1. The difference between inductive brushless motor and non-inductive brushless dc motor. The sense of brushless in refers to the "Hall sensor", so what is "Hall"? Hall refers to the Hall effect. Simply put, when the current is perpendicular to the external magnetic field through the conductor, there will be a potential difference between the two ends of the conductor perpendicular to the direction of the magnetic field and the current. Through the Hall effect, it is easy to know whether the motor is running at high speed or low speed. It can be seen that the non-inductive brushless motor is a brushless motor without Hall sensor feedback, which indirectly detects the rotor position commutation through the voltage and current changes in the motor winding. 2. Inductive brushless motor and non-inductive brushless motor characteristics Inductive motor can know the position of the rotor when it is at rest, and the non-inductive motor needs to rotate to determine the ...

In electrical equipment such as stepper motors, closed-loop motors, and servo motors, equipment using different insulation materials has different abilities to withstand high temperatures. Therefore, general motors have a maximum allowable temperature for their operation. Now let’s take a look at insulation materials and the temperatures they withstand. Class A insulation materials: including impregnated cotton yarn, silk, paper and other organic fiber materials, as well as enamel on ordinary enameled wires, etc., and are currently only used on transformers. The maximum allowable operating temperature is 105°C. The temperature rise of the wire group is 60℃, and the performance reference temperature is 80℃. Class B insulation materials: including mica, asbestos, glass fiber and other organic matter; materials and compositions made of organic paint or resin with improved heat resistance as a binder; enamel on polyester high-strength enameled wire; maximum allowable ...

1. Basic introduction to ammonium bicarbonate Ammonium bicarbonate, also known as baking soda powder and baking powder, is a colorless, transparent, smelly crystalline powder, which is widely used in food, medicine, cosmetics, feed and other industries. The role in feed is mainly manifested in the following aspects. 2. Promote feed digestion and absorption Ammonium bicarbonate can produce carbon dioxide gas in the gastrointestinal tract of livestock and poultry, promote the formation of an acidic environment, and make indigestible feed ingredients such as protein easier to digest and absorb, thereby improving feed utilization and reducing feed waste. 3. Improve the nutritional value of feed Due to the strong alkalinity of ammonium bicarbonate, it can neutralize some of the acids in the feed, making the nutrients in the feed easier to be absorbed by the animals, and at the same time, it can also increase the nitrogen content in the feed and improve the protein quality of the feed. ...
