Embodiment 1

[0056] Such as figure 1 As shown, the present embodiment is based on the variable frequency AC motor transmission system quick selection method, the steps include:

[0057] S1. Generate the corresponding system demand characteristic curve according to the demand parameters of the transmission system under test;

[0058] S2. Select the transmission parameter value of the gearbox, and generate the corresponding demand characteristic curve of the gearbox;

[0059] S3. Select the parameters of the test motor according to the state of the current gearbox demand characteristic curve;

[0060] S4. Generate the actual output characteristic curve of the transmission system under test according to the parameters of the selected test motor;

[0061] S5. Match the generated actual output characteristic curve with the system demand characteristic curve. If the match is successful, complete the selection of the tested transmission system, otherwise adjust the transmission parameter value ...

Embodiment 2

[0097] This embodiment specifically takes the generation of the output characteristic curves of rotational speed and torque as an example, such as figure 2 As shown, in this embodiment, the specific steps for realizing the rapid type selection of the transmission system based on the variable frequency AC motor include:

[0098] Step 1: Generate the corresponding system demand characteristic curve ③ according to the demand parameters of the transmission system under test.

[0099] Step 2: Set the transmission ratio i of the gearbox.

[0100] Assume the gearbox ratio i 1 i 2 is a certain value, the value range of the transmission ratio i of the gearbox in this embodiment is specifically: 0.2≦i≦5, where i=1 corresponds to canceling the setting of the gearbox, that is, not setting the gearbox parameters.

[0101] Step 3: Generate the gearbox demand characteristic curve ② according to the currently set gearbox transmission ratio i.

[0102] In this embodiment, the demand chara...
