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 -
Regulations on allowable starting times and interval time of electric motors
One of the most feared situations in electromechanical debugging is the burning of the motor. If the electrical circuit or mechanical failure occurs, the motor will burn out if you are not careful when testing the machine. For those who are inexperienced, let alone How anxious, so it is necessary...Read more -
How to increase the constant power speed regulation range of asynchronous motor
The speed range of the car drive motor is often relatively wide, but recently I came into contact with an engineering vehicle project and felt that the customer’s requirements were very demanding. It is not convenient to say the specific data here. Generally speaking, the rated power is sev...Read more -
If the shaft current problem is solved, the safety of the large motor bearing system will be effectively improved
The motor is one of the most common machines, and it is a device that converts electromagnetic energy into mechanical energy. During the energy conversion process, some simple and complex factors may cause the motor to generate shaft currents to varying degrees, especially for large motors, For h...Read more -
How to choose and match the motor speed?
Motor power, rated voltage and torque are essential elements for motor performance selection. Among them, for motors with the same power, the magnitude of torque is directly related to the speed of the motor. For motors with the same rated power, the higher the rated speed, the smaller the size, ...Read more -
What factors will affect the starting performance of asynchronous motors?
For variable frequency motors, starting is a very easy task, but for asynchronous motors, starting is always a very critical operating performance indicator. Among the performance parameters of asynchronous motors, the starting torque and starting current are important indicators reflecting the s...Read more -
In practical applications, how to choose the rated voltage of the motor?
Rated voltage is a very important parameter index of motor products. For motor users, how to choose the voltage level of the motor is the key to motor selection. Motors of the same power size can have different voltage levels; such as 220V, 380V, 400V, 420V, 440V, 660V and 690V in low-voltage mot...Read more -
From which performance can the user judge whether the motor is good or bad?
Any product has its suitability for performance, and similar products have its performance tendency and comparable advanced nature. For motor products, the installation size, rated voltage, rated power, rated speed, etc. of the motor are the basic universal requirements, and based on these functi...Read more
