Abstract: This paper introduces a new dual redundant permanent magnet synchronous motor, establishes its mathematical model and designs its speed control and current sharing control system.
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 ...
