How to calculate the slip of an asynchronous motor?
The most direct feature of asynchronous motors is that there is a difference between the actual speed of the motor and the speed of the magnetic field, that is, there is a slip; compared with other performance parameters of the motor, the slip of the motor is the easiest to obtain, and any motor ...Read more -
Is there a difference in the speed of the asynchronous motor in different states?
Slip is a specific performance parameter of an asynchronous motor. The current and electromotive force of the rotor part of the asynchronous motor are generated due to the induction with the stator, so the asynchronous motor is also called an induction motor. To evaluate the speed of an asynchron...Read more -
How to measure the basic parameters of the motor?
When we get a motor in our hands, if we want to tame it, we need to know its basic parameters. These basic parameters will be used in 2, 3, 6, and 10 in the figure below. As for why these parameters are used, we will explain in detail when we start to pull the formula. I have to say that I hate ...Read more -
Regarding the stepping motor and servo motor, according to the different requirements of the application, choose the appropriate motor
Stepper motor is a discrete motion device, which has an essential connection with modern digital control technology. In the current domestic digital control system, stepper motors are widely used. With the emergence of all-digital AC servo systems, AC servo motors are increasingly used in digit...Read more -
what does PTO mean
pto stands for power take off . PTO is a switch control method, mainly used for speed and position control. It is the abbreviation of PTO pulse train output, interpreted as pulse train output. The main function of PTO is to obtain power from the vehicle chassis system, and then through its own co...Read more -
Analysis of motor vibration quality problems
Vibration is a very critical performance index requirement for motor products, especially for some precision equipment and places with high environmental requirements, the performance requirements for motors are more stringent or even severe. Regarding the vibration and noise of motors, we have ...Read more -
AC Motor Electric Drive System Comparison
Commonly used AC motor electrical transmission systems include rotor series resistance, dynamic braking (also known as energy-consuming braking), cascade speed regulation, rotor pulse speed regulation, eddy current brake speed regulation, stator voltage regulation and frequency conversion speed ...Read more -
How to predict motor performance from rotor turning condition?
Rotor turning is a necessary process in the production and processing of electric motors. During the turning process, it should be ensured that the rotor punches cannot be displaced or rewound in the circumferential direction, especially for rotors with windings. Because of the displacement of th...Read more -
What are the classifications of DC motors? What is the working principle of DC motors?
Introduction: DC motor is a kind of motor. Many friends are familiar with DC motor. 1. Classification of DC motors 1. Brushless DC motor: The brushless DC motor is to exchange the stator and rotor of the ordinary DC motor. Its rotor is a permanent magnet to generate air-gap flux: t...Read more -
Is the motor overheating? Just master these eight points!
The motor is an indispensable and important power provider in people’s production and life. Many motors will generate serious heat during use, but many times they don’t know how to solve it. What’s more serious is that they don’t know the reason. The resulting heating o...Read more -
Motor starting current problem
Now that EPU and EMA are more and more widely used, as a practitioner in the hydraulic field, it is necessary to have a basic understanding of motors. Let’s talk briefly about the starting current of the servo motor today. 1 Is the starting current of the motor larger or smaller than the normal w...Read more -
In the motor bearing system, how to select and match the fixed end bearing?
For the selection of the fixed end of the motor bearing support (referred to as the fixed ), the following factors should be considered: (1) The precision control requirements of the driven equipment; (2) The load nature of the motor drive; (3) Bearing or bearing combination Must be able to withs...Read more
