Embodiment Construction

[0033] Various embodiments are now described in more detail with reference to the accompanying drawings in which some embodiments are shown. In the drawings, the thickness dimensions of lines, layers and / or regions may be shown exaggerated for clarity.

[0034] In the ensuing description of the drawings showing only some exemplary embodiments, the same reference numerals may denote the same or similar parts. Furthermore, general reference signs may be used for parts and objects that appear multiple times in one embodiment or one figure but are described in common with respect to one or more features. Parts or objects described with the same or general reference numerals may be identical in single, multiple or all features, such as their specifications, but may also be implemented differently if necessary, as long as it is not clear from the description or get other parts or objects implicitly.

[0035] Although the embodiments may be modified and changed in various ways, the...

Abstract

Embodiments relate to a processor (708) for controlling an emergency operation of a multiphase induction machine (701) upon an interruption of a first phase current (724-1; 724-2; 724-3) of a first phase of the induction machine (701). The processor (708) is designed to determine a control current setting (716-1; 716-2; 716-3), corresponding to the emergency operation, for a second phase of the induction machine (701) in a coordinate system fixed to the stator through a combination of a first target current setting (706-1; 706-2; 706-3), corresponding to a normal operation of the electric engine, for the first phase and a second target current setting (706-1; 706-2; 706-3) for the second phase in a coordinate system fixed to the stator. This distinguishes a phase angle and an amplitude of the control current setting (716-1; 716-2; 716-3) for the second phase from a phase angle and an amplitude of the second target current setting (706-1; 706-2; 706-3).

Description

technical field [0001] The invention relates to the field of controlling the emergency operation of a multiphase rotating field electrical machine in the event of a first phase current interruption of a first phase of the rotating field electrical machine. Background technique [0002] To convert electrical energy into kinetic energy, so-called rotating-field or three-phase motors are used in addition to other types of electric motors. A rotating field machine can comprise a stator with an annular arrangement of so-called phases, which can generate a temporally variable magnetic field and thus can rotate a magnetic rotor, for example a mover with permanent magnets. Rotating field electric machines, such as permanently excited synchronous machines (PSM) or asynchronous machines (ASM), are used in various applications, for example in hybrid vehicles, electric vehicles, servo drives, machine tools, etc. In these rotating field machines, a voltage intermediate circuit inverter ...
