Abstract
A device for the de-excitation of at least one rotor winding of an externally electrically excited synchronous motor has a stator current controller. The stator current controller is designed to inject a stator current value into a stator current in such a manner that a value of an Id stator current following deactivation of the synchronous motor has a predefined positive value and is higher than the Id stator current prior to deactivation.
Claims20
A device for de-excitation of at least one rotor winding of an externally electrically excited synchronous motor, the device comprising:
- a stator current controller configured to inject a stator current value into a stator current such that a value of an Id stator current following deactivation of the synchronous motor has a predefined positive value and is higher than the Id stator current prior to deactivation.
A method for operating an externally electrically excited synchronous motor, the method comprising:
- injecting a stator current at a stator current value such that a value of an Id stator current following deactivation of the synchronous motor has a predefined positive value that is higher than the Id stator current prior to deactivation.
A non-transitory computer readable medium having stored thereon a computer program that, when executed by at least one processing device, causes the at least one processing device to execute a method comprising:
- injecting a stator current at a stator current value such that a value of an Id stator current following deactivation of a synchronous motor has a predefined positive value that is higher than the Id stator current prior to deactivation.
