It should be understood that the specific examples described herein are intended to be illustrative only and are not intended to be limiting. Moreover, all other embodiments that can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort belong to the protection scope of the present invention.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1 to fig. 3, the schematic structural diagram and the winding schematic diagram of the resolver are shown, where S1-S2 are stator excitation windings (called excitation windings for short), S3-S4 are stator quadrature axis windings, R1-R2 are rotor cosine output windings (called cosine windings for short), and R3-R4 are rotor sine output windings (called sine windings for short), the four windings have corresponding pins, and after connecting a data processing system to each pin, output signals of the stator excitation windings, the rotor sine windings and the rotor cosine windings of the resolver are measured and analyzed, so that the electrical angle and the rotational speed of the resolver can be calculated, and parameters such as the angle and the rotational speed of a measured object can be obtained. The relative angle of the stator and rotor of the resolver is referred to as the resolver angle.
When the rotary transformer runs in no-load operation, the cosine windings R1-R2, the sine windings R3-R4 and the stator quadrature axis windings S3-S4 are opened, and alternating-current excitation voltage is applied to the excitation windings S1-S2.
When the rotary transformer operates under load, the sinusoidal windings R3-R4 are loaded.
As shown in fig. 4, in order to improve the yield of the electric drive assembly after one-time assembly and reduce the repair time, the invention provides a method for detecting the wiring sequence of a rotary transformer at the front end, which combines the principle that the rotation angle of a stator and a rotor of the rotary transformer is unchanged after the fixed position is fixed through different output of the wiring methods, and the method comprises the following steps:
and S1, acquiring actual resistance values of the excitation winding, the sine winding and the cosine winding in the no-load state, inquiring a preset resistance value judgment table according to the actual resistance values of the three windings, and judging whether a wiring error exists among the three windings. Step S1 is for detecting a wiring error between windings.
And step S2, if the wiring among the three windings is correct, acquiring actual output signals of the sine winding and the cosine winding in a no-load state, processing the actual output signals according to the two windings to obtain a rotation angle of the rotor relative to the stator, inquiring a preset angle judgment table according to the rotation angle, and judging whether each winding in the three windings has a positive and negative reverse connection error. Step S2 is used to detect the reverse connection error of the positive and negative poles inside each winding.
In this embodiment, cancelled traditional dependence manual work contrast discernment wiring order is correct mode, through gathering the resistance and the angle of change soon of winding under the no-load state, compare with the standard value respectively resistance and angle of change soon and judge between the winding and whether there is the wiring mistake inside the winding through looking up, very big reduction the risk that the defective products flowed out, improved the off-line qualification rate once, reduced and reprocessed man-hour, improved electric drive assembly line productivity.
Further, the stator in the rotary transformer is a standard component with correct wiring. In the wiring sequence detection method of the rotary transformer, the wiring of the stator is correct, namely a stator which confirms that the wiring sequence is correct is fixed on a tool with a rotor, so that a magnetic field is formed, and a signal can be normally output.

If the three actual resistance values of the excitation winding, the sine winding and the cosine winding all meet the resistance requirements in the table, the judgment of the step S2 is continued if the wiring error among the windings does not exist.
In step S1, it is determined whether there is a wiring error between the three windings, and if so, the detection is terminated. If a wiring error exists among the three windings, that is, the wiring of one winding is connected to another winding in a wrong way, in step S1, the actual resistance values of the three windings of the excitation winding, the sine winding and the cosine winding are collected, and then a preset resistance value judgment table is inquired to obtain a conclusion that the wiring error exists among the three windings of the excitation winding, the sine winding and the cosine winding, and then step S2 is not performed.

Further, in step S2, the direct current is applied to the excitation winding in the no-load state, so as to collect a sine output signal of the sine winding and a cosine output signal of the cosine winding, and the rotation angle is obtained by processing according to the sine output signal and the cosine output signal. The stator can read the position signal of the rotor at any time and calculate the angle of the rotor, namely the rotation angle.
The actual output signals include a sine output signal and a cosine output signal.
In step S2, an angle difference is obtained by comparing the rotation angle with the standard angle in the preset angle judgment table, and a corresponding judgment result is obtained according to whether the angle difference exceeds a preset threshold. Various error types corresponding to the difference value obtained by comparing the rotary angle with the standard value corresponding to the correct connection method are preset in the preset angle judgment table.
Further, the method for detecting the wiring sequence of the rotary transformer further comprises the following steps:
and step S3, when the reverse connection errors of the positive electrode and the negative electrode do not exist in each of the three windings, setting a qualified identifier at a preset position of the rotary transformer.
