Motor temperature rise is caused by the current?
Winding temperature rise is a key performance index of motor products, and plays a crucial role in motor reliability. The factors of the motor body, as well as the operating environment, load changes, etc., may cause the temperature rise level of the motor to change. When the temperature rises, w...Read more -
The magnetic shunt function of a shaft in a motor
Rotating shaft is a very key structural part of motor products, is the direct body of mechanical energy transfer, at the same time, for most motor products, rotating shaft will also be an important part of the magnetic circuit of the motor, bearing a certain magnetic shard effect. The vast majori...Read more -
Are high-voltage motors more susceptible to vibration issues in comparison with low-voltage motors?
Compared with low-voltage motors, high-voltage motors, especially high-voltage asynchronous motors, are mostly based on cage rotor structure. During motor manufacturing and operation, due to inappropriate coordination of mechanical structural parts, it may lead to serious vibration of the motor, ...Read more -
Technical essentials of eVTOL motor
1. Technical characteristics of eVTOL motor In distributed electric propulsion, motors drive multiple propellers or fans on the wings or fuselage to form a propulsion system that provides thrust to the aircraft. The power density of the motor directly affects the payload capacity of the aircraft....Read more -
Technical problems of motor powered by variable frequency power supply
The main difference between the motor powered by frequency conversion power supply and the motor powered by power frequency sine wave is that on the one hand, it operates in a wide frequency range from low frequency to high frequency, and on the other hand, the power waveform is non-sinusoidal. T...Read more -
How do professionals analyze the price of copper in the later period?
“This round of copper price rise has been promoted by the macro side, but also has the strong support of the fundamentals, but from the technical point of view it does rise too fast, that is to say, the adjustment is more reasonable.” The above industry told reporters that in the long...Read more -
How to choose high speed motor bearings?
Bearing is a key part to support the normal operation of the motor, in addition to the manufacturing process control, the design and configuration of the motor bearing is very important, such as vertical motor and horizontal motor should choose different bearing configurations, different speed re...Read more -
Which is the higher stator or rotor temperature during motor operation?
Temperature rise is a very important performance indicator of motor products, and the temperature rise level of the motor is determined by the temperature of each part of the motor and the environmental conditions. From the Angle of measurement, the temperature measurement of the stator part is r...Read more -
Why some motors use insulated end shield?
One of the reasons for shaft current is that in the manufacture of a motor, due to the uneven magnetoresistance of the stator and rotor along the axial direction of the iron core circumference, the magnetic flux is generated and the rotating shaft is intersected, thus inducing the electromotive f...Read more -
How to reduce motor iron loss?
Method of reducing iron loss in engineering design The most fundamental way is to know the reason for the large iron consumption, whether the magnetic density is high or the frequency is large or the local saturation is too serious and so on. Of course, in accordance with the normal way, on the o...Read more -
Save enough electricity to power a whole country
Improving the energy efficiency of motors and drives sounds good in principle but what does it mean in practice? On July 1st, 2023, the second step of the EU Ecodesign Regulation (EU) 2019/1781 comes into force, setting additional requirements for certain electric motors. The regulation’s first s...Read more -
Why proper cooling is important
Like in many other situations in life, the right level of cool can mean the difference between keeping things running smoothly and suffering a heat-induced breakdown. When an electric motor is in operation, the rotor and stator losses generate heat which must be managed through an appropriate coo...Read more
