Maintenance Guide for the Permennent DC Motors
1. Short-term Maintenance:
The working conditions in industries like steel rolling are challenging. Ensuring proper maintenance is crucial to avoid deterioration in the DC motor's commutation. Optimize the carbon brushes based on the actual working conditions, ensuring they are adjusted correctly. This step restores the motor's normal commutation, ensuring its efficient and uninterrupted operation.
2. Carbon Brush Selection:
Selecting the appropriate carbon brushes is vital and should be based on various technical parameters. These include material category, resistivity, density, allowable current density, speed, bending strength, and hardness.
For instance, consider a Z450-4B DC motor with a rated power of 700 kW and a rated current of 1240 A, operating at a maximum speed of 1400 r/min. If the motor operates at 90% of its rated load and you notice an oily surface on the carbon brush and a black carbon film on the commutator, it indicates wear. In such cases, opt for carbon brushes with superior resistivity, density, flexural strength, allowable current density, and speed compared to the original. Once properly adjusted, a new oxide film will form on the commutator's surface, significantly prolonging the carbon brush's lifespan to around six months.
This detailed product specification and maintenance guide provide insights into the permanent DC motor's capabilities, features, and essential maintenance practices to ensure optimal performance and longevity.
