Can spray painting solve the problem of short circuit between turns of motor windings?
Inter-turn short circuit is an electrical fault that may occur during the production, processing and application of any motor winding. When an inter-turn short circuit fault occurs, can it be repaired and what measures should be taken? The winding and embedding of motor windings may have adverse ...Read more -
The performance of the bearing cage is different depending on the position of the bearing cage.
The cage is an important component of the bearing. Its function is to guide and separate the rolling elements, reduce bearing friction, optimize and balance the rolling element load, and improve the lubrication effect of the bearing. Observing from the appearance of the bearing, it is not necessa...Read more -
Why do variable frequency motors have cage rotor structures?
The wound rotor motor has a resistor connected in series to the rotor, so that the motor has a sufficiently large starting torque and a very small starting current (the multiple of the starting current is approximately equal to the multiple of the starting torque), and can also achieve a small-ra...Read more -
Can adding engine oil solve the problem of bearing noise?
Bearing noise and high temperature are problems that occur from time to time during the manufacturing and application of motors. In order to solve such problems, improving the structure of the bearing system and selecting appropriate lubricants are common methods and measures. In comparison, grea...Read more -
The motor is overloaded. Are the windings partially faulty or completely burned out?
Overload is a typical problem of motor products. It may be caused by a mechanical system failure of the motor body or insufficient motor capacity. It may also be an overload problem caused by the user during the operation of the motor. When an overload problem occurs in a motor, the windings will...Read more -
These rated parameters respectively represent different capabilities of the motor.
In the nameplate of the motor product, several important parameters such as the rated power, rated voltage, rated current and rated frequency of the motor will be stipulated. Among the several rated parameters, they are the basic parameters based on the rated power as the basic framework; for pow...Read more -
How to configure a more reasonable configuration for motors using angular contact ball bearings?
For vertical motors where axial force exists objectively, most angular contact ball bearings are used, that is, the axial load-bearing capacity of the bearing body is used to balance the downward axial force generated by the weight of the rotor of the vertical motor. In the structural design of t...Read more -
The relationship between the no-load current of motors with the same power but different pole numbers
No-load current refers to the size of the current when the motor is not pulling a load. In order to describe the size of the no-load current, the ratio of the no-load current to the rated current is often used for comparative analysis. To this end, we start with the relationship between rated cur...Read more -
The permanent magnet synchronous motor market will enter a stable period of development
With the introduction of the national double carbon target requirements and policies, high-efficiency motors have quietly become a necessary power source to support the large-scale equipment update process. In addition to traditional markets such as new energy vehicles and household appliances, h...Read more -
Effect of winding insulation paint on motor efficiency
Insulation treatment is a key factor in the reliability of motor products. In any motor manufacturing company, the insulation treatment process of windings is a key point of quality control. The quality of the insulating paint itself and the process control effect all affect the motor to varying ...Read more -
What links can easily lead to motor shaft breakage and quality problems?
Shaft breakage is a quality problem that occurs from time to time in motor products, and more often occurs in large-sized motors. The fault is characterized by the regularity of the fracture locations, that is, the root of the shaft extension, the root of the bearing position, and the weld end of...Read more -
Is it more cost-effective to replace the motor with a new one or remanufacture it?
Remanufacturing is a new measure currently proposed for the elimination of high energy-consuming equipment. Motor remanufacturing has once become a popular business for many motor manufacturers and repair units, and some units have specifically carried out motor remanufacturing work. With the gov...Read more
