Pure electric vehicle, single motor or dual motor
Pure electric vehicles had their advantages and disadvantages.
In terms of performance, the dual-motor power performance was stronger, the vehicle accelerated faster, and the push back feeling was more obvious. There were three types of dual motor driving methods. The common method was to use two single motor with different power to control the operation of the car at high speed and low speed respectively to improve work efficiency. It could effectively improve the performance and endurance of the car, and the user experience was better. In order to cope with climbing and complicated road conditions, the motor power of the single-motor system was often large, but in actual applications, most of them were running at low speeds, which was inefficient and wasted more energy. However, the single-motor version of the Tesla Model 3 rear-bridge permanent magnet motor had a power of 202 Kilowatts, which was considered a high-power motor, which also allowed the vehicle to have better acceleration.
In terms of cost and endurance, due to the complicated operation process of the dual motor, it was necessary to coordinate the balance and control between the two motor. The technical requirements were high, the cost of building a car was greatly increased, and the endurance of the dual motor might be reduced. The cost of a single motor was relatively low. In the case of limited budget or low requirements for driving experience, mainly used for urban commutes, a single motor was a more cost-effective choice.
From the perspective of energy efficiency, the dual motor had more advantages than the single motor in terms of energy conversion efficiency. Using different power motor at low and high speeds could greatly improve energy utilization efficiency and save energy and environmental protection.
Therefore, choosing a single motor or dual motor for a pure electric vehicle required comprehensive consideration of individual performance, budget, endurance, and energy efficiency.

How to connect a single-phase motor to a four-wire motor
There were two ways to connect the four wires of a single-phase motor, the star connection and the triangle connection. Star connection is mainly used for low-power motor, starting current is small, but starting moment is also small; triangle connection is mainly used for high-power motor, starting current is large, but starting moment is also large. You can check the label on the motor shell or check the motor manual to determine the motor's connection method. Generally speaking, the star connection is marked with "Y" or "Delta/Y", and the triangle connection is marked with "Delta" or "Y/Delta".
It should be noted that among the four wires of the single-phase motor, the main wire is the power supply wire of the motor, and the auxiliary wire is used to start the motor. There were four wires because the single-phase motor needed to be started by a starting reactor or a starting reactor. These starting components needed to be connected to the motor, thus increasing the number of wires in the motor. If the four wires of the single-phase motor were connected wrongly, it might cause the motor to fail to start normally or damage the motor. If you find that the connection is wrong, you should stop using it in time and ask a professional to repair and correct the connection.

Zooming lens motor
The zoom lens motor played a key role in the operation of the zoom lens.
There were two micro-motor in the auto-aperture electric zoom lens. One was connected to the zooming ring of the lens to control the focal length of the lens when it was turned; the other was connected to the focusing ring of the lens to complete the focusing of the lens when it was turned. However, the size of this lens increased due to the increase in the number of motor and lens sets.
The electric zoom was a function that changed the focal length of the lens by driving the lens with electricity. During operation, one had to turn the zoom button on the camera by hand to drive the zoom motor in the camera, which in turn drove the movement of the zoom lens group to complete the focal length change. The electric zoom is generally operated by the electric zoom button (similar to a double switch, with W and T on both ends). Press or dial the W end, and the lens will zoom to the wide-angle end; press or dial the T end, and the lens will zoom to the telephoto end; release or stop the dial, and the zooming will stop.
In some lens products, different lenses would be equipped with different motor to meet their functional requirements. For example, the UEPZ16 - 35mm F4G lens had four XD linear motor for power zooming and two XD linear motor for lens focusing; the EPZ10 - 20mm F4G had two linear motor to provide stable focus and suppress breathing effects.
In addition, in the remote fixed-position zoom lens, such as the iron head remote fixed-position zoom lens, the use of the Force N2 zoom gear could make the photographer track the image more smooth, and its power supply method, installation precautions, etc. were also related to the motor. Different lens size needed to adapt to different zoom motor components, and also need to pay attention to avoid situations such as motor overload.

Is Ban Shu in the Legend of Ban Shu a descendant of Ban Gu?
Was Ban Shu from the TV series Ban Shu Legend a descendant of Ban Gu? The answer to this question was not completely certain because the plot of the TV series Ban Shu Legend did not clearly state that Ban Shu was a descendant of Ban Gu.
According to the storyline of the TV series Ban Shu Legend, Ban Shu was a woman at the end of the Han Dynasty. She was born into a wealthy family and later came to a small village because of the decline of her family. There, she met a young man named Ban Gu. They fell in love and got married. Ban Gu was a talented writer whose literary works had a profound influence on the literature of later generations.
Although the plot of the TV series Ban Shu's Legend did not explicitly state that Ban Shu was a descendant of Ban Gu, we could guess that Ban Shu might be Ban Gu's great-granddaughter or a descendant of his great-granddaughter. Because Ban Chao, Ban Gu's ancestor, had served as the Governor of the Western Regions at the end of the Han Dynasty, he left behind a lot of family history. If Ban Shu was a descendant of Ban Gu, then she might have inherited her ancestors 'business and left her bloodline in the Western Regions or other regions.
