Embodiment Construction

[0020] The invention discloses a large-scale motor test arrangement method, which is used in conjunction with a test pit, and is characterized in that it includes the following steps:

[0021] a. Preparation steps: place the motor chassis on the pad of the test pit;

[0022] b. Stator placement steps: a jack and a combination block are placed under the four supports on the stator wall, and a combination block is placed under the bottom of the stator. Press the jack and the combination block Put the above position on the motor chassis, and then hang the stator on the jack and the combined pad;

[0023] c. Rotor placement steps: Install a long shaft at the end of the rotor shaft extension, and install the upper bearing at the non-shaft extension end;

[0024] Hang a sling on the non-shaft extension end and the shaft extension end respectively, the other end of the sling is connected to the hanging plate, the hanging plate is hung on the hook of the crane, the rotor is lifted an...
