Is the center hole of the motor shaft a mandatory standard?
The center hole of the motor shaft is the benchmark of the shaft and rotor machining process. The center hole on the shaft is the positioning reference for the motor shaft and rotor turning, grinding and other processing procedures. The quality of the center hole has a great influence on the prec...Read more -
The no-load current of the motor must be less than the load current?
From the analysis of the two intuitive states of no-load and load, it can basically be considered that under the load state of the motor, due to the fact that it drags the load, it will correspond to a larger current, that is, the load current of the motor will be greater than the no-load current...Read more -
What is the reason for the running circle of the motor bearing?
certain company said that a batch of motors had bearing system failures. The bearing chamber of the end cover had obvious scratches, and the wave springs in the bearing chamber also had obvious scratches. Judging from the appearance of the fault, it is a typical problem of the outer ring of the b...Read more -
How to find the quality problems of motor windings as early as possible
Winding is a very critical element in the process of motor production and processing. Whether it is the correctness of the motor winding data or the compliance of the insulation performance of the motor winding, it is a key indicator that must be highly valued in the manufacturing process. Under ...Read more -
Why are permanent magnet motors more efficient?
Permanent magnet synchronous motor is mainly composed of stator, rotor and housing components. Like ordinary AC motors, the stator core is a laminated structure to reduce iron loss due to eddy current and hysteresis effects during motor operation; the windings are also usually three-phase symmetr...Read more -
Why do squirrel-cage asynchronous motors choose deep-slot rotors?
With the popularization of variable frequency power supply, the problem of motor starting has been easily solved, but for ordinary power supply, the starting of squirrel-cage rotor asynchronous motor is always a problem. From the analysis of the starting and running performance of the asynchronou...Read more -
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
