Why hasn't wireless charging caught on?
Since the beginning of this year, with the explosion of various black technologies of iPhone, "wireless charging" technology has also attracted much attention from all walks of life. In fact, this black technology was pushed to the forefront of technology trends at the beginning of its launch. After a period of experience, many users have become disillusioned with this technology because it does not bring a better charging experience.

Optical fiber temperature sensor for temperature monitoring during microwave oven heating
microwave oven (microwave oven), as the name suggests, is a modern cooking stove that uses microwaves to heat food. Microwave is a kind of electromagnetic wave. Microwave oven is composed of power supply, magnetron, control circuit and cooking chamber. The power supply provides about 4000 volts of high voltage to the magnetron, which continuously generates microwaves under the excitation of the power supply, and then passes through the waveguide system and is coupled to the cooking chamber. Near the inlet of the cooking chamber, there is a rotating stirrer, because the stirrer is a metal fan, which reflects the microwave in all directions after rotation, so the microwave energy can be evenly distributed in the cooking chamber, thus heating the food. The power range of microwave ovens is generally 500 to 1000 watts.

Why do model aircraft motors use BLDC instead of PMSM?
The problem comes down to the distinction between PMSM and BLDC. The difference between the two, which I've said before in this column, is simple.

What is the working principle of brushless DC motor?
Dc brushless motor is composed of main body and driver, which is a typical mechatronics. The stator winding of the motor is mostly made of three-phase symmetrical star connection, which is very similar to the three-phase asynchronous motor. Here's how it works.
