CONTROL OF AN ELECTRIC MACHINE |
摘要 |
A method of controlling an electric machine that includes exciting a winding of the electric machine in synchrony with zero-crossings of back emf when operating over a first speed range. The method then includes exciting the winding in advance of the zero-crossings by a fixed period of time when operating over a second speed range, and exciting the winding in advance of the zero-crossings by a period of time that varies with speed when operating over a third speed range. Additionally, a control system for an electric machine, and a product incorporating the control system and electric machine. |
