CONTROL OF AN ELECTRICAL MACHINE |
摘要 |
A method of controlling an electrical machine that includes exciting a phase winding with a supply voltage, and freewheeling the phase winding when current in the phase winding exceeds a threshold. The threshold is then adjusted in response to changes in the supply voltage and/or the speed of the electrical machine. Additionally, a control system that implements the method and an electrical machine comprising the control system are described. |
