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 ...
The circuit in this Idea for Design provides three levels of speed control for a dc motor using a PC’s parallel port (LPT1). A C++ program performs the control functions by allowing the signals from ...
Abstract: The operation of open-winding permanent magnet synchronous motor (OW-PMSM) systems with a common DC bus configuration is inherently affected by zerosequence current (ZSC) circulation. This ...
Abstract: Five-phase machines have gained increasing attention due to their fault-tolerant characteristics. This paper proposes a fault-tolerant control method in a five-phase surface-mounted ...
