non-smooth conductor. Around the non-uniform electric field and near the electrode with a small radius of curvature, when the voltage rises to a certain level, due to the ionization of air, a discharge will occur, forming a c...Read more -
Analysis of the Causes of Motor Bearing Heating Issues
The bearing system is a very crucial quality and operational element of motor products. The overheating of bearings is often the main cause of bearing system failure. Overheating of bearings can lead to the degradation and failure of bearing grease, causing deformation of the inner and outer ring...Read more -
Why does the motor shaft turn blue?
For most readers, the term “bluing” is not unfamiliar. Bluing is a process where steel or steel parts are heated to an appropriate temperature in air, water vapor or chemical agents to form a blue or black oxide film on the surface. However, for motor components, it is often not due t...Read more -
What effects does a decrease in voltage have on the motor?
I. Current Variation According to Ohm’s Law, the relationship among current I, voltage U, and resistance R is I = U/R. In motors, resistance R (mainly stator resistance and rotor resistance) usually does not change much, so a decrease in voltage U will directly lead to an increase in curren...Read more -
The requirements and influences of special environmental conditions on motor insulation
The special environmental conditions of motors can be classified into two major categories based on the nature of the environmental factors: natural climate environments and industrial environments. Natural climate environments mainly include tropical, marine, cold, underground and plateau enviro...Read more -
What are the impacts of different winding insulation treatment processes on the quality of motors?
The insulation treatment of windings is an insulation reinforcement measure carried out under the condition that the insulation structure of the windings meets the design requirements. That is, through the impregnation and baking process, the insulating varnish penetrates into all the gaps of the...Read more -
Bearings suitable for high-temperature, low-temperature and polluted environments!
Bearings are one of the most crucial components of motor products. Special operating conditions impose extremely high demands on the bearings themselves and their lubrication. For instance, high-temperature environments, low-temperature environments, large temperature fluctuations, and environmen...Read more -
Why is the efficiency of permanent magnet motors higher?
The permanent magnet synchronous motor is mainly composed of stator, rotor and housing components. Similar to ordinary AC motors, the stator core is of laminated structure to reduce iron loss caused by eddy current and hysteresis effect during motor operation; the windings are usually of three-ph...Read more -
Permanent Magnet Synchronous Motor
Permanent magnet Synchronous motors, especially rare earth permanent magnet motors, are a refreshing presence in the field of motors. Compared with traditional electrically excited motors, permanent magnet motors not only have a simple structure and reliable operation, but also are small in size...Read more
