1. Identifying the Start and End of Motor Windings Using a Multimeter When the six terminals of a three-phase asynchronous motor are lost, unclear, or rewound, it is necessary to determine which two terminals belong to the same phase, which is the start of the coil, and which is the end. Below are several methods … Read more
Recently, I was inspired by the quality lesson activities conducted by the city’s backbone teachers at the school. During the listening and evaluation session, I managed to use Phyphox and ESP32 to jointly capture the current change images produced by the rotation of a small motor’s rotor, which was quite exciting. After building the experimental … Read more
Overall View of the Device Last time, when detecting the current changes before and after the rotor of the small motor got stuck using ESP32, the induced electromotive force when the small motor was driven by an external force was measured. However, the changes in electromotive force were too drastic, and the data jumps were … Read more
Operating Modes:Operating conditions of the motor;Temperature Rise; Dielectric Properties;Protection Level;Cooling Methods:Motor structure and installation type;Noise Limits;Vibration Limits;Power RatingsOperating modes: This describes the load conditions that the motor can withstand, including starting, electric braking, no-load, power-off standstill, and the duration and sequence of these phases. The operating modes are divided into the following 9 categories: S1 … Read more
