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…
