What is the reason for the motor shaft to break?
When a motor shaft breaks, it means that the motor shaft or a part connected to the shaft breaks during operation. Motors are critical drivers in many industries and equipment, and shaft breakage can cause the equipment to stop running, resulting in production interruptions and losses. The follow...Read more -
What are the requirements for magnetic materials for different types of motors?
1 Requirements for magnetic materials of different types of motors Different types of motors have different requirements for magnetic steel due to their different use requirements and environments. The following is divided into three parts: focusing on the different requirements of...Read more -
Talking about the back electromotive force of permanent magnet synchronous motor
1. How is back electromotive force generated? Back electromotive force is also called induced electromotive force. Principle: the conductor cuts the magnetic lines of force. The rotor of the permanent magnet synchronous motor is a permanent magnet, and the stator is wound with coils. When the rot...Read more -
Why do these problems always occur on motor rotors?
In the failure cases of motor products, the stator part is mostly caused by the winding. The rotor part is more likely to be mechanical. For wound rotors, this also includes winding failures. Compared with wound rotor motors, cast aluminum rotors are much less likely to have problems, but once a ...Read more -
How to choose an electric sightseeing vehicle?
A few days ago, a user left a message: There are currently more than a dozen electric vehicles in the scenic area. After several years of frequent use, the battery life is getting worse and worse. I want to know how much it will cost to replace the battery. In response to this user’s messag...Read more -
6 ways to improve motor efficiency and reduce losses
Since the loss distribution of the motor varies with the power size and the number of poles, in order to reduce the loss, we should focus on taking measures for the main loss components of different powers and pole numbers. Some ways to reduce the loss are briefly described as follows: 1. Incre...Read more -
If a low-speed electric four-wheel vehicle encounters these 4 situations, it can no longer be repaired and needs to be replaced immediately
For low-speed electric four-wheel vehicles, they have a certain service life, and when their service life is exhausted, they need to be scrapped and replaced. So, in which specific situations can no longer be repaired and need to be replaced immediately? Let’s explain it in detail. There ar...Read more -
Four-wheel low-speed electric vehicles: Answers to controller-related questions
First, let’s take a brief look at the four-wheel low-speed electric vehicle controller: What it is used for: It is responsible for controlling the main high-voltage (60/72 volt) circuits of the entire vehicle, and is responsible for the three operating conditions of the vehicle: forward, re...Read more -
Why is the maximum range of low-speed electric vehicles only 150 kilometers? There are four reasons
Low-speed electric vehicles, in a broad sense, are all two-wheeled, three-wheeled, and four-wheeled electric vehicles with a speed of less than 70km/h. In a narrow sense, it refers to four-wheeled scooters for the elderly. The topic discussed in this article today is also centered around four-whe...Read more -
The consequences of misalignment of the motor stator and rotor cores
Motor users are more concerned about the application effects of motors, while motor manufacturers and repairers are more concerned about the entire process of motor production and repair. Only by handling every link well can the overall performance level of the motor be guaranteed to meet the req...Read more -
Solve the problems caused by the use of electric vehicles by replacing the electric vehicle batteries
Lead: The US National Renewable Energy Laboratory ( NREL ) reports that a gasoline car costs $0.30 per mile, while an electric vehicle with a range of 300 miles costs $0.47 per mile, as shown in the table below. This includes initial vehicle costs, gasoline costs, electricity costs and th...Read more
