Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

Motors and transformers are some of the most reliable pieces of equipment installed at power plants. However, inadequate maintenance can result in trouble. While regular testing and skilled evaluation ...

Both software and hardware are parts of all motor control systems such as IGBTs, WBG semiconductors and MCUs. Industry 4.0 strongly relies on motor control for its development but energy consumption ...

Designing a closed-loop, controlled power supply or motor-control system presents two main challenges. First, the design requires sending feedback voltage or current information across an isolation ...

In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...
