Device for controlling electric drive motor of steering system, has determination element that determines phase of current line of electric drive motor so as to activate drive element for controlling electric drive motor

摘要

The control device has a circuit breaker (102) for interruption of a current line of an electric drive motor (103), and a drive element for driving the circuit breaker. A determination element determines the phase of the current line of electric drive motor so as to activate the drive element. The drive element and determination element are integrated in a power amplifier driver (104) for controlling the drive motor. An independent claim is included for a method for interrupting current line of electric drive motor.
