1. A method for current regulation in a permanently excited synchronous motor, in which a commanded current i
_{R }is controlled orthogonally to a magnet-wheel flow, wherein:
from measured current of two voltage phases i_{1M }and i_{2M }a magnitude for a current-space pointer i_{AM }is determined according to
${i}_{\mathrm{AM}}=\sqrt{{i}_{1\ue89eM}^{2}+{i}_{\mathrm{YS}}^{2}}$ with the value i_{YS }being determined according to
${i}_{\mathrm{YS}}=-\text{\hspace{1em}}\ue89e\frac{2}{\sqrt{3}}\ue89e\left({i}_{2\ue89eM}+\frac{1}{2}\ue89e{i}_{1\ue89eM}\right);$ an amount of a current error is determined according to
δi _{A} =|i _{R} |−i _{AM};
the amount of the current error is added to the absolute value |i_{R}| in a correction regulation;
from the measured current of two voltage phases i_{1M }and i_{2M }and an angle command ε_{C }of the current-space pointer, a measurement is determined for angle error, according to
iδε=i _{1M}ˇsin(ε_{C})−i _{YS}ˇcos(ε_{C});
and
the angle error is added to the desired angle value via a correction regulation ε_{C}.
