Current limit for an electric machine |
摘要 |
A method and apparatus for limiting current and voltage in a PM electric machine comprising: receiving a command indicative of a desired position control; obtaining a velocity value indicative of the rotational velocity of the electric machine; and computing a first voltage threshold for the electric machine based on a selected operating condition. If the voltage command exceeds the first voltage threshold, the method also includes establishing a modified voltage command as substantially equivalent to the first voltage threshold, otherwise establishing a modified voltage command as substantially equivalent to the voltage command.
