Designing Efficient and Reliable Brushless DC Motors

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.…

Why do I need a driver when using a high power BLDC?

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…

Motor winding classification and 7 stator winding methods!

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…

The glitches that motor cannot get used to

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…
