Unmanned Aerial Vehicles (UAVs), commonly known as drones, are becoming increasingly important in various fields such as military, agricultural, and delivery services. The efficiency of drone motors plays a critical role in determining the overall performance of UAVs. Therefore, designing motors with high efficiency is crucial for the development and…
Brushless DC Motor Design: Improving Efficiency and Reliability Brushless DC (BLDC) motors have become increasingly popular in industrial, automotive, and consumer applications due to their improved efficiency, reduced noise, and enhanced reliability. However, designing a BLDC motor that meets the specific requirements of each application can be a challenging task.…
The underwater special propulsion motor is a highly technical electric propulsion device, whose technical content includes fluid design, motor design and material selection. It has a novel and unique structure with unique and superior characteristics, which makes it ideal for use as a propulsion system for underwater robots and also…
At this stage, many manufacturers of automation equipment have shifted their attention to brushless DC motors, preferring to use brushless DC motors instead of the previous low efficiency, large noise, and many other insurmountable defects of motors, such as three-phase asynchronous motors, stepper motors, etc. In the process of users…
Winding is one of the most important processes in the manufacturing process of electric motors, and with the development of electric motors, different “discipline categories” have been created.[1] Stator winding is distinguished by the formation of magnetic poles The stator winding can be divided into two types: The salient type…
Why do motors generate shaft currents? The current in the shaft-bearing housing-base circuit of a motor is called shaft current. Causes of shaft currents:[1] 1. Asymmetry of the magnetic field; 2. Harmonics in the supply current; 3. Poor manufacturing and installation, uneven air gap due to rotor eccentricity; 4. Gaps…
To prepare for an RC car event, you should first check with the track to see what they provide and what you need to bring. Many large races require you to bring your own table, chair, long extension cord, and power strip. It is also good to go over your…
What is a DC inverter fan? When we buy an electric fan, the manufacturer sales will refer to some high-end fans as DC inverter fans. In principle, the workflow of the so-called inverter technology is all about converting 50Hz alternating current (AC) to direct current (DC) and then to 30-130…
Introduction Vibration and noise are the most common problems in motor testing and operation. There are many causes of vibration and noise, and it is not easy to distinguish them completely. In many cases, we will attribute vibration and noise caused by vibration to the rotor dynamic balancing link, and…
With the more and more widespread use of DC brushless motors, their performance has also improved to a certain extent. However, various failures will also be encountered in the process of using the BLDC motor. Common problems with brushless motors include Overheating, Power loss, Difficulty starting or controlling the motor,…
