[0083] When there are multiple matching groups of capacitance value-resistance value that meet the condition, the matching group closest to 0 can be selected as the final used capacitance value-resistance value combination according to the motor internal power factor angle, so as to obtain a more stable working condition and improve the test accuracy.

[0084] The application provides a matching method for motor test load capacitance resistance, which comprises the following steps: obtaining a target parameter; sequentially calculating resistance values and capacitance values meeting load requirements according to the target parameter to obtain a matching group, wherein the matching group comprises a matching resistance value and a corresponding matching capacitance value; determining a load capacitance current and a load motor current according to the target parameter and the matching group; judging whether the load capacitance current and the load motor current exceed corresponding threshold values; when neither the load capacitance current nor the load motor current exceeds the corresponding threshold value, determining regulation and control information according to the matching group; and sending the regulation and control information to a load component to make the load component distribute loads according to the regulation and control information, wherein the load component comprises a logic processor, a capacitance matrix composed of multiple capacitors, a resistance matrix composed of multiple resistors, and a contactor switch corresponding to each capacitor and each resistor; and the logic processor is signal connected with the capacitance matrix and the resistance matrix through the contactor switch.
