Analysis of the advantages and disadvantages of using closed slots in cast aluminum rotors of motors
As people continue to pursue motor efficiency, closed slot rotors are gradually recognized by motor manufacturers. For three-phase asynchronous motors, due to the existence of stator and rotor slots, pulsation loss will occur during rotation. If the rotor uses closed slots, the effective air gap ...Read more -
Fault Cases – Causes and Effects of Motor Noise and Winding Heating
Noise is a very typical failure case of motors. It can be divided into mechanical, electrical and ventilation types based on the mechanism of its generation. In comparison, the sound caused by electricity is easy to identify, that is, it can be judged by cutting off the power supply; and the nois...Read more -
Evaluate the energy-saving effect of YE4 and YE5 motors through power consumption
For any motor consumer, the motor’s power usage is a critical factor while the motor product meets its purpose. For electric motor products, rated voltage, rated power, efficiency, speed and current are all important performance indicators, while for power consumption, power and efficiency ...Read more -

New energy tractor market has broad development space
With the continuous innovation and development of the new energy technology revolution, the manufacturing and application technology of new energy agricultural machinery has gradually matured. In recent years, many domestic agricultural machinery companies have launched new energy tractors with d...Read more -
What are the obvious differences in structure between high and low voltage motors?
The fundamental difference between high and low voltage motors lies in the difference in rated voltage of the motors. It is precisely because of the difference in rated voltage that the motor components and materials are quite different. The difference in electromagnetic wires. Due to the large d...Read more -
Will the motor winding burn out in the no-load state?
A netizen asked why the winding of the shaded-pole motor would burn out when it is running at no load? To answer this question, we analyze the reasons why the winding of the motor is burned out when it is running at no load. Compared with the load, the no-load state of the motor is an operating s...Read more -
What influence does the transmission pulley have on the performance of the motor?
Transmission is a key link in the energy conversion of motor products. Common transmission methods include gear transmission, coupling transmission and belt transmission. When coupling transmission is used, the towed equipment and the motor have the same rotation speed, that is, the angular veloc...Read more -
Are high voltage motors more prone to vibration problems than low voltage motors?
Compared with low-voltage motors, high-voltage motors, especially high-voltage asynchronous motors, are mostly based on cage-type rotor structures. During the manufacturing and operation of the motors, due to improper matching of mechanical structural parts, the motors may cause severe vibrations...Read more -
Relationship between motor temperature rise and efficiency level
Recently, the results of random inspections on motor quality at different levels have been announced one after another. From the comparison of unqualified items, it can be found that the efficiency performance of high-efficiency motors is not in compliance with the standards, which is a very seri...Read more -
Mechanism of motor bearing damage caused by variable frequency power supply
The reason why the variable frequency power supply damages the motor bearings is that there is current flowing through the bearings, and this current is in a state of intermittent connection. The intermittently connected circuit will generate an arc, and the arc will burn the bearings. There are ...Read more -
How to Analyze the Special Functions of a Rotor from Its Surface Characteristics
From the structural analysis of the rotor, we can divide the motor rotor into winding rotor and squirrel cage rotor. In comparison, due to the particularity of the production and manufacturing of the winding rotor, the degree of freedom of its structure and slot shape change is relatively small, ...Read more
