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 -

Explosion-proof motors can be divided into...Read more -
The next generation of permanent magnet motors will not use rare earths?
Tesla has just announced that the next generation of permanent magnet motors configured on their electric vehicles will not use rare earth materials at all! Tesla slogan: Rare earth permanent magnets are completely eliminated is this real? In fact, in 2018, ...Read more -
Optimize the motor control scheme, and the 48V electric drive system gets a new life
The essence of electric vehicle electric control is motor control. In this paper, the principle of star-delta starting commonly used in industry is used to optimize electric vehicle control, so that 48V electric drive system can become the main form of 10-72KW motor drive power. The performance o...Read more -
Why is the motor sometimes running weak?
A 350KW main motor of an aluminum wire drawing machine, the operator reported that the motor was boring and could not pull the wire. After arriving at the site, the test machine found that the motor had an obvious stalling sound. Loosen the aluminum wire from the traction wheel, and the motor can...Read more -
Japanese motor giants will give up the use of heavy rare earth products!
According to Japan’s Kyodo News Agency, the motor giant – Nidec Corporation has announced that it will launch products that do not use heavy rare earths as soon as this fall. Rare earth resources are mostly distributed in China, which will reduce the geopolitical risk of trade...Read more -
