Motor testing platform

The motor experimental platform is a power testing project selected according to the technical requirements of the motor. The test bench refers to the installation foundation of the motor, which uses a cast iron T-shaped groove platform with ground anchor installation to reduce the actual application of seismic isolation.

Technical requirements for motor testing platform:

1. The working surface of the motor test platform shall not have defects such as sand holes, air holes, cracks, slag inclusions, shrinkage, scratches, bumps, rust spots, etc. that seriously affect the appearance and performance.

2. The casting surface of the motor test platform should be sand and smooth, and painted firmly.

3. On flat working surfaces with precision registration levels of 0-3, sand holes with a diameter less than 15mm are allowed to be blocked with the same material, and their hardness should be lower than that of the surrounding materials. The number of sand holes blocked in the working face should not exceed 4, and the spacing between sand holes should not be less than 80mm.

4. The motor test platform should be made of fine grey cast iron or alloy materials, and its working surface hardness should be 170-220HB.

5. The working surface of the motor test platform should usually use scraping technology. The allowable surface roughness Ra for the 3-level flat working surface processed by scraping is 5um.

6. The flatness tolerance of the working surface of the motor test platform is specified in Table 2.

7. The working surface of the motor test platform should undergo color matching inspection using scraping technology. The ratio of the contact point area displayed after research is specified in Table 3, or the number of contact points in a 25mm x 25mm square area is specified in Table 3, and the number of contact points in any 25mm x 25mm area should not exceed 5 points.

4. The motor test platform should be made of fine grey cast iron or alloy materials, and its working surface hardness should be 170-220HB.

5. The working surface of the motor test platform should usually use scraping technology. The allowable surface roughness Ra for the 3-level flat working surface processed by scraping is 5um.
