The requirements and influences of special environmental conditions on motor insulation
The special environmental conditions of motors can be classified into two major categories based on the nature of the environmental factors: natural climate environments and industrial environments. Natural climate environments mainly include tropical, marine, cold, underground and plateau enviro...Read more -
Bearings suitable for high-temperature, low-temperature and polluted environments!
Bearings are one of the most crucial components of motor products. Special operating conditions impose extremely high demands on the bearings themselves and their lubrication. For instance, high-temperature environments, low-temperature environments, large temperature fluctuations, and environmen...Read more -
Why is the efficiency of permanent magnet motors higher?
The permanent magnet synchronous motor is mainly composed of stator, rotor and housing components. Similar to ordinary AC motors, the stator core is of laminated structure to reduce iron loss caused by eddy current and hysteresis effect during motor operation; the windings are usually of three-ph...Read more -
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
