Introduction to the protection of DC motors
1. DC motors have a wide range of applications. They usually work in extremely harsh environments, such as humid, high temperature, dusty, and corrosive environments. Therefore, it is necessary to be more standardized in the construction of motors and to strengthen the management of equipment.
2. The selection principle of the protector is to enable the DC motor to fully exert its overload capacity and avoid damage, and it can also improve the reliability of the electric drive system and the continuity of production.
3. When choosing a DC motor, pay attention to practicality, that is, to meet the factors of reliability, economy, convenience, etc., and have a high performance-price ratio. First of all, the reliability of the function should be met. For example, the over-current and phase-cutting functions must be able to reliably operate over-current and phase-breaking that occur in various occasions, in various processes and in various ways. Secondly, its reliability must have adaptive stability and durability to various harsh environments. Economical, adopt advanced design and reasonable structure.
It can be seen that the protection of DC motors is to strengthen the usual management and maintenance of DC motors, plus the selection of suitable protectors, so that we can better protect our equipment.
