Development Trends Of DC Motor

Power electronics, micro-electronics and AC motor speed control and the development of control technologies, many DC generator was replaced by various types of thyristor rectifier. DC motor and DC drive system in certain areas, especially the large motor, convenient operation and maintenance of AC variable speed motors and replaced AC speed system, the scope of application is reduction trends. However, and decoupling speed control of DC motor DC drive system through long-term development, has accumulated rich experience in operation and maintenance. Taking into account the AC motor and variable speed system. In the context of a given volume and run some way, there are still systems technology, economic rationality, and certain operational requirements and operating environment also depends on DC systems. Therefore, in a certain period, DC motor and DC drive systems also have potential, cannot or should not be fully replaced.
