ので，全界磁では良好な整流が得られる。[Prior Art] An electric motor operated in a high pulsating flow has a commutating magnetic pole φ greater than that in the case of direct current operation as shown in FIGS. 5 and 6.
The rectification deteriorates due to the delay of i (1) with respect to the armature current I a (2) and the influence of the transformer electromotive force exerted on the armature coil (4) by the main pole coil (3). However, normally, the residual spark voltage e o (6) can be suppressed to a small value by shunting the main pole coil (3) with an appropriate resistance (5), so that good rectification can be obtained in the whole field.

整流性能の向上を図るのが困難である。However, since the DC motor for vehicles is controlled in a wide range from the whole field to the weak field, the impedance of the main pole circuit in the weak field is different from that of the whole field. It is difficult to improve.

F), Z WF = | Z W | a (cos W + i sin W) . If the circuit can be constructed so that Z FF = Z WF , the rectification vector diagrams of the whole field and the weak field will match. It is very difficult to match both the absolute value of impedance | Z F |, | Z W | and the deflection angles F and W , but it is possible to match either one. And, unless a large weak field is adopted, the test shows that the absolute values | Z F |, | Z W | do not have a great influence even if they do not match, and it is sufficient to match the declination. It has been confirmed. However, as shown in FIG. 7 (conventional field-weakening circuit diagram), the deflection angle W is
If the weak magnetic susceptibility is determined as in the equation (1), the value of the weak magnetic field resistance r 2 is determined, so that the declination W cannot be set to an appropriate value, so that the rectification often tends to deteriorate. It was
