Brushless direct current motor for use as driving motor for vehicle-cooling-fluid pump, has pulse-width modulator to generate control signals so that temporal process of voltage from bridge runs symmetrical to voltage-symmetrical line |
摘要 |
<p>The motor (10) has a switching bridge (24) controlling a pulse width modulator to generate pulse-width modulated control signals to produce flow cycles. The modulator is formed as a symmetrical operating module (16) for symmetrical mode of operation and generate the signals whose temporal pulse width process runs symmetrical to a constant pulse width symmetrical line, which lies higher than a half pulse width range, such that a temporal process of voltage supplied from the bridge in motor coils (26) runs symmetrical to a voltage-symmetrical line that lies higher than a half voltage range. An independent claim is also included for a method for operating a brushless direct current motor.</p> |
