China lifts restrictions, 4 foreign motor giants will build factories in China in 2023
Comprehensive lifting of restrictions on foreign investment in the manufacturing sector” was the blockbuster news announced by China at the opening ceremony of the third “One Belt, One Road” International Cooperation Summit Forum. What does it mean to completely lift restrictio...Read more -
Under the low-carbon orientation, which performance of the motor are the rigid requirements?
There are many series and categories of motor products. According to different performance tendency requirements, certain performance requirements of the motor will be stricter in specific occasions, such as strict requirements for motor torque, vibration noise and efficiency indicators. Starting...Read more -
Motor winding resistance analysis: How much is considered qualified?
What should the resistance of the stator winding of a three-phase asynchronous motor be considered normal depending on the capacity? (As for using a bridge and calculating the resistance based on the wire diameter, it is a bit unrealistic.) For motors below 10KW, the multimeter only measures a fe...Read more -
Why does the current increase after the motor winding is repaired?
Except for particularly small motors, most motor windings require dipping and drying processes to ensure the insulation performance of the motor windings and at the same time reduce damage to the windings when the motor is running through the curing effect of the windings. However, once an irrepa...Read more -
Effect of rotor shaft hole size on motor performance
In motor products, the shaft hole refers to the size of the rotor core and the shaft. Depending on the type of shaft, the size of the shaft hole is also different. When the shaft of the motor is a simple spindle, the size of the shaft hole of the rotor core is relatively small. , when the rotatin...Read more -
How to judge the inter-turn short circuit fault of motor stator winding
When a short circuit fault occurs between turns of the motor stator winding, it is generally judged by measuring the DC . However, the DC resistance of the stator winding of a motor with a large capacity is very small, and will be affected by the relationship between instrument accuracy and meas...Read more -
Causes of corona in high-voltage motor windings
1. Causes of corona Corona is generated because an uneven electric field is generated by an uneven conductor. When the voltage rises to a certain value near the electrode with a small curvature radius around the uneven electric field, a discharge will occur due to free air, forming a coron...Read more
