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 -
