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…
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,…
