The types of motors used in drones mainly depend on their size, purpose, and performance requirements. Generally speaking, the vast majority of consumer and industrial drones use brushless motors, while some micro or toy drones may adopt brushed motors or special hollow cup motors. When choosing a motor, the following points need to be comprehensively considered: 1. Types and uses of drones: Clearly define whether your drone is for aerial photography, racing, agricultural spraying or heavy-lift transportation. 2. Total weight and load: Estimate the total take-off weight of the drone, including the frame, battery, camera and all other equipment. This determines the total thrust you need. 3. Propeller matching: Motors and propellers need to be optimally matched. Large propellers go with low KV motors, and small propellers go with high KV motors, following the principle of "big with low, small with high". It's best to refer to the "motor-propeller thrust table" provided by the motor manufacturer for selection. 4. Battery voltage: The KV value of the motor needs to be matched with the battery voltage (such as 3S, 4S, 6S, etc.) to ensure the motor operates within an appropriate power range. How to understand motor parameters: 1. KV value: The KV value represents the increase in rotational speed (RPM/V) that a motor can achieve for each additional volt of voltage in an unloaded state. A higher KV value means a faster motor speed but relatively smaller torque. Motors with high KV values are typically paired with small propellers for racing drones; while low KV value motors focus more on torque output and can drive larger propellers, making them suitable for agricultural and logistics drones that require greater load capacity and stability. 2. Stator size: Usually expressed as diameter*height (e.g., 100*33mm). Under the same KV value, a larger stator size generally indicates greater power and torque potential for the motor. 3. Rated power: The power at which a motor can operate continuously, directly affecting the load capacity and continuous flight performance of a drone. The power of motors for industrial drones is significantly higher than that for consumer drones. 4. Matching and efficiency: The motor, electronic speed controller (ESC), propeller, and battery need to be properly matched to achieve optimal performance. An unmatched configuration may lead to low efficiency, overheating, or even damage.   The motors of consumer-grade drones focus on high integration, low noise and efficiency; the motors of industrial-grade drones, on the other hand, aim for high torque, high reliability and strong load capacity, with significantly increased power; while the motors in the DIY market (such as Hobbywing and T-Motor) offer enthusiasts a wide range of performance options and customization space.

In the previous article, we know that silicon steel can be divided into oriented silicon steel and non-oriented silicon steel, which have different uses. So what are the uses of these two similar silicon steels? Today’s article will tell you. Use of Oriented Silicon Steel Oriented silicon steel, or CRGO, is an important soft magnetic material in the military and electronic industries, mainly used as high-frequency transformers, high-power magnetic amplifiers, pulse generators, general yoke coils, inductors, storage and memory components, switches and control components, magnetic shielding, and transformers operating under vibration and radiation conditions. Compared with other materials such as ferrite and amorphous materials, the iron core can be made very small due to the high saturation magnetic induction and high magnetic permeability of the 3% Si-Fe thin strip. Because it is a cold-rolled strip, it has a smooth surface, small differences between the same plates, good plate shape, and good processing performance. It can be made into iron cores of various shapes and specifications such as CD type, ring type, and rectangular type. It has a wide range of applicationsand wide frequency range (50H-20KH). Use of Non-oriented Silicon Steel Non-oriented silicon steel is mainly used in motors: Gap motors (water pumps) mainly use cold-rolled, non-oriented, uncoated silicon steel. Motors for electric welding machines are divided into DC motors and AC motors. DC motors can use uncoated cold-rolled silicon steel, and AC motors mainly use coated 600 non-oriented silicon steel. Air compressor, and pneumatic pump motors can also use uncoated cold-rolled silicon steel. The micro motors used in small household appliances mainly use non-oriented 470. Most of the motor used in CNC machine tools is 470. Motors for air conditioning compressors mainly use 600, 800, 1000, and 1300 silicon steel. Air compressor Silicon steel occupies a very important position in electrification construction. In a sense, the amount of silicon steel sheets used in a country can measure the degree of electrification in the country. Therefore, in the long run, electrical steel has great development prospects. Have any questions or requirements about silicon/electrical steel, feel free to contact us.
