Pure electric vehicle, single motor or dual motorPure 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.

Military vehicle driver experience 800 words" Military Vehicle Driver's Experience "
As a military vehicle driver, he had many unique experiences and deep insights in driving.
Safety was the primary consideration for driving a military vehicle. The movement of military vehicles often involved military missions, the transportation of personnel and supplies, and there was no room for carelessness. On the one hand, it was necessary to study road traffic safety laws and regulations in depth. This was the basic principle of driving, the crystallization of the experience and lessons of predecessors. Learning it well was responsible for oneself, family and society. On the other hand, in actual driving, one must always be vigilant and cultivate good driving habits. For example, the operation method of the right foot was very important. The heel was placed under the brake, the accelerator was stepped diagonally, the brake hook was stepped on, and the right foot was not on the accelerator. This could prevent the wrong step on the accelerator in an emergency. When braking, you should also observe the rearview mirror in time to prevent being rear-ended. If there is no sign of slowing down, you should consider changing lanes to avoid it.
There were also many key points in terms of vehicle control. Using the accelerator to control the speed of the car instead of relying solely on the brakes, this required one to step on the accelerator in anticipation, instead of stepping on the accelerator until there was a situation and then stepping on the brakes. When crossing a curve, slow down in advance, release the accelerator when entering the curve, do not step on the brakes during the curve, and accelerate halfway out of the curve, because stepping on the brakes at the curve may cause the friction between the inner and outer wheels of the vehicle, affecting the steering function of the front wheels and causing the vehicle to lose control.
Military vehicle drivers also had to have the ability to deal with special situations. In the event of an emergency, such as a sudden obstacle in front, the first reaction should be to slow down rather than rush to change direction, especially at high speeds. Blindly changing direction could lead to serious consequences such as vehicle overturning. During driving, one's eyes could not leave the road. They could not be distracted by small movements such as adjusting the radio or holding a mobile phone. Many accidents happened in this instant.
In addition, mental fortitude was also extremely important. Whether it was facing a new driving environment, such as driving in bad weather, or the tense atmosphere when performing special missions, he had to be able to adjust his mentality in time. For example, in the railway loading and unloading platform training, in the face of the nervousness of driving on the platform for the first time, as well as the difficulties brought by the heavy rain, one had to overcome the fear and operate according to the instructions of the guide. In daily missions, even if the materials transported were different and the urgency of the mission was different, they had to complete the mission efficiently under the premise of ensuring safety.
In short, military vehicle drivers not only had to have excellent driving skills, but they also had to always remember safety and maintain a good psychological quality in order to successfully complete their missions.

Zooming lens motorThe 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.
