- 2024-09-24What is the difference between IC81W and IC86W in AC MOTOR?
Motor cooling method is a very tangled issue in high-voltage motor ordering, involving multiple factors such as cost, installation space, and ventilation and heat dissipation effects. Today, let's talk about the commonly used cooling methods ...
- 2024-09-23The harm and inspection of pinholes on enameled wire
Enameled wire is the most widely used electromagnetic wire in the production of low-voltage products. A key performance requirement of this electromagnetic wire is the continuity of the paint film, that is, to check the number of pinholes in ...
- 2024-09-20Does simulation technology affect motor performance?
Motor products involve multiple physical elements such as electricity, magnetism, wind and heat. They are seemingly simple but actually complex products. The performance of motors depends on the complex coupling relationship between electro ...
- 2024-09-19What are the basic characteristics of high-efficiency motors
As the country's requirements for product energy saving continue to increase, it is a challenge for any motor manufacturer. One is the challenge from motor technology, and the other is the challenge from manufacturing costs. However, most mo ...
- 2024-09-18Why is differential protection used on large high-voltage mo
Compared with small and medium-sized motors, high-voltage motors are expensive and are used in critical and special applications. Whether it is the disposal of the motor body after a failure or other problems ...
- 2024-09-14What is the impact of heat dissipation medium on temperature
Temperature rise is a very critical performance indicator of motor products. When the temperature rise of the motor is high, on the one hand, it will affect the surrounding environment, and on the other hand, it is directly related to its ef ...
- 2024-09-13Key points of quality control in high-voltage motor manufact
The motor is a relatively simple machine. When the stator and rotor are put together and the two end covers are buckled, it is a complete motor. However, such a simple machine integrates electromechanical energy conversion and the essence of ...
- 2024-09-12Factors causing overheating and burning of motor windings
1. Motor winding short circuit When one phase of the motor winding is short circuited, or one of the parallel branches is short circuited, it will cause the three-phase current to be unbalanced, causing the motor to overheat. ...
- 2024-09-11Rotor problems in permanent magnet motor applications
Different motor products have different advantages and applicability. Due to different working conditions, the requirements for motor product parts are also different. For example, for heavy-load working conditions, there are special require ...
- 2024-09-10Motor shaft voltage test method
The purpose of measuring the motor shaft voltage is to understand the magnitude of the motor shaft current. When the motor shaft current reaches a certain level, it will cause the motor bearing to overheat, the bearing or bearing seat to hav ...
