Summary
The subject aims one´s effort to projecting of electrical drives. It is based on definitions and terminologies, which are used in this area. There are designed and dimesioned components of DC. and AC. electrical drives. The subject is based on background knowledges from Power Electronics, Electrical Machines and Electrical Drives. Learned informations extend the knowledge base of electrical engineer, especially if his topic is aimed in area of applications and design of electrical drives.
