Introduction
To understand the operating principles of an electronic drive, it is necessary to understand the basic principles of electricity, electronics, and mechanical devices. In this topic, we will review the required basic concepts, and relate them to AC- and DC-drive systems. This section is by no means a complete digest of electronics and mechanics but will provide for a baseline of understanding. Consult the Appendix when more information is needed. This will be a review for some readers and a basic introduction into the electrical and mechanical world for others.
