Problems solved by technology

However, in certain operating states it may be the case that the usual measurement of the phase currents at the motor phases for regulation is not desired or is not possible
As a result, precise adjustment of the motor may not be possible or difficult to achieve

Embodiment Construction

[0050] Various embodiments are now described in more detail with reference to the accompanying drawings in which some embodiments are shown. In the drawings, thickness dimensions of lines, layers and / or regions may be shown exaggerated for clarity.

[0051] In the subsequent description of the drawings showing only some exemplary embodiments, the same reference numerals may designate the same or similar components. Furthermore, general reference numbers may be used for components and objects that appear multiple times in one embodiment or one figure but are commonly described with respect to one or more features. Components or objects described with the same or general reference numerals may be implemented identically with respect to single, multiple or all features (eg their specifications), but may also be implemented differently if necessary, as long as it is not clear from the description otherwise or implicitly given.

[0052] Although the embodiments may be modified an...

Abstract

The invention relates to a device, a method and a computer program for providing adjustment variables for phase groups. The device for providing a first manipulated variable for a first phase group of a rotating field motor and a second manipulated variable for a second phase group comprises: at least one first, two input terminals for first and second input variables, respectively , the first input variable includes a first setpoint vector for the first phase group and the angular velocity of the rotor of the rotating field machine, and the second input variable includes at least one second setpoint vector and angular velocity for the second phase group; At least one first and second output terminals of the first and second adjustment parameters. The device is designed to ascertain on the basis of the first setpoint value vector and the angular velocity a first manipulated variable for the first phase group and provide it to the first phase group, and to ascertain at least on the basis of the second setpoint value vector and the angular velocity for the second The second adjusted variable of the two-phase group is supplied to the second phase group.

Description

technical field [0001] The following exemplary embodiments relate to a method for providing a first manipulated variable for a first phase group of a plurality of phase groups and a second manipulated variable for a second phase group of a plurality of phase groups of a rotating field machine (Drehfeldmaschine). Field of devices, methods and data carriers. Background technique [0002] To convert electrical energy into kinetic energy, so-called rotating field motors or three-phase AC motors as well as electric motors of other designs are used. A rotating field electric machine can comprise an annular arrangement of stators with so-called phases, which can generate a temporally variable magnetic field and thus can set a magnetic rotor, for example a mover with permanent magnets, into rotation. Rotating field motors such as permanent magnet synchronous motors (PSM or PMSM) or asynchronous motors (ASM) are used in different applications (eg hybrid vehicles, electric vehicles, ...
