Recently, Dad always complained that I couldn't tell whether it was red rice 2 or red rice 1 system too card, the handset noise, battery life is not enough. After more than three years of use of mobile phones, I think these problems are also forbearance for a long time, and now can not be used before they began to complain. The landlord himself is using the iPhone SE to think that the price of this mobile phone is quite high, and it would be okay if he wanted to go to Amoy to use his father for another three years. Searched for a variety of channels of new machines, the three Netcom SE approximate price of 2500. Dad refused to excuse himself for not using the Apple system. I still chose millet's thousand-dollar products. Dad is a thrifty person in his concept of mobile phones as long as less than 1,000 yuan on the line. Once I was also keen on the various parameters of mobile phones can blurted out, a variety of rom daily brush again, now no time to toss these. Select the mobile phone to follow a rice flour friend's suggestion, red rice Note 4X 799 yuan is very suitable, Jingdong orders directly. 799 price box The damping effect of the millet box has always been very good. Lifting the box by hand will slowly Mobile phone, warranty card, charger, card pin, data cable. No standard headphones 5.5 inch 1080p screen, border width quite satisfactory, perhaps the black body in the state of the screen is better visual effects The two ends of the back of the fuselage are made of metal material in the middle of the plastic material. The paint effect will make people think that it is an all-metal body. Dad had never used a mobile phone more than 5 inches before. He said that the phone couldn't hold it and it was easy to slip. It strongly urged me to buy a mobile phone. Handset, sensor, front camera with symmetrical design Below is a capacitive button, I experienced a lot of the chance of feeling misuse, when browsing an application somehow it will come back to the return key or home button Fingerprint recognition uses a back design, which means that unlocking with index finger money is the most convenient. Although the recognition rate is still good, but Dad asked me to turn off the function of fingerprint recognition. Dad used to work in the water and home improvement industry and often had hands covered with dust or gloves. Under such bad conditions, fingerprint identification, which is inherently humanized, will cause troubles. The phone also supports double-click wake-up function. The bottom is an ordinary USB excuse, and a rough speaker port, for dad's daily use of the environment will inevitably get into the dust and the like There is a headphone jack at the top and an infrared transmitter is attached to the conscience. My father and I said that with this, the air conditioner can be controlled by the mobile phone. He is dismissive of this kind of messy function, and he cannot find this function. The mobile phone comes with some built-in apps to delete, but the built-in game store and the millet wallet cannot be deleted and can only be moved to inconspicuous places. The homepage location leaves behind the most important cameras, contacts, WeChat and other functions The camera parameters I did not study, take a few pictures and iphone se do a direct comparison to see the effect (the millet on the map, the following figure iphone) This picture is a picture of the scenery taken outside the window at about 3 o'clock in the afternoon. The brightness of the millet picture is darker and the cool tone is biased. This is a close-up view with a large contrast of light inside and outside. Obviously the contrast of millet is somewhat high, and the top of the still life has been exposed. Another indoor dark light environment, you can see millet in order to enhance the brightness, noise control is not very good. Of course, these are all natural eggs, Dad's daily shooting content is not young people drying food, sun self-timer, sun travel, but to take some of the bill information or work structure of the picture, for the above-mentioned picky On the endurance ability, has always been the concern of the father. The red rice note series has always been claimed to have strong endurance. I do not know how many milliamps of battery do not know what kind of processor, but for dad, it is no problem to use the mobile phone once a day. Summarize several use cases On the 1st floor, the masters are all millet's smart hardware devices, but they are never optimistic about Xiaomi's mobile phone products. They belong to half a meter. However, when such a 799 yuan mobile phone was placed in front of me, I felt a feeling of being beaten. Very value! However, the landlord himself will not choose millet's mobile phone products. 2 miui's operating logic is getting closer and closer to ios. I have never used Xiaomi's mobile phone yet. For those who used my red rice before, my dad didn't have to do teaching work anymore. 3 Probably learned that the note4x processor belongs to the kind of weak processor, but my dad is not the king of glory or other big game is nothing more than to look at the news, chat WeChat and other needs, fully enough 4 This mobile phone case is very necessary for Dad, one is to prevent dust from falling. In general, this cell phone can give Dad another battle for two years. A Brushless DC Electric Motor (BLDC motor or BL motor), also known as electronically commutated motor (ECM or EC motor) and synchronous DC motors, are synchronous motors powered by direct current (DC) electricity via an inverter or switching power supply which produces an alternating current (AC) electric current to drive each phase of the motor via a closed loop controller. The controller provides pulses of current to the motor windings that control the speed and torque of the motor. 24v brushless motor,24v brushless dc motor,24 volt brushless motor,Brushless dc motor 24v 500w Shenzhen Maintex Intelligent Control Co., Ltd. , https://www.maintexmotor.com
Millet red rice Note4X Netcom version 3GB+16GB Champagne gold mobile China Unicom Telecom 4G mobile phone 799 yuan Red rice Note 4X Special Edition and the previous standard version uses the same Xiaolong 625 processor, the highest frequency 2.0GHz, Adreno 506 3GB memory, capacity From the original standard version of 32GB to 16GB of storage space, the other aspects of the standard version of the same, still standard 4100 mA battery, 5.5 inch 1080P screen, colorful metal shell, 13 million pixel camera, can be said in addition to Jingdong direct Link to Wikipedia 
The construction of a Brushless Motor system is typically similar to a permanent magnet synchronous motor (PMSM), but can also be a switched reluctance motor, or an induction (asynchronous) motor.
The advantages of a brushless motor over brushed motors are high power-to-weight ratio, high speed, electronic control, and low maintenance. Brushless motors find applications in such places as computer peripherals (disk drives, printers), hand-held power tools, and vehicles ranging from model aircraft to automobiles.
